The Quick Read: It depends on the property, not on where you live. The maximum loan is the smaller of two numbers: what the rent can support at the required coverage ratio, and what the leverage cap allows against price or appraised value. Interest-only lifts the first number and leaves the second alone.
- Interest-only drops principal from the payment used in the coverage test, so the same rent supports a larger loan.
- Leverage caps, credit floors, reserves and property rules stay exactly where they were.
- Being out of state does not change the sizing. The file is sized on the property.
- Standard programs run up to $3,000,000, and interest-only structures are available through select lenders in the network.
- The payment steps up when the interest-only period ends, so test the deal on the later payment too.
Why Is There No Single Maximum?
The maximum is a formula result. Rent, the coverage ratio the program requires, the leverage cap, the credit tier and the appraisal all feed it. The smallest loan that satisfies every test is the one you get.

Short-term rental figures are estimates only and vary significantly by season, property type, management approach, and local short-term-rental rules — confirm local regulations before relying on them. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
Most investors hit one of two walls first. Either the rent runs out (the coverage test binds), or the equity runs out (the leverage cap binds). Knowing which wall you hit tells you which lever to pull.
Across the wholesale network, purchase files typically land at 75%-80% LTV on an investment property. Cash-out refinances top out around 75% LTV. Standard programs reach $3,000,000, and balances below the usual minimum route through select lenders. All of this is subject to lender guidelines, and each file is reviewed individually. For the full picture of how these pieces fit together, see the complete DSCR loans guide.
One contrast clears up a common mix-up. Agency conforming limits, which Orrick summarizes at $832,750 for a baseline one-unit loan, do not cap DSCR loans. DSCR loans are business-purpose investor loans, not agency products. That is the only time the conforming number matters here.
Does Being Out of State Change How Much You Can Borrow?
No. Location of the borrower does not enter the sizing math. The lender looks at the property: its rent, its value, its condition and its type. Your home address is not a variable.
What does change on an out-of-state file is how much evidence you need to bring yourself. You are not there to eyeball the street, so the paper has to do the work.
- Rent evidence. Underwriting uses the appraiser’s market rent schedule or the signed lease. On 1-4 unit properties the appraisal includes that schedule. In a market you do not know, a thin rent comp is the usual source of surprises.
- Escrow items. Taxes, insurance and association dues sit in the coverage test. They differ from county to county. Get real quotes before you price the deal, not after.
- Appraisal access. The appraiser needs a way into the property. A tenant, a manager or an agent has to coordinate it.
- Entity documents. If you buy in an LLC, the operating agreement, good standing and ownership documents need to be clean, subject to lender program eligibility.
- Property type. Condos, 2-4 unit buildings, rural parcels and short-term rentals often carry tighter caps than a plain single-family rental.
Some states carry tighter purchase leverage in parts of the network. Connecticut, Florida, Illinois and New Jersey are the ones that come up most often. Treat that as a reason to ask early, not a rule that applies to every lender.
How Does Interest-Only Change the Math?
Interest-only removes principal from the payment in the ratio. The test becomes rent divided by interest, taxes, insurance and dues. A fully amortizing loan uses principal, interest, taxes, insurance and dues instead. Smaller denominator, higher ratio, bigger supportable loan.
Run the numbers on a single property with rent held constant. On an amortizing basis it might test near 0.94x. On an interest-only basis the same rent against the same balance can clear 1.00x. That is the whole mechanism. Nothing about the property changed. Only the payment used in the test changed.
| Factor | Amortizing | Interest-only |
|---|---|---|
| Payment in the ratio | Principal, interest, taxes, insurance, dues | Interest, taxes, insurance, dues |
| Same rent, same balance | Lower ratio | Higher ratio |
| Supportable loan at same ratio | Smaller | Larger |
| Balance during the period | Falls | Stays flat |
| Leverage cap | Unchanged | Unchanged |
| Credit and reserves | Unchanged | Unchanged |
Interest-only structures, along with extended terms such as 40 years, are available through select lenders in the network. The spine of the market is still the 30-year fixed. ARM structures exist for investors who want them, though an adjustable loan can stack a rate reset on top of the principal step-up. The CFPB’s adjustable-rate booklet explains how a longer interest-only period means a bigger later increase.
For a deeper look at sizing without the out-of-state angle, Lendmire’s piece Interest-only DSCR Loan How Much You Can Borrow covers the base case.
How Do You Back Into the Maximum Loan?
Work backward from the rent. Five steps, in order.
1. Fix the rent. Use the appraiser’s market rent or the lease, whichever the program uses. Short-term-rental income is usually reduced before it counts.
2. Divide by the coverage ratio. Rent divided by the required ratio gives the largest total monthly obligation the property can carry. Many select programs start at 1.00. A stronger ratio opens better pricing and leverage.
3. Subtract escrow items. Take out taxes, insurance and association dues. What remains is the most interest the property can carry.
4. Solve for the balance. The remaining interest figure, divided by the annual interest cost per dollar of loan, gives the income-supported balance. The calculator on this site can run this as an illustrative estimate.
5. Apply the leverage cap. Multiply the cap by the lower of purchase price or appraised value. The smaller of the income-supported balance and the leverage-capped balance is your answer.
Say the income-supported balance is higher than the leverage cap allows. Then the cap governs, and the loan can’t rise above it at that price. The real fix there is a higher appraised value or accepting the cap. Interest-only has already done all it can.
Now the opposite case. The leverage cap allows more than the rent supports. Interest-only is the lever that matters, because it raises the income side. This is the file where the structure earns its keep.
What Actually Limits the Number?
Five things limit it, and the tightest one wins. The table lists each with the network’s typical range. Figures are typical guidance, not guarantees, and every file is underwritten individually.
| Constraint | Typical range in the network |
|---|---|
| Coverage ratio | 1.00 is where select programs start; stronger ratios help |
| Purchase leverage | 75%-80% LTV; select high-leverage programs reach 85% with roughly a 700+ score |
| Cash-out leverage | Around 75% LTV, with about 6 months seasoning common |
| Credit | 620 floor in parts of the network; most want about 660; 700+ for top tiers |
| Reserves | About 6 months PITIA; about 9 months above $1,500,000 |
Reserves vary by lender, leverage, loan size and transaction type. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Do not treat any one number as universal.
Coverage below 1.00 is a separate path. It is available through select lenders in the network, with leverage and terms adjusted. No-ratio structures also exist, available only through select lenders, generally for borrowers who already own a primary residence. Both are exceptions, not the default.
A bigger down payment helps, but only so far. It lowers the payment and can lift the ratio. It never erases a credit floor, a reserve rule or a property restriction. The strongest files clear both tests: enough equity and enough rental coverage.
Large loans change the structure options too. Above $2,500,000 the network generally holds to 30-year fixed structures, so interest-only may not be on the table at that size. Ask before you design a deal around it.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
What Happens When the Interest-Only Period Ends?
The payment jumps, and it is not a penalty. It is arithmetic. Nothing was repaid during the interest-only years, so the same balance now amortizes over fewer remaining years.
The OCC’s consumer booklet on interest-only loans says the interest-only period typically runs 3 to 10 years, and that the payment rises even if rates stay flat. Some structures end in a balloon instead.
Here is the stress test that matters. Before you choose interest-only, model the rent against the fully amortizing payment. Picture an investor whose property clears 1.20x on interest-only and tests below 1.00x once principal comes back. That file qualifies today and bleeds later. Either rent has to grow, the balance has to drop through a refinance or sale, or the investor needs cash reserves to carry the gap.
Remember also that DSCR compares rent to the monthly obligation only. Clearing 1.00x is not the same as positive cash flow. Repairs, vacancy, management, utilities and capital expenses all sit outside the calculation. Out of state, where you pay a manager and cannot patch things yourself, those costs deserve real attention.
Equity builds only through appreciation or voluntary principal payments during the interest-only period. Prepayment penalties are also common on investor loans, so ask about them before you plan an early exit.
How Do You Raise Borrowing Capacity?
Pull the levers in this order of usefulness.
- Better rent evidence. A well-supported rent schedule or a signed lease at market moves the numerator.
- Lower escrow items. Shop insurance and confirm tax assumptions. These sit in the denominator.
- Stronger credit tier. Moving from the low 600s to 700+ unlocks higher leverage tiers.
- Structure choice. Interest-only, a longer term or an ARM each lowers the qualifying payment through select lenders.
- More equity. A larger down payment lowers the balance and lifts the ratio, within the caps.
Each one has a cost. Interest-only trades future payment risk for present borrowing power. A longer term trades slower paydown for lower payments. Pick the trade you can live with.
Who Should Choose Interest-Only, and Who Shouldn’t?
| Investor situation | Better fit |
|---|---|
| Deal clears coverage only on interest-only | Test the later payment before committing |
| Plans to hold, rent rising, reserves strong | Interest-only can work |
| Plans a near-term sale or refinance | Interest-only often suits |
| Thin reserves, flat rent market | Amortizing is safer |
| Loan above $2,500,000 | Expect 30-year fixed |
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Some property types are simply not offered. Manufactured homes (single- and double-wide), log homes and barndominiums fall outside these programs.
If you are weighing a line of credit instead of a term loan, Lendmire’s piece DSCR HELOC for Out-of-State Investors and How Much You Can Borrow covers that route.
Frequently Asked Questions
Is there a legal cap on DSCR loan size?
No fixed legal cap applies. Standard programs in the network run up to $3,000,000, and the agency conforming limit does not govern DSCR loans. The practical ceiling is whichever binds first: income support, leverage, credit or reserves. All of it is subject to lender guidelines.
Does interest-only change credit or reserve requirements?
No. It changes the payment used in the ratio and nothing else. Credit tiers, leverage caps and reserve rules stay as they were. Reserves are commonly around 6 months of PITIA, though that varies by file.
Can I use interest-only on a short-term rental?
Often yes, through select lenders, but expect tighter terms. Short-term-rental purchases run up to 75% LTV, with a score of 640 or better and about 12 months of hosting history. Purchases carry a 1.00 coverage floor, and refinances carry a separate floor of their own.
Can I hold the property in an LLC?
Yes, subject to lender program eligibility. Have the operating agreement, good standing certificate and ownership documents ready before the file goes in. Out of state, clean entity paperwork is one of the easiest ways to avoid a stall.
What happens when the interest-only period ends?
The payment rises because the full balance amortizes over fewer years. Model that payment against your rent before you commit, and plan a refinance, a sale or a reserve cushion.
