Most DSCR lenders draw a hard line somewhere between six hundred sixty and six hundred eighty on credit score. If your middle FICO is below that, your options collapse. That is a problem for investors who have had a rough patch, carry more revolving debt than they used to, or never bothered to rebuild their score because their rental portfolio was cash-flowing fine without it.
The good news is that a credit score of six hundred forty is not the end of the DSCR refinance road. A handful of lenders still refinance investor properties at that score, and the terms are more workable than most investors expect. This is how the program actually works, what you give up at the lower tier, and where you can get the deal done.
Why Most DSCR Lenders Stop at 660 or Higher
DSCR lenders sell their loans into the private-label securitization market. The investors buying those pools prefer paper backed by borrowers with cleaner credit. Setting a six hundred sixty or six hundred eighty floor keeps the pool salable. That is the real reason most DSCR desks will not go lower, not because the loans are unsafe, but because they are harder to sell.
A smaller group of DSCR lenders has appetite for lower-FICO paper, either because they hold the loans on balance sheet or because they have a buyer that accepts a different risk tier. Six hundred forty is the practical floor for this group. Below six hundred forty, your path becomes hard-money or creative financing.
What Changes at a 640 Score
Loan-to-Value
At seven hundred plus, DSCR refinance LTV caps are commonly seventy-five to eighty percent on cash-out and up to eighty-five percent on rate and term. At six hundred forty, expect cash-out LTV to drop to sixty-five or seventy percent and rate-and-term to seventy-five percent. That does not mean you cannot pull equity. It just means you will leave more of it in the deal.
Rate
Rate adjustments for credit scores between six hundred forty and six hundred sixty are usually in the range of zero point five to one percent above the par rate for a seven hundred score. On a four hundred thousand dollar loan, that is meaningful but it is almost always better than paying off the old loan with bridge or hard money.
Reserves
Expect a reserve bump. Most DSCR programs at six hundred forty require six to twelve months of PITI reserves, up from the three to six months typical at seven hundred plus. Liquid assets count. Retirement accounts count at a discounted rate.
Seasoning
Seasoning rules are often stricter for lower-FICO files. You may need six to twelve months of ownership before a cash-out refinance is allowed. Rate and term is usually available immediately.
What the 640 DSCR Refinance Is Actually For
There are three scenarios that come up repeatedly with investors who need a 640-score refinance. The first is the investor who took a credit hit during a business downturn or a personal hardship and has a rental performing well, but the score has not rebuilt yet. The second is the BRRRR operator who bought with hard money, renovated, and needs to refinance out before the hard-money clock runs out. The third is the long-time landlord who ran up credit card balances to fund repairs and now wants to pay them down with equity from one property.
In all three cases, the six-forty DSCR refinance is the bridge. It gets the investor out of expensive short-term capital, locks in long-term financing, and buys time to rebuild credit while the property keeps cash-flowing.
How the DSCR Calculation Works
The debt service coverage ratio is simply the monthly gross rent divided by the monthly PITI, which is principal, interest, taxes, insurance, and any HOA dues. A DSCR of 1.25 means the rent is one hundred twenty-five percent of the payment. A DSCR of 1.00 means rent exactly covers the payment. A DSCR below 1.00 means the property is cash-flow negative before accounting for maintenance and vacancy.
At a 640 score, lenders typically want a DSCR of 1.10 to 1.25 minimum. Some programs allow no-ratio or sub-one DSCR at six forty, with additional rate and LTV adjustments.
Documents You Need Before You Apply
Current lease or a 1007 rent schedule from an appraiser. Two months of bank statements showing reserves. A payoff statement on the existing loan. Proof of insurance that covers the full replacement value and includes the required landlord or dwelling coverage. If the property is in Florida, expect your insurance binder to be the most scrutinized document in the file.
A recent credit report is helpful but not required upfront. The lender will pull a new report during application.
Where 640 DSCR Refinances Actually Get Funded
1. Select Home Loans
Select Home Loans runs DSCR refinances nationwide, including at credit scores as low as six hundred forty. The team works across a handful of DSCR investors, which is the reason the six-forty tier is actually available. A single lender could not keep the program open at that score, but a broker-style shop can price the file against several investors and pick the one that fits.

2. Kiavi
Kiavi is one of the more transparent DSCR lenders and has a published floor that historically includes borrowers around the low six-hundreds. They publish guidelines openly, which makes comparison easy. Pricing at the lowest tier is not always competitive, but the program exists.
3. Visio Lending
Visio Lending focuses almost entirely on rental properties and has been known to approve DSCR refinances at lower credit tiers. Their program is experienced and their underwriting is consistent, which matters for investors who need a clean process.
4. Lima One Capital
Lima One Capital is an investor-focused lender that offers DSCR, fix-and-flip, and new construction products. Their DSCR program has tiers that run into the low six-hundreds and they work well for seasoned investors.
5. Angel Oak Mortgage Solutions
Angel Oak’s DSCR program is part of its broader non-QM platform. Their lower-score tiers are real but often come with rate and LTV adjustments. For borrowers who want a large single lender rather than a broker, they are a reasonable option.
Red Flags That Will Still Kill the Deal at 640
Open bankruptcies, recent foreclosures within the past three to four years, unpaid tax liens, and major judgments will stop even the most flexible DSCR desk. The six hundred forty floor assumes the rest of the profile is clean. If there are other events in the background, the conversation changes and the lender list narrows further.
Severe recent late mortgage payments in the last twelve months are also a major drag. Most lenders want zero or at most one thirty-day late in that window on the subject mortgage.
The Strongest Six-Forty DSCR Profile
The cleanest version of a six-forty DSCR refinance is a borrower with a stable rental that has been leased for at least six months, twelve months of reserves liquid, no recent late payments on the subject property, and a DSCR at or above 1.15. That borrower will be looked at seriously by multiple lenders and will receive competing quotes. If your file is close to that shape, now is the time to move.
