Every other calculator gives you a number. This one gives you the reason.
Type in a deal and most tools hand back a ratio. The question you actually need answered is how much you can borrow and what’s holding it back. This calculator solves for both.
Check a deal
Enter your down payment and see the DSCR, cash flow, cash-on-cash, and full PITIA for that exact structure.
Find my max loan
Skip the down payment. The tool solves for the largest loan that clears a 1.00 DSCR and stays under your leverage ceiling.
See the binding constraint
It names what's limiting you — the LTV ceiling or the ratio — and when it's the ratio, it shows that taxes and insurance are the cause.
The formula and the rules, stated plainly
We publish the actual assumptions behind the tool so you can trust the output — and so you can run your deal before you talk to anyone.
How Andes Mortgage calculates DSCR
On interest-only loans the denominator is ITIA. A DSCR of 1.00 means rent exactly covers the payment; 1.25 means the property earns 25% more than the payment requires.
The rent we count: the lower of your signed lease or the appraiser’s market-rent estimate (Form 1007). A higher lease can be used with three months’ proof of receipt
Max loan by LTV — up to 85% for a 700+ file, stepping to 80% (680–699), 75% (660–679), 70% (620–659). Best available; actual varies by lender, loan size, and reserves.
Max loan by ratio — the largest loan whose PITIA keeps DSCR at 1.00 given your rent, taxes, and insurance.
The smaller of the two governs — and that's your binding constraint. The tool reports which one and why.
The rent we count: the lower of your signed lease or the appraiser’s market-rent estimate (Form 1007); short-term rental income is counted at 75–100% depending on the lender.
Why your taxes and insurance can break a DSCR deal
Because they sit in the denominator. Two identical properties with the same rent and price can land on opposite sides of the 1.00 line purely on insurance — which is exactly why a Florida coastal deal can fail where an Atlanta deal sails through.
1.13
Atlanta, GA – Capped by LTV
$300K, $2,400 rent, ~$390/mo taxes + insurance. The ratio clears with room, so you’re limited only by the 85% leverage ceiling. The deal works.
0.97
Tampa, FL – Capped by the ratio
$350K, $2,600 rent — but ~$500/mo wind + flood insurance and higher taxes push PITIA past what the rent supports at 1.00. Same product, different limit
The calculator surfaces this automatically: when the ratio binds, it shows exactly what share of your payment budget taxes and insurance are eating.
Do you need a 1.25 DSCR? Not with us.
Most calculators — and many lenders — build around a 1.25 minimum. Our programs qualify at 1.00, with options down to 0.75 and true no-ratio below that. That difference can be the whole deal.
1.00
DSCR of 1.00 is preferred. But we don’t turn deals away with <1.00 debt coverage ratios
Rent covers the payment — you qualify. Sub-1.0 and no-ratio programs exist for tighter deals, at a higher rate.
1.25
The typical competitor bar
Many tools and direct lenders won’t clear a deal below 1.25 — which quietly rules out properties that would qualify with us.
The calculator surfaces this automatically: when the ratio binds, it shows exactly what share of your payment budget taxes and insurance are eating.

DSCR calculator questions
Get answers to some of the most common questions about DSCR loans for real estate investors
How is DSCR calculated?
DSCR = gross monthly rent ÷ PITIA (principal, interest, taxes, insurance, and HOA). A 1.00 ratio means the rent exactly covers the payment.
What does "which constraint binds" mean?
Every DSCR loan is capped by two things at once: your maximum LTV and the DSCR ratio. Whichever produces the smaller loan is the one limiting your deal — and it tells you what to change to borrow more.
What DSCR do I need to qualify?
Does the calculator require my personal information?
No. Full results are shown free with no login. You can optionally email yourself the analysis, but nothing is gated.
