Manual
Financial Concepts
A plain-language guide to every number the terminal calculates.
You don't need this to use the software. You need it to defend the software's answers in a room with a lender, a partner, or an investor — which is a different and harder job.
Each entry gives you four things: what the number means, how it's calculated here, what a good one looks like, and the mistake people make with it. That last part is usually the valuable one.
Every formula below is the formula the terminal actually runs. Where the industry uses a term loosely, this document says which definition we picked.
1The money going in
Purchase price
What you pay the seller. Not what you spend.
Closing costs
Title, legal, lender fees, transfer taxes. Typically 2–4% of purchase price. Real money that never shows up in the sale price you quote at a party.
Rehab budget
What you'll spend to make the property produce the rent you're projecting. If your rent assumption depends on a renovation, that renovation belongs here.
Total basis
Purchase price + Closing costs + Rehab
What the deal actually costs you, all in. Every return in this document is measured against basis or against equity — never against purchase price alone.
Loan amount and LTV
LTV (loan-to-value) is the share of the purchase price the lender puts up.
Loan amount = Purchase price × LTV Down payment = Purchase price − Loan amount
Note the lender lends against the price, not your basis. Closing costs and rehab come out of your pocket.
Equity / capital required
Down payment + Closing costs + Rehab
The cash that has to leave your account before this thing produces a dollar. This is the denominator of cash-on-cash, and the number an investor is actually being asked to write.
2From rent to what you keep
This chain is the spine of every income property. The terminal draws it as a waterfall for a reason: each step is a place money leaves.
Gross scheduled rent
Every unit, fully rented, twelve months. A number that will never happen.
Vacancy allowance
The share of gross rent you won't collect — turnover, downtime, non-payment. 5% is the common default; a tight submarket might justify 3%, a rough one 8%+.
Vacancy loss = Gross scheduled rent × Vacancy rate
Effective gross income (EGI)
Gross scheduled rent − Vacancy loss + Other income
What you actually collect. "Other income" is laundry, parking, storage, pet fees — small, real, and frequently forgotten.
Operating expenses (opex)
Taxes, insurance, management, maintenance, utilities you pay, HOA, reserves.
What is NOT opex: the mortgage. Debt service is not an operating expense. Keeping them separate is what makes NOI comparable between a property you financed and one you bought cash.
Net operating income (NOI)
EGI − Operating expenses
The single most important number in income real estate. It's the property's earnings, independent of how you paid for it. Two buyers with different loans looking at the same building compute the same NOI.
Annual debt service
Monthly mortgage payment × 12
Principal and interest. Not taxes and insurance — those are already in opex, and counting them twice is a common and expensive error.
Cash flow
NOI − Annual debt service
What lands in your account. Positive is the floor, not the goal.
3The four numbers that decide a rental
Cap rate
Cap rate = NOI ÷ Purchase price
The unlevered yield. What the property earns as a percentage of its price, before any loan. It's how you compare a duplex to an apartment building to a strip mall on one axis.
Good: varies entirely by market. In South Florida, 5–6% is market, 7%+ is strong.
- On cost (
NOI ÷ purchase price) — what the terminal shows when you're
underwriting a purchase. Your yield.
- On value (
NOI ÷ current estimated value) — what the terminal shows for
a property you already own. The market's yield.
A property bought at a 7% cap that has appreciated 40% is now a 5% cap asset. Both are true. They answer different questions: the first asks "was this a good buy," the second asks "should this capital stay here."
Cash-on-cash return
Annual cash flow ÷ Total cash invested
The levered yield. What your actual money earns in year one.
Good: 8%+ is the target the terminal uses.
DSCR (debt service coverage ratio)
NOI ÷ Annual debt service
How many times over the property's earnings cover the loan payment. This is the lender's number. At 1.25x, NOI can fall 20% before you're paying the mortgage out of pocket.
Good: 1.25x is the standard floor. Below 1.20x most lenders decline. Below 1.0x the property does not pay for itself.
Monthly cash flow
Cash flow ÷ 12. The number you feel. Negative cash flow means the property is a bet on appreciation, which is a different and riskier investment than the one you think you're making.
How the terminal grades it
| Verdict | Condition |
|---|---|
| Pass | DSCR ≥ 1.25 and cash-on-cash ≥ 8% and positive cash flow |
| Marginal | Covers debt, but returns are tight |
| Fail | Negative cash flow or DSCR < 1.0 |
"Marginal" is not a rejection. It's the deal that becomes a Pass if you get the price down, the rate down, or the rent up — and the terminal tells you which.
4Multifamily additions
Everything above still applies. These are the numbers that only appear once there's more than one unit.
Unit mix
The rent roll by unit type — how many 1BRs at what rent, how many 2BRs at what rent. Gross scheduled rent is built from this rather than typed in, so a rent assumption is always attached to a specific unit.
Gross potential income (GPI)
Gross scheduled rent + Other income
Before vacancy. The top of the funnel.
Expense ratio
Operating expenses ÷ EGI
Opex as a share of collections. Good: 35–45% for most multifamily. Under 30% usually means something is missing from the expense list — reserves and management are the usual omissions.
Price per unit
Purchase price ÷ Total units
The fastest comparison between two buildings in the same submarket. Useless across submarkets.
GRM (gross rent multiplier)
Purchase price ÷ Annual gross scheduled rent
A rough screen. Lower is cheaper. It ignores expenses entirely, so it's for sorting a list of twenty properties, never for deciding on one.
5Time: what a hold is actually worth
The numbers above are all year-one snapshots. They can't tell you whether a 5% cap deal with strong rent growth beats a 7% cap deal in a flat market. For that you need a projection.
Hold period
How many years before you sell. The terminal defaults to 5.
Rent growth and expense growth
Annual increases applied to the projection. Defaults: 3% rent, 2.5% expenses. The gap matters more than either number — if expenses grow faster than rent, NOI shrinks every year and the exit gets worse.
Capex reserve
Money set aside annually for roofs, HVAC, and the things that don't break until they do. Default 3% of EGI. It reduces cash flow on paper and prevents a crisis in practice.
Exit cap rate
The cap rate you assume a buyer will pay when you sell.
Sale price = Forward NOI ÷ Exit cap rate
Default 6%.
This is the most powerful assumption in the entire model and the one you control least. A 5% exit cap versus a 7% exit cap changes the sale price by 40% on identical NOI. This is why the terminal shows a sensitivity matrix across exit caps rather than a single answer.
Costs of sale
Commissions and closing on the way out. Default 7%.
IRR (internal rate of return)
The annualized return that accounts for how much you get and when. A dollar in year one is worth more than a dollar in year five, and IRR is the only metric here that knows that.
- Levered IRR — the return on your equity, after debt. This is your number.
- Unlevered IRR — the return on the whole property basis, ignoring
financing. This is the property's number, and it's how you tell whether a good return came from a good building or just from cheap debt.
Good: 12–15%+ levered on a stabilized hold; developers want more.
Equity multiple
Total dollars back ÷ Total dollars in
2.0x means you doubled your money, whenever that happened. IRR tells you how fast; the multiple tells you how much. Neither is sufficient alone.
Payback year
The year cumulative cash flow alone has returned your equity — before any sale. A deal that pays you back in year four is a fundamentally different risk than one that only works if the exit does.
NPV (net present value)
Today's value of all future cash flows, discounted at your required rate (default 8%). Positive means the deal beats your hurdle. Mostly useful for comparing two deals of different sizes and shapes.
6Development
A development is not a purchase. You're not buying income, you're manufacturing it, and the numbers change accordingly.
The cost stack
Land + acquisition closing — the site, plus the cost of getting it.
Hard costs — the physical build.
Hard costs = (Buildable ft² × Cost per ft²) + Demolition
Demolition — teardown and abatement. A hard cost in its own right.
Soft costs — design, engineering, permits, fees, legal, insurance. Expressed as a percentage of the vertical build only, plus entitlement.
Entitlement — rezoning, impact studies, the cost of earning the right to build. A fixed pursuit cost, not a percentage of anything, so it sits on its own line.
Contingency — the budget for what you haven't thought of.
Contingency = (Vertical build + Demolition) × Contingency %
Good: 5% on a simple ground-up, 10%+ on a renovation or anything touching an existing structure. A developer who carries no contingency is carrying it in their equity instead.
Loan-to-cost (LTC)
Construction lenders size against cost, not value.
Loan = Cost before financing × LTC
Typically 60–70%. The rest is your equity, and unlike a purchase loan, it generally goes in first.
Interest reserve
Construction interest, capitalized into the loan.
Loan × Rate × (Months ÷ 12) × Average outstanding %
You don't draw the whole loan on day one — you draw as you build. The average outstanding percentage (typically ~60%) reflects that. This is real money and it grows every month the schedule slips.
Total development cost (TDC)
Land + Hard + Soft + Contingency + Interest reserve
All in.
Cost per ft²
TDC ÷ Buildable ft²
The number you compare to other projects and to what the market will pay per foot. If your all-in cost per foot approaches market sale price per foot, stop.
GDV (gross development value)
What the finished product sells for. The terminal derives it from market $/ft² × buildable area when you give it a per-foot number, because that's how a developer actually thinks — and because GDV should move when the building gets bigger.
Profit and margin — the sell exit
Net sale = GDV − Selling costs Profit = Net sale − TDC Margin on cost = Profit ÷ TDC
| Verdict | Margin on cost |
|---|---|
| Pass | ≥ 15% |
| Marginal | 8–15% |
| Fail | Below 8%, or a loss |
Good: developers typically target 15–20%+. Below 15% there isn't enough room between you and a bad surprise.
Return on equity and equity multiple
Return on equity = Profit ÷ Equity required Equity multiple = (Equity + Profit) ÷ Equity
Margin on cost measures the project. Return on equity measures you — the same project with more leverage produces the same margin and a much larger return on equity, along with much larger risk.
The hold exit: yield on cost and development spread
If you're building to keep rather than to sell, profit isn't the test. The test is whether building beats buying.
Yield on cost = Stabilized NOI ÷ TDC Development spread = Yield on cost − Market cap rate
Development spread is the whole argument for developing. If the market pays a 5.5% cap for finished product and you can build to a 7% yield on cost, you created 1.5 points of value that nobody sold you. If the spread is zero, you took two years of construction risk to buy at market — you should have just bought.
| Verdict | Spread |
|---|---|
| Pass | ≥ 1.5 points |
| Marginal | 0.75–1.5 points |
| Fail | Below 0.75 points |
Note that spread is measured in percentage points, not percent. 7.0% against 5.5% is a spread of 1.5 points.
7Once you own it
Different questions apply to an asset you hold than to one you're buying.
Equity
Current estimated value − Loan balance
What's yours today. Grows from both paydown and appreciation.
Current LTV
Loan balance ÷ Current value
Leverage today, not at origination. This is what determines whether you can refinance and pull capital out.
Debt yield
NOI ÷ Loan balance
The lender's risk lens, and the one metric that can't be manipulated by interest rates or amortization. Good: 10%+.
Return on equity
Annual cash flow ÷ Current equity
The question nobody asks often enough: should this capital stay here? A property throwing $12k on $400k of trapped equity is earning 3%. It may have been a great buy. It's now a poor place to leave money.
Break-even occupancy
(Operating expenses + Debt service) ÷ Gross potential rent
How full the building must stay to cover everything. Good: below 85%. At 95% you have almost no margin for a bad quarter.
Appreciation
Total and annualized change against your purchase price. Real, but the least reliable of your returns — it's the one the market decides.
8Splitting the profit
When other people's money is in the deal, the returns have to be divided. The structure below is what a family office or institutional LP expects to see.
LP and GP
The LP (limited partner) is the investor: money in, passive, limited liability. The GP (general partner, or sponsor) finds the deal, executes it, and usually co-invests alongside the LP.
Pari passu
Latin for "on equal footing." Capital that ranks equally gets paid equally, pro-rata. In this model, the GP's co-invested dollars are treated exactly like the LP's for return of capital and preferred return — the sponsor's own money gets no special treatment.
Return of capital
Before anyone earns anything, everyone gets their money back. First claim on every distribution.
Preferred return ("the pref")
A minimum annual return to capital before the sponsor earns a promote. Typically 8%. It is not a guarantee — it's a queue position. In a bad deal, the pref simply goes unpaid.
Important: the pref accrues. A year that pays nothing doesn't erase the obligation; it carries forward and must be caught up before the sponsor sees promote dollars.
Promote (carried interest)
The sponsor's share of profit above the pref — payment for finding, structuring and executing the deal, as distinct from funding it. Typically 20%.
"80/20 over an 8% pref" means: capital gets its money back plus 8% a year, then everything beyond that splits 80% to the investor pool and 20% to the sponsor.
Hurdle and tiers
A hurdle is an IRR level at which the split changes. A tier is the band between two hurdles. A common structure:
| Tier | Investors | Sponsor promote |
|---|---|---|
| Up to 8% IRR (the pref) | 100% | 0% |
| 8% – 15% IRR | 80% | 20% |
| Above 15% IRR | 70% | 30% |
The sponsor's take rises as the outcome improves. That's the point: it aligns the person running the deal with the people funding it.
The waterfall
The whole sequence, in order: return of capital → preferred return → tiered splits. Money fills each level before touching the next, like water.
How to read one: the number that matters to an investor is not the split percentage, it's what actually reaches them in dollars, and at what IRR. A generous-sounding 70/30 on a deal that clears its hurdles beats an 80/20 on one that doesn't.
9Risk
Every number in this document is one scenario. It is, specifically, the scenario least likely to happen — the base case is a single point on a distribution.
Sensitivity
Re-running the deal while moving the assumptions you're least sure about, and seeing where it stops working.
For a development: cost overrun against sale value. For a hold: exit cap rate against rent growth. Those pairs aren't arbitrary — they're the two variables in each deal type that you don't control and can't promise.
Break-even
The point at which profit reaches zero.
"Costs can run 27% over budget before the profit reaches zero."
This is the single most useful sentence you can put in front of an investor, because it converts an abstract projection into a margin of safety. It is also the sentence that keeps you honest: if the answer is 4%, you don't have a deal, you have a hope.
Margin of safety
The distance between your base case and the point of failure. Everything in this section exists to measure it. A deal with a 12% margin on cost and 30% of overrun tolerance is safer than one with 20% margin and 8% tolerance — and only sensitivity analysis will tell you that.
Quick reference
| Metric | Formula | Target |
|---|---|---|
| NOI | EGI − Opex | — |
| Cap rate | NOI ÷ Price | 5–7%+ |
| Cash-on-cash | Cash flow ÷ Cash invested | 8%+ |
| DSCR | NOI ÷ Debt service | 1.25x+ |
| Expense ratio | Opex ÷ EGI | 35–45% |
| Break-even occupancy | (Opex + Debt service) ÷ GPR | < 85% |
| Debt yield | NOI ÷ Loan balance | 10%+ |
| Levered IRR | Time-weighted return on equity | 12–15%+ |
| Equity multiple | Dollars out ÷ Dollars in | 1.8x+ over 5 yrs |
| Margin on cost | Profit ÷ TDC | 15–20%+ |
| Development spread | Yield on cost − Market cap | 1.5+ points |
| Preferred return | — | 8% |
| Promote | — | 20% |
Targets are conventions, not laws. A 5% cap in a supply-constrained submarket with 6% rent growth can beat an 8% cap where nothing is growing. The metrics tell you what a deal is; judgment tells you whether that's the deal you want.

Features
What every part of the terminal does, and why it's there.
This is a tour, not a reference. Each entry is short on purpose — you'll understand any of these faster by opening it than by reading about it. For the meaning of the numbers themselves, see Financial Concepts.
The tour follows a deal's life: find it, underwrite it, build it, own it, report on it, raise against it.
Public — no account needed
Underwriting tool · /tool
Three modes on one screen: single rental, multifamily, and ground-up construction. Enter a deal, get a verdict — Pass, Marginal, or Fail — with the metrics behind it.
Market heat map · /markets
South Florida appreciation by ZIP code, painted across the tri-county area. Built on FHFA house-price-index growth rates.
Pulse · /pulse
A published newsletter — macro context, market notes, and selected deals.
The desk
Dashboard · /account
Portfolio value, equity, income and allocation, drawn rather than tabulated. Alerts surface what needs attention.
Saved analyses · /account/underwriting
Every deal you've underwritten, kept. Reopen, compare, share.
Underwriting
The three modes
Rental for a single income property. Multifamily adds a unit-mix editor so rent is built from real units rather than typed as a total. Construction models a build instead of a purchase.
Verdict badge
Pass / Marginal / Fail against DSCR, cash-on-cash and cash flow — with guidance on what would move a Marginal into a Pass.
Multi-year pro forma
Projects the hold: rent and expense growth, capex reserve, exit cap, costs of sale — producing levered and unlevered IRR, equity multiple, payback year.
Sensitivity matrix
The deal re-run across a grid of assumptions, colored by whether each outcome still works. Cost overrun × sale value for a development; exit cap × rent growth for a hold.
Credit hub
Lender term sheets side by side — LTV or LTC, rate, points, amortization — each showing what it does to DSCR, cash to close, and returns. Pick one and it fills the financing inputs above.
Development
Project types
Ground-up, teardown & rebuild, gut rehab, conversion, entitlement. The choice reshapes the inputs, the analysis, and the milestone list — a teardown gets a demolition line; an entitlement play gets pursuit costs.
Suggested defaults
Every type arrives with sensible starting numbers. All of them are editable, and changing type never overwrites a value you typed.
Budget tracker
Budget by category against real costs as they land. Over-budget lines flag themselves; contingency burn is tracked separately.
Draws and change orders
Equity and loan draws, dated. Change orders approved and pending, netted against the budget.
Schedule
Milestones with target and actual dates, weighted for percent complete. Projects a completion date from the slippage so far.
Live re-forecast
The project re-underwritten against what's actually happened — spent to date, cost to complete, projected profit, and the delta versus the original underwriting. Reads on track, eroding, or at risk.
Alerts
Margin erosion, contingency burn, schedule slip — surfaced on the project and on the dashboard.
Location
Geocode the address and the project carries a map, used on the presentation's location page.
Media gallery
Photos, renders, site plans and documents. Images are downscaled in the browser before upload, so a 6MB phone photo is stored and served as a few hundred kilobytes.
Project log
Dated notes by category — site visit, decision, risk, update. Each note has a checkbox controlling whether it appears in the presentation.
Portfolio
Properties
Acquisition, financing, income and expense, valuations — with metrics computed from the real financing rows rather than from underwriting assumptions.
Actuals
Record what really happened, period by period, next to what was projected.
Capital ledger
Every real dollar in and out, dated — producing fund-style metrics: DPI, TVPI, and XIRR since inception with today's equity as the terminal value.
Ownership
A simple cap table per property: who holds what percentage.
Equity waterfall
Return of capital, preferred return, then tiered promote splits. Tiers, hurdles and shares are all adjustable.
Exit scenarios
Hold, refinance, or sell — compared on the same numbers, with rule-based suggestions.

Appraisals, contracts, statements, stored per property.
Investors
Investor records
Contacts, their stakes, and their participation across deals.

Deal sheet · /deal/[token]
A public, branded, read-only page for an analysis or a property: the tests as gauges, sources and uses, the income or profit waterfall, the hold projection, the sensitivity matrix, and every number behind the charts.
Investor split on a share
Optionally show the LP/GP split on a shared sheet: preferred return, promote, and what each side receives.
Link expiry
Shared links expire — 90 days by default, adjustable to 30, 180, or never. An expired link shows a branded page offering a fresh one, not an error.
Analytics per share
View counts, plus where and when.
Prospecting
Prospects database · /account/prospects
Internal only. Developers to approach, annotated with their zone's appreciation so the strongest submarkets rise to the top.

Access control
Sign-in is invitation-based: an allowlist, with requests queued for approval.
Audit trail
An immutable record of who changed what and when.
Error monitoring
Every server error is captured, grouped by cause, and shown in the admin panel. A new one emails you.
Rate limiting
The endpoints a stranger can reach are capped.
What holds it together
Three properties are worth stating plainly, because they're the reason this isn't a spreadsheet with a website on it:
One set of numbers. Your view and the investor's view are rendered from the same computation. They cannot disagree.
Private by default. Row-level security means every record is scoped to its owner in the database itself, not just in the interface. Sharing is an explicit act, per deal, and revocable.
Nothing is stale. Presentations read live data. The one deliberate exception is an issued investor statement, which is frozen on purpose.
Figures produced by this software are estimates based on the assumptions you enter. They are not financial, investment, legal, or tax advice.
