Live STR engine

Underwritten DSCR 0.97x

DSCR of 0.97x is below 1.0x — the qualifying rent does not cover the full monthly payment. Consider increasing STR revenue projections, reducing the loan amount, or checking if a no-ratio DSCR program (which skips the rent-to-payment test) applies.

STR assumptions

Estimates are fine — numbers update live. LTR lease rent is used as a fallback if STR income does not qualify.

State

Purchase PriceWhat you're paying for the property.

LTVLoan ÷ value. 75% LTV = 25% down. Lower LTV = better rates and more programs.

Note RateYour loan interest rate. Use today's market rate as an estimate.

LTR Lease Rent /moWhat the property would rent for on a standard 12-month lease. Used as World 1 fallback if STR income doesn't qualify.

STR Projected /moYour estimated average monthly STR revenue over a full year (include slow months). Used for World 2 qualifying.

STR Documented /moAverage monthly revenue from actual booking history (tax returns, platform statements). Used for World 3 qualifying — the strongest evidence.

Annual TaxesProperty taxes per year. Find on county assessor site.

Annual InsuranceHomeowners/STR insurance per year. STR policies typically cost more than standard HO.

Monthly HOAHOA dues per month. Enter 0 if none. Some HOAs restrict STR — check your HOA docs.

Investor is U.S. resident

Uncheck if foreign national (non-resident alien). FIRPTA withholding applies to non-US investors.

Local STR rules

Answer what you know. Anything left unanswered keeps the legality verdict at UNCERTAIN — the tool will not assume a permissive jurisdiction on your behalf.

City / jurisdiction

HOA policy on short-term rentalsLocal enforcement intensityMinimum stay (nights)Shortest booking the jurisdiction allows. 0 if there is no minimum. 7 or more effectively rules out normal STR operation.

STR permit is held for this property

A current, valid permit in the property's own name.

New permits are still available

Uncheck if the jurisdiction caps permits and the cap is full. A closed cap with no permit in hand means no permit can be obtained, which prohibits STR outright.

Owner occupancy is required

Some jurisdictions only permit STR in an owner-occupied property.

STR legislation is pending

A proposed ordinance or bill that could change these rules.

underwritten DSCR

Lenders evaluate STRs using three qualifying scenarios. The tool picks the best one that applies (marked "Selected"). World 1 uses the long-term lease rate. World 2 uses your projected STR average. World 3 uses documented historical income.

Month-by-month — does it cash flow all year?

Each bar shows the occupancy index for that month (based on US national AirDNA seasonality data) and the resulting monthly DSCR. Green = covers the payment; yellow = just covers; red = cash shortfall that month. Check the off-season warning below if any months fall short.

Legality gate — TX

UNCERTAIN

STR status is UNCERTAIN. HOA STR policy is unknown — verify before proceeding. Moderate enforcement without a permit — obtain permit before relying on STR income. STR income is shown only as a speculative scenario and should not be relied upon for lender qualification without resolution.

LTR ONLY

How qualifying rent is chosen: State TX legality status: UNCERTAIN — STR income is not permitted for qualifying in this state; the engine falls back to World 1 long-term-lease rent. Selected scenario: World 1 — Long-term Market Rent, qualifying rent used: $3,000/mo. Preliminary estimate — not a commitment to lend. Submit a scenario review for exact underwriting.

Preliminary estimate — not a commitment to lend. STR revenue projections use national AirDNA seasonality indices and are not a guarantee of income. Final DSCR qualification is subject to full underwriting. Submit a scenario review for exact underwriting.
