The property
Value and the income the lender will underwrite.
Lenders size against the lower of the two on a purchase
Usually the lesser of your lease and appraised market rent
Parking, storage, pet rent
Reassessed at your purchase, not the seller's bill
Sizes the loan only on the NOI basis, but always drives the cash flow
Of collected rent. Sizes the loan on the NOI basis; always in the cash flow.

1.20 is common. Some programs go to 1.00 or below.
Interest-only sizes a larger loan and leaves the balance intact
Most residential DSCR programs use the first. Ask before you size.

Coverage is the binding limit
The income caps you $11,591 below the LTV ceiling, so a larger down payment buys you nothing — it only shrinks a loan you were already not getting. What moves this number is rent, a longer amortization, an interest-only period or a lower rate. Rent of $2,748 a month, which is $98 more than today, would push you up to the LTV cap.

The crossover rent
The rent at which the two ceilings meet. Below it the coverage test decides your loan; above it the LTV cap does, and extra rent stops helping.
$2,748
You are $98 a month short of it. Every dollar of rent up to that point buys more loan; past it, none does.

Minimum ratios are the dial programs turn most. Where the coverage cap crosses your LTV cap is where shopping for a looser ratio stops paying.

How this is calculated
A DSCR lender applies two independent ceilings and lends the lower of them. The calculator computes both and then tells you which one produced your answer, because that is the fact that determines what to do next.
The first is loan to value: value × maximum LTV. It has nothing to do with the income and moves only if the appraisal or the program changes. The second is coverage. On the gross-rent convention most residential DSCR programs use, the qualifying payment is annual PITIA = gross rent ÷ minimum DSCR, and since taxes, insurance and HOA sit inside PITIA but do not shrink when the loan does, the payment the loan itself may carry is gross rent ÷ minimum DSCR − escrow. On the net-operating-income convention it is simply NOI ÷ minimum DSCR.
Turning that allowed payment back into a balance is the annuity inverted: loan = payment × (1 − (1 + r)^−n) ÷ r, with r the monthly rate and n the number of payments. On an interest-only loan there is no amortization to invert and it collapses to loan = annual payment ÷ annual rate, which is why interest-only supports a materially larger balance on the same rent.
The crossover rent is the figure that makes the two ceilings equal. Below it the coverage test binds and extra down payment buys you nothing; above it the LTV cap binds and extra rent buys you nothing. It is solved by taking the payment on the LTV-capped loan and asking what income the minimum ratio would need to support it, then working back through vacancy and operating expenses to a monthly rent.
The effective cost is a true annual percentage rate, not the note rate plus a fudge. Points and lender fees are deducted from the proceeds at period zero, the scheduled payments follow, and the rate that discounts that series to zero is solved for by bisection. Third-party closing costs — title, appraisal, recording — are shown in the cash to close but deliberately kept out of the cost of the money, because you would pay them to any lender.
One thing that figure is not: a worst case. The points and fees are spread across the full amortization, which is the longest life the loan could have and therefore the cheapest the charge can look. Sell or refinance in three years and the same dollars land in a third of the time — read the number as the floor on what the money costs, not the ceiling.
Common questions
What is a DSCR loan?
An investment-property mortgage underwritten on the property's income rather than the borrower's. There is no W-2, no tax return and no personal debt-to-income test; the lender asks whether the rent covers the payment and whether the loan is small enough against the value. That is why this calculator has no income fields for you at all. In exchange you generally pay a rate one to three points above an owner-occupied loan, put twenty to twenty-five percent down, and sign a personal guarantee even when the borrower is an LLC.
Why is my maximum loan lower than the LTV cap?
Because two limits apply and you get the smaller of them. The LTV cap is a fixed percentage of value; the coverage cap is whatever loan the rent can service at the lender's minimum ratio. When the coverage cap is the smaller one, the property is not producing enough income to carry a loan that size, and no amount of down payment changes that — more down payment only reduces the loan you were already allowed. The fix is more rent, a lower rate, a longer amortization, or an interest-only period.
Does interest-only really get me a bigger loan?
Yes, and it is the most common lever on a DSCR file. An interest-only payment on the same balance is roughly fifteen to twenty-five percent smaller than a thirty-year amortising one at today's rates, so the same rent services a proportionally larger loan. The cost is that the balance does not fall: at the end of the interest-only period you either refinance, sell, or start amortising over a shorter remaining term at a much higher payment. Lenders also price interest-only with an add-on, which claws back part of the benefit.
Do points and lender fees change the loan amount?
No. Both caps are computed on the loan amount, and the fees come out of what you receive or out of your pocket at closing — they do not reduce what you are approved for. They do change what the money costs. Two points on a loan you hold three years is worth roughly two-thirds of a point on the rate; on a loan you hold ten years it is closer to a quarter point. The effective cost figure on this page spreads the lender's charges across the full term, which is the most favourable reading of them — a shorter hold concentrates the same charge into fewer years and pushes the real cost well above the figure shown.
What rent does the lender use?
Usually the lesser of the signed lease and the appraiser's market rent, taken from the 1007 rent schedule ordered with the appraisal. A vacant unit is underwritten at appraised market rent, sometimes with a haircut. This matters for sizing: a lease you wrote below market, or a long-tenured tenant you never raised, caps the loan you can get even though the property would rent for more tomorrow. Run the calculator at both rents and treat the difference as the cost of that lease.
Are these thresholds fixed?
No. Minimum coverage ratios, LTV caps and the way each lender computes the ratio all vary by program, by credit score, by whether the property is a short-term rental and by how many financed properties you already hold. The 1.20 minimum and the 75 to 80 percent LTV cap in the defaults here are common, not universal, and a lender's overlays beat any published matrix.
