The Quick Read: A DSCR refinance pays off your existing first mortgage and writes a new first mortgage, so you cannot keep a locked-in first loan and refinance it at once. The new loan has to pass two tests: enough equity for the leverage cap, and enough rent to cover the new payment. Keeping the old first means borrowing behind it instead.
- Only the new loan’s payment counts in the coverage math on a refinance. The old payment disappears.
- Cash-out refinances on investment property top out around 75% LTV across most of the network, with about 6 months of seasoning common.
- Coverage of 1.00 is where select programs start, and stronger ratios open better pricing and leverage.
- Passing coverage is not the same as positive cash flow.
- A second lien can protect the old first, but it adds a second payment to the coverage test. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
The Core Rule: A Refinance Replaces, It Does Not Add
A refinance is a swap. The new lender pays off the old first lien and takes first position. The old loan’s terms are gone for the entire balance, not just the part you wanted to borrow against.

That matters more now than it used to. Wolf Street’s analysis of federal mortgage data found that 49.9% of outstanding mortgages sit in its two lowest-cost tiers. Those figures cover all mortgaged homes, not only rentals, but many investors are holding one of those loans.
So the real question is not whether a DSCR refinance is possible. It is which part of your debt you are willing to reprice. The full refinance reprices all of it. A second lien reprices only the new dollars. For a wider view of how these loans work, see the complete DSCR loans guide.
How Underwriting Treats the Refinance, Step by Step
Here is the sequence the file follows across most programs in the wholesale network Lendmire works with.
1. Choose the structure. Replace the first, or leave it alone and add a second lien. Everything after depends on this choice.
2. Order the appraisal with a rent schedule. The appraiser reports both value and market rent. Fannie Mae’s Selling Guide lists Form 1007 as the rent schedule exhibit for one-unit homes. Its forms page lists Form 1025 for small two-to-four-unit properties. DSCR loans are not agency loans. Those are just the standard form names.
3. Pick the rent figure. Many lenders credit the lower of your in-place lease and the appraiser’s market rent. Your own projection never sets the number.
4. Compute coverage. Monthly rent divided by the full monthly obligation on the new loan: principal, interest, taxes, insurance, and any association dues. That obligation is called PITIA.
5. Run the value test. The new loan amount is measured against the appraised value, called LTV.
6. Clear the other gates. Credit score, reserves, seasoning, property eligibility, a payoff statement for the old first, and entity papers if the home sits in an LLC (subject to lender program eligibility).
Two tests, and the tighter one controls. Strong equity cannot rescue weak rent. Strong rent cannot rescue a loan that is too large for the value.
Requirements at a Glance
This table reflects typical ranges from select lenders in the network. Every file is underwritten individually, and these are not commitments to lend.
| Requirement | What the lender checks | Typical range |
|---|---|---|
| Coverage | Rent vs. full PITIA | 1.00 is where select programs start |
| Cash-out leverage | LTV on the new appraisal | Up to about 75% on investment property |
| Rate-and-term leverage | LTV on the new appraisal | Select tiers reach up to 85% |
| Credit | Score tier | 620 floor in parts; most want about 660 |
| Strongest tiers | Score for top leverage | 700+ |
| Reserves | Liquid cash after closing | About 6 months PITIA; about 9 above $1.5M |
| Seasoning | Time you have owned it | About 6 months common for cash-out |
| Loan size | Balance requested | Up to $3,000,000 on standard programs |
A few notes on that table. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Above $2,500,000, the network generally holds to 30-year fixed structures. Credit tiers also shift pricing, not just eligibility.
A Worked Example
These are modeled assumptions, not market data. Say a rental covers its old first mortgage at roughly 1.6x. That is a comfortable cushion, and the investor feels rich on paper.
Now refinance the whole balance into a new first. The new payment is larger because the old loan’s terms vanish. Coverage on the new loan may land near 1.2x. Still clears 1.00.
Add a cash-out draw on top. The balance grows, the payment grows, and coverage slides toward 1.0x or just under it. At that point the file is no longer a plain 1.00 program deal. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted, but it is a different path with different pricing.
The lesson: a property can cash-flow beautifully on the old loan and still stumble on the refinance. Pre-check coverage on the new payment, not the old one.
Can You Keep the Low First? The Second-Lien Route
Yes, but not through a refinance. You borrow behind the first with a closed-end second, which is a fixed-amount loan with its own payment. Scotsman Guide’s non-QM coverage describes this as a way to pull equity without giving up the low first, and notes that closed-end seconds tend to carry lower closing costs.
The underwriting changes in three ways:
- Combined coverage. Rent is divided by both payments. The second adds to the denominator on day one.
- Combined LTV. All liens are measured against value. The first loan’s balance counts. Its low cost does not help the ratio.
- Documents. Expect to provide the first-lien mortgage statement.
Lendmire’s piece How to Buy a Second Home by Cash-Out Refinance With a Low First Mortgage walks through the equity side. Here is the side-by-side.
| Factor | Replace the first | Keep first, add second |
|---|---|---|
| Old loan terms | Gone | Preserved |
| What gets repriced | Entire balance | New dollars only |
| Coverage counts | New payment only | Both payments |
| Best for | Larger cash needs, LLC title, long hold | Smaller needs |
Availability matters too. Fewer lenders write rental-qualified seconds than write first liens, so the option exists but the menu is thin. A broker who sees many programs earns their keep here.
Can a Home You Live In Qualify?
Not while you live in it. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
If you moved out and now rent the home, the file may be reviewable as a rental, subject to lender guidelines. The appraisal’s market rent and your lease history do the talking. If you still sleep there, this is the wrong product.
Where the General Rule Breaks
Condos. Association dues sit inside PITIA, so identical rent produces a lower ratio than on a house. The building also gets a project review.
Short-term rentals. There are no leases to compare, so income is documented differently, typically with a rental analysis or about 12 months of hosting history. Leverage is tighter. A short-term-rental cash-out tops out around 70% LTV, while a standard long-term rental cash-out reaches about 75%. A short-term-rental purchase goes to 75% LTV and a refinance runs around 70%. Expect a 640+ score and a 1.00 coverage floor on purchases and on refinances. 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.
Interest-only structures. Select lenders offer interest-only periods, and coverage is then measured on interest, taxes, insurance, and dues without the principal. That flatters the ratio. Never compare an interest-only ratio to a fully amortizing one.
Longer terms. The spine is the 30-year fixed. A 40-year term and ARM structures exist through select lenders for investors who want them.
Rehab exits. If a short-term rehab loan is being taken out by a DSCR loan, that is a refinance too. The new appraisal sets value and market rent. Your after-repair estimate is only a planning number.
Subordination. If you add a second now and later refinance the first, the second lienholder must agree to stay behind the new loan. It has no obligation to. Decide early whether a future refinance is likely.
Title. Some second-lien products prefer personal or trust title, while many first-lien DSCR programs allow an LLC, subject to program terms.
Ineligible homes. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network’s DSCR programs.
One more trap: prepayment charges on the old loan reduce your net proceeds and push out your break-even. Read the existing note before you plan.
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.
If Coverage Falls Short
You have levers. Try them in this order.
1. Draw less cash. A smaller loan means a smaller payment.
2. Document stronger rent. A solid lease or a better rent schedule can lift the number the lender credits.
3. Pay down principal first. A larger down payment, or a paydown before the refinance, lowers the payment and can lift the ratio.
4. Choose a different structure. An interest-only period or a longer term through select lenders may change the math.
5. Use a lower-coverage path. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. No-ratio qualification is available only through select lenders, generally for borrowers who already own a primary residence.
Equity and coverage are separate hurdles. A bigger down payment never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests.
Is It Worth It?
It depends on three things: the size of your need, how long you will hold, and how the home is titled.
A longer hold spreads the one-time cost of replacing the old first over more years. A large cash need, or LLC ownership, favors the refinance. A small need on a personally titled home often favors keeping the first and adding a second.
Compare total cost, not just the new payment. Include closing costs, any prepayment charge on the old loan, and the loss of the old loan’s terms on the entire balance.
One caution. Clearing 1.00 does not mean the property cash-flows. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. Budget for them separately.
Key Terms Defined
DSCR (debt service coverage ratio): Monthly rent divided by the full monthly loan obligation, used to judge whether the property supports the loan.
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly cost of the loan.
LTV: Loan-to-value, the new loan balance divided by the appraised value.
CLTV: Combined loan-to-value, which measures all liens against value, used when a second is added.
Seasoning: The ownership period a lender wants before it lends against current value.
Rate-and-term refinance: A refinance that changes the loan’s terms without taking out extra cash.
Cash-out refinance: A refinance for more than the old payoff, with the difference paid to you.
Frequently Asked Questions
Can I refinance and keep my low first mortgage?
No. A refinance replaces the first lien. To keep the old loan, you borrow behind it with a second lien, and the combined coverage and combined LTV then apply. Availability of rent-qualified seconds is thinner than for first liens.
Does DSCR look at my old payment?
No. On a refinance, only the new loan’s PITIA counts. On a second lien, both payments count. That is why a property that covered easily before can fall short after replacing the first.
What credit score do I need?
A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. All of this is subject to lender guidelines and individual underwriting.
Which rent does the lender use?
Many lenders credit the lower of your lease and the appraiser’s market rent, from the rent schedule on the appraisal. Short-term rentals are documented with a rental analysis or hosting history instead of leases.
Is the refinance worth it if my current loan is so cheap?
Often not on a small cash need, because you reprice the whole balance to raise a little equity. A larger need, LLC title, or a long hold can tip it the other way. Run both structures before deciding.
