Getting every borrower to 640 for a THDA loan

Why THDA's 640 minimum applies to everyone on a Tennessee loan, how it compares with FHA and local programs, and practical ways to close the gap before you apply.

The quick answer: THDA requires a credit score of at least 640 for every person on the loan, even though FHA alone goes lower. If one spouse is below 640, you can wait and rebuild, ask whether the other spouse can buy alone, or look at local programs with different minimums.

Here's a story I hear a lot. A couple sits down with a lender. She's a Knox County teacher with a 712. He's a paramedic with a 618 after a rough stretch with medical bills. They assume her score carries the file. It doesn't. On a THDA loan, the lowest score in the room is the one that counts.

What the rule actually says

THDA's Great Choice loans, including Homeownership for Heroes, require a credit score of at least 640 for everyone on the loan. It's not an average and it's not just the main borrower. THDA also caps total debt-to-income at 45%.

That's stricter than FHA on its own. FHA's handbook allows maximum financing with a score of 580 or higher, and 500 to 579 with 10% down. So a lender may tell you that you'd qualify for FHA, and that's true. You just wouldn't qualify for FHA with THDA's lower rate and down payment help attached.

How Tennessee programs compare

Program	Credit minimum	Where it works
THDA Great Choice and Homeownership for Heroes	640, every borrower	Statewide
FHA with no state program	580 for 3.5% down	Statewide, any FHA lender
The Housing Fund down payment loan	600 for under $10,000; 620 for $10,000 to $35,000	Statewide
CNE / RockPointBank assistance	660	Hamilton County

The Housing Fund needs an FHA first mortgage and 1% of the price from you, and it isn't clear whether it can sit behind a THDA first mortgage. Still, for a buyer stuck at 615, it's worth a phone call. The program pages are in the assistance directory.

If one of you is under 640

You have three honest paths, and none of them is magic.

1. Wait and rebuild

If you're at 620 or 630, a few months of careful habits can be enough. That's usually the cleanest route because you keep both incomes on the loan.

2. One spouse buys alone

Sometimes the higher-score spouse can qualify on their own income. Two cautions here. First, THDA's income limit looks at the household, so leaving someone off the loan doesn't automatically leave their income out of the limit test. Exactly how THDA counts a non-borrowing spouse is something a THDA-approved lender confirms. Second, both spouses must meet the first-time buyer rule unless you buy in a targeted area or one of you qualifies as a veteran. Our targeted county guide explains where that rule is waived.

3. A different program

If the timing can't wait, plain FHA at 580 or a local program with its own minimum may get you in the door now. You'd give up THDA's rate discount, so compare the monthly cost honestly.

What usually moves a score in a few months

I'm not going to promise numbers, because nobody can. But these are the habits credit counselors talk about most:

Pull all three reports. The free reports the CFPB points people to through AnnualCreditReport.com show what lenders see. Look for accounts that aren't yours or late payments that weren't late.
Dispute real errors with the credit bureau in writing and keep copies.
Bring card balances down. High balances compared with your limits weigh on scores, and paying them down is often the quickest lever.
Stay current on everything. One new late payment while you're preparing can undo months of work.
Hold off on new credit. A new car loan the month before you apply hurts twice: once on your score and once on your debt ratio.
Medical collections: ask the lender how they treat them on your loan type before paying anything off in a hurry.

Free help that's built into the process

Every THDA borrower has to take homebuyer education from a THDA-approved or HUD-approved provider anyway. You can do it as an in-person class or through the eHomeAmerica online course with a one-hour one-on-one session. That one-on-one time is a good place to bring your credit reports. Ask the agency whether it also offers credit counseling, since many HUD-approved counselors do that work too.

Start the class early. If the counselor spots something that needs fixing, you'll want the extra months.

A note on "no score" borrowers

Some people simply don't have a score: they've paid cash for everything. FHA can make loans to borrowers with non-traditional credit through manual underwriting. THDA's rule is written around a 640 score, though, so a borrower without one may not fit a THDA loan. A THDA-approved lender confirms, and if the answer is no, opening a secured card now starts the clock.

A realistic timeline

If one of you is 20 or 30 points short, here's an order of operations that works for a lot of couples. Month one: pull reports, dispute errors and start the homebuyer class. Months two and three: pay down card balances and keep every account current. Month four: ask your lender to pull credit again. If you've made it, get pre-approved and start shopping. If not, you'll at least know exactly where the gap is.

Don't forget the other number

Your score gets you through the door, but THDA's 45% debt-to-income cap decides how much house fits. A paramedic earning $4,800 a month gross could carry about $2,160 in total monthly debts at 45%, house payment included. If a car payment eats $600 of that, the house budget shrinks fast. Try your own figures in the affordability calculator.

Once you think everyone on the loan is at 640 or above, check your eligibility and we'll connect you with a lender who can pull credit and tell you for sure.

Things people ask

Does THDA use the higher score or the lower score?

Every borrower must be at least 640, so in practice the lowest score on the loan decides whether you qualify.

Can I get an FHA loan in Tennessee with a 600 score?

FHA itself allows maximum financing at 580 or higher. You just can't pair it with THDA's Great Choice or Heroes loan until every borrower reaches 640.

Can my spouse stay off the loan so my score counts alone?

Sometimes, if your income qualifies. THDA's income limit is a household test, and both spouses must meet the first-time buyer rule outside targeted areas, so a THDA-approved lender confirms how your case works.

Where can I get credit help in Tennessee?

Start with the THDA- or HUD-approved agency where you take the required homebuyer class. Ask whether it offers credit counseling, and bring your three credit reports to the one-on-one session.
