The Quick Read: A DSCR lender sizes the loan from the replacement property, meaning its appraised value, its rent against the full monthly obligation, and your credit profile. The exchange only decides how much equity you bring and how much debt you need to avoid a tax bill.
- The loan is capped by the tightest of four limits: the lender’s leverage cap, the property’s rent coverage, the loan you actually need after exchange equity goes in, and the tax-driven debt floor from your old loan.
- Exchange equity works as your down payment. It does not rescue a property whose rent is too thin.
- On a purchase of an investment property, most files land at 75%-80% LTV. Select high-leverage programs reach 85% LTV with a score of roughly 700 or higher, subject to lender guidelines.
- Replacing less debt than you paid off can create taxable “mortgage boot.” Extra cash can fill that gap.
- The 45-day identification and 180-day completion deadlines are tax-code rules. They run at the same time, not back to back.
The Four Limits That Set Your Loan Amount
Four separate limits decide your loan amount, and the smallest one wins. Investors often assume the exchange drives the number. It doesn’t. The lender looks at the property you are buying, not the property you sold.

| Limit | What it measures | What moves it |
|---|---|---|
| Leverage cap | Max loan as a % of value | Credit score, property type, program |
| Rent coverage | Rent vs. full monthly obligation | Rent, price, down payment, term |
| Loan you need | Price minus exchange equity and added cash | Sale proceeds, price, cash added |
| Tax debt floor | Old loan payoff you want to replace | Old balance, cash you add |
The first two are lender rules. The third is simple arithmetic. The fourth is a tax goal, not a lender rule. Where the lender’s maximum falls below the debt you want, you have a gap, and you either fill it or live with it.
Which limit binds depends on the deal:
| Your situation | Limit that binds | Usual fix |
|---|---|---|
| Lots of equity, thin rent | Rent coverage | Add cash, pick a stronger-rent property |
| Little equity, strong rent | Leverage cap | Add cash or buy a cheaper property |
| Big old payoff, modest equity | Debt floor vs. cap | Add cash or accept some boot |
Key Terms Defined
DSCR (debt service coverage ratio): the property’s monthly rent divided by its full monthly obligation. A result of 1.25x means rent is 25% above the payment.
PITIA: principal, interest, taxes, insurance, and any association dues. It is the full obligation the rent is measured against.
LTV (loan-to-value): the loan as a percentage of the property’s value, or of the price if that is lower.
Qualified intermediary (QI): the neutral party who holds your sale proceeds so you never touch them. Receiving the money yourself can disqualify the exchange.
Relinquished and replacement property: the property you sell, and the property you buy to continue the exchange.
Boot: anything you receive in an exchange that is not like-kind property, such as leftover cash or reduced debt. Boot is taxable up to the amount of your gain.
How a DSCR Lender Lends on a Like-Kind Exchange, Step by Step
The lender treats your exchange purchase like any other DSCR purchase, with one twist: part of your down payment arrives from the intermediary. Here is the sequence from start to finish.
1. Line up the QI before the sale. The sale proceeds go straight to the intermediary. Your own hands never touch them.
2. The sale closes and both clocks start. NAR summarizes the core rules: 45 days to identify replacement property and 180 days to complete the purchase. Peasebell adds that the 45 days are calendar days, the identification must be in writing, and the two periods run together. You do not get 45 plus 180. The 180 days can also end sooner if your tax return due date, with extensions, comes first. That matters for sales late in the year.
3. Test candidate properties against the coverage math. Take expected rent and divide it by the full obligation. Across our wholesale network, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better leverage and pricing. For the full picture of how these programs fit together, see Lendmire’s complete DSCR loans guide.
4. Order the appraisal and rent schedule. For a single-family home, the appraiser usually completes a rent schedule on form 1007. For two to four units, it is an operating income statement on form 1025. Lenders generally size the loan on the lower of the contract price or the appraised value.
5. Underwriting reviews the property and you. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Your credit still matters. A 620 floor exists in parts of the network, most programs want around 660, and 700 or higher unlocks the strongest leverage. The lender also reviews entity documents and reserves.
6. Funds meet at the title company. The intermediary wires your exchange equity as the down payment. The lender funds the loan. Title disburses both.
7. Report the exchange. You report it on Form 8824 with your tax return. That part belongs to your CPA, not your lender.
Notice what the lender never does. It doesn’t run your exchange, and it doesn’t check your deadlines for you. The QI and your tax adviser handle that side. The lender sizes a loan on a property.
Worked Example One: A Deal That Sizes Cleanly
Run the numbers on a hypothetical, labeled illustrative. You sell a rental and plan to buy a replacement priced at $800,000. Your exchange equity covers about 44% of that price. The loan you need is therefore about 56% of the price, which also happens to match your old payoff.
Compare that to the lender side. On a purchase of an investment property, most files allow 75%-80% LTV. A 56% loan sits well under that cap. Assume the rent on this property clears roughly 1.25x against the full obligation.
Every limit passes:
- The leverage cap has plenty of room.
- Rent coverage clears the 1.00 mark with cushion.
- The new debt matches the old payoff, so there is no mortgage boot.
This is the clean case. Plenty of equity means you borrow modestly, and modest borrowing helps coverage.
Worked Example Two: When Rent Coverage Caps the Loan
Now flip it. You have the equity, but the replacement property’s rent covers only about 0.90x at the loan you need. Here the binding limit is not leverage. It is rent coverage. Your exchange equity can’t fix that.
This catches investors who think a big exchange makes the file strong. It makes the down payment strong. A DSCR file clears both tests: enough equity and enough rental coverage.
Your options look like this:
- Add cash to lower the loan. A larger down payment lowers the monthly obligation and can lift the ratio.
- Pick a stronger-rent property, perhaps a small multifamily where rent sits higher against the price.
- Ask about a sub-1.00 path. That route is available through select lenders in the network, with leverage and terms adjusted. Qualification stays subject to lender guidelines, credit approval, and property review.
One caution. Clearing 1.00 is not the same as positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital costs sit outside it.
Worked Example Three: When the Debt Rule Collides With the Cap
This is the case most investors never see coming. Say your old loan payoff equals 80% of the replacement price, so your exchange equity covers about 20%. The lender caps this purchase at 75% LTV. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Two problems appear at once:
- The lender needs 25% down, but your equity covers only 20%. You must bring about 5% of the price in extra cash.
- The new loan, at 75%, falls below your old payoff of 80%. That shortfall is mortgage boot. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
First Exchange defines mortgage boot as replacement debt lower than relinquished debt, and notes it can arise even if you receive no cash. Here is the good news. 1031exchange.com explains that cash can offset mortgage boot, though new debt cannot offset cash boot. The extra 5% you bring for the lender’s down payment therefore does double duty. It satisfies the lender and fills the debt gap.
Your choices, then:
1. Add the cash and keep the full deferral.
2. Buy a more expensive property so the debt you can borrow reaches your old payoff.
3. Take the smaller loan and accept taxable boot.
Boot does not void the exchange. First Exchange notes that only the boot portion is taxed, up to your gain. Model that tax with your CPA before choosing the smaller loan. Tax treatment varies by situation; consult a qualified tax professional.
What If the Appraisal Comes in Low?
A low appraisal shrinks the loan and enlarges your cash need. The lender generally applies its LTV to the lower of price or appraised value. If the property appraises under contract, the maximum loan drops with it.
Your exchange equity is already committed to the price you agreed on. The gap has to come from somewhere else. Your realistic paths:
- Bring outside cash to cover the difference.
- Renegotiate the price with the seller.
- Order a second look if the appraisal missed relevant comparables.
- Walk away and use another identified property.
This last option only exists if you identified backups in writing within the 45-day window. Consider naming more than one candidate for that reason.
Cash You Need Beyond the Exchange Funds
Exchange funds rarely cover everything. Expect to bring your own money for several items.
Closing costs. Standard transaction costs like commissions and intermediary fees can generally be paid from exchange funds. Other items are murkier. First Exchange notes that using exchange funds for non-qualified expenses, such as insurance premiums, prorated rents, or financing costs, creates boot. Confirm the settlement statement with your QI before closing.
Earnest money. This usually comes from your own account at contract.
Reserves. Reserves are the months of PITIA you must show after closing. They commonly run around six months, and loans above $1,500,000 typically step up to about nine months. They vary by lender, leverage, loan size, and transaction type. Because the intermediary holds the exchange funds until closing, reserves generally come from your own accounts.
Loan sizes run roughly up to $3,000,000 on standard programs. Above $2,500,000, the network generally holds to 30-year fixed structures. For large balances, see Lendmire’s guide to how super jumbo DSCR lenders size loans on small apartment buildings.
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.
Timeline: Pairing the Exchange Clock With Lender Steps
| Milestone | Exchange rule | Lender-side step |
|---|---|---|
| Before the sale | QI engaged | Share the plan, review the file |
| Sale day | Both clocks start | Confirm entity and ownership names |
| Within 45 days | Written identification | Test coverage on each candidate |
| Under contract | Purchase underway | Appraisal, rent schedule, review |
| Exchange deadline | Purchase complete | Funds meet at title |
The 180-day limit is a hard tax-code rule, and a purchase that misses it fails the whole exchange. Peasebell also flags that lenders, title companies, and sellers all add timing risk. The practical fix is preparation. Talk to your broker and QI before the sale closes, and have your entity paperwork, credit, and reserves lined up in advance.
Where the General Rule Bends
Same taxpayer, same name. The party that sells must be the party that buys. DSCR loans commonly close in an LLC, subject to program terms, so a mismatch is a classic trap. An individual sells and a new LLC buys. Whether a single-member LLC solves this is a tax-counsel question. Settle it with your QI and tax adviser before you sign a contract.
Reverse exchanges. Here a parking entity takes title to the replacement property first. Lender appetite for this varies by program, so raise it at the start rather than mid-deal.
Late-year sales. The 180 days can be cut short by your return due date unless you file an extension. Plan around it.
Trading down. Buying a cheaper property is allowed. Unless you add cash, you’ll likely have boot.
Property type. The IRS instructions for Form 8824 limit like-kind treatment to real property held for business or investment, and exclude property held primarily for sale. Flips and dealer inventory don’t qualify on either side. Within real estate, single-family, multifamily, and other investment property are generally treated as like-kind to each other. The lender then applies its own eligibility. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered through these programs.
Multiple replacement properties. You split equity and debt across several purchases, and each loan is sized on its own property.
Short-term rentals. A short-term rental purchase tops out at 75% LTV. Expect a score of 640 or higher, about 12 months of hosting history, and a 1.00 coverage floor on purchases. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Bridge financing. Some investors pair a short-term bridge loan with a later DSCR refinance to meet a tight deadline. That adds risk if the later loan doesn’t come through, so weigh it carefully.
Cash-out after the exchange. A refinance after you own the property is a loan, not exchange proceeds. Cash-out refinances top out around 75% LTV on standard rentals, with about six months of seasoning commonly expected. Your CPA should confirm how a refinance affects the exchange.
What the Decision Looks Like in Practice
Think of it as a short checklist you run for each candidate property:
1. Find the loan you need: price minus exchange equity.
2. Check it against the cap: is that loan within 75%-80% of the lower of price or appraised value?
3. Test the rent: does it cover the full obligation at that loan size with room to spare?
4. Compare to your old payoff: if the new loan is smaller, decide between cash and boot.
5. Count cash beyond the exchange: closing costs, earnest money, reserves.
If any step fails, change the property, the down payment, or the tax plan. Don’t change the story you tell yourself about the numbers.
The strongest exchange buyers walk in with two or three pre-tested candidates and a settled entity structure. That preparation, more than any single program feature, keeps the 180-day period workable.
Frequently Asked Questions
Does exchange equity count toward DSCR lender review?
It counts toward the down payment, not toward coverage. A DSCR lender measures rent against the full obligation on the loan you take. A thin-rent property stays thin no matter how much equity you bring, although a bigger down payment lowers the loan and can lift the ratio.
Do I have to replace my old loan with an equal new loan?
No. You can replace debt with debt or with added cash. What you can’t do is offset cash you received with new debt. If your new loan is smaller than your old payoff, the difference is mortgage boot unless you add cash.
What if I want to buy a cheaper property?
You can, but expect boot unless you add cash to cover the lower debt. The tax is limited to your gain. Ask your CPA to model both options before you commit.
Can the lender run my 1031 exchange?
No. The intermediary and your tax adviser run the exchange. The lender reviews the property’s rental income and funds the loan. Keep them informed of the dates so the file lines up with your deadlines.
Can I pull cash out right after buying?
Possibly later, though it is a separate question from the exchange. Talk with your CPA about how a refinance affects your exchange before you plan one.
