The Default Answer Is Usually Wrong
Most first-time CT buyers hear two things: FHA requires only 3.5% down, and conventional loans require 20% to avoid mortgage insurance. Both of those statements are true and both are misleading in ways that cost buyers real money.
Conventional loans don't require 20% down. They go as low as 3% down with private mortgage insurance. And FHA's mortgage insurance isn't the cheap option it sounds like, especially for buyers who have decent credit scores and stay in the home for more than five or six years.
The right loan depends on your credit score, your down payment, how long you plan to stay, and in CT, something that often gets missed: the property you're buying. FHA has property condition requirements that can eliminate entire categories of homes from FHA-eligible purchases. In a state with as much older housing stock as Connecticut, that matters.
What the Credit Score Threshold Actually Means
FHA loans are available to borrowers with credit scores as low as 580 (with 3.5% down) or even 500 (with 10% down). Conventional loans typically require a minimum score around 620, with pricing that improves substantially as the score rises above 700 and 740.
For buyers with credit scores below 660, FHA often wins on rate and availability. The conventional market gets more expensive for borrowers with lower scores - mortgage insurance gets pricier, and rate adjustments add up.
For buyers with credit scores above 700 or 720, the calculation flips. Conventional PMI for a borrower with a 740 score and 10% down is often meaningfully less expensive than FHA mortgage insurance - and conventional PMI cancels automatically when you reach 80% loan-to-value (roughly when you've paid down 20% equity). FHA mortgage insurance on loans originated after June 2013 lasts for the life of the loan if you put down less than 10%. The only way to remove it is to refinance into a conventional loan.
That's a significant long-term cost difference that doesn't show up in the monthly payment comparison your lender shows you at origination.
The Property Condition Issue in CT
FHA appraisals are stricter than conventional appraisals. An FHA-approved appraiser doesn't just assess value - they assess property condition against minimum property standards. Things that a conventional appraiser would note but not require action on can become required repairs in an FHA appraisal.
Common FHA appraisal flags in Connecticut's older housing stock: peeling or deteriorated paint (especially important in pre-1978 homes due to lead paint requirements), damaged roofing, exposed wiring, broken or missing handrails, inoperable windows, structural issues, and significantly deteriorated exterior components.
When an FHA appraiser flags something as a required repair, the seller must fix it before the loan can close - or the buyer has to make other arrangements. In a competitive CT offer situation, some sellers specifically exclude FHA offers because they don't want the additional appraisal conditions hanging over the transaction. That's legal, and it's more common than most buyers realize.
If you're shopping for homes that are older, need cosmetic work, or are in less-than-perfect condition - and a lot of affordable CT homes fall into that category - FHA's property requirements may narrow your buyer pool significantly.
The Down Payment Math in Connecticut
FHA requires 3.5% down (with a 580+ credit score). A 3% conventional option also exists through programs like Fannie Mae's HomeReady or Freddie Mac's Home Possible, which are designed for first-time buyers and have income limits.
On a $350,000 purchase, 3% is $10,500 and 3.5% is $12,250. The difference is relatively small. The difference in monthly mortgage insurance is larger and persists much longer.
Connecticut also has state programs through CHFA (Connecticut Housing Finance Authority) that provide down payment assistance and below-market rate mortgages to eligible buyers. These programs work alongside both FHA and conventional financing. If you qualify for CHFA assistance, factor that into your comparison - the CHFA rate and the assistance structure may shift which loan type makes the most sense.
Worth knowing: Connecticut also offers a forgivable $25,000 down payment assistance program through Time to Own for eligible buyers. That amount of assistance changes the math on down payment significantly and may eliminate the need for the low down payment that makes FHA attractive in the first place.
How to Make the Decision
Get pre-approved for both if you qualify for both. A good lender will run the numbers side-by-side: rate, monthly payment including mortgage insurance, closing costs, and a 7-year total cost comparison. The 7-year horizon matters because it accounts for how long you'll pay mortgage insurance and whether you're likely to refinance or sell before the conventional PMI cancels automatically.
The questions to answer before choosing:
What is your credit score? Below 660, FHA often wins on rate. Above 720, conventional is usually better long-term.
How long do you expect to stay? FHA's permanent mortgage insurance is less painful if you're refinancing in 3-4 years anyway.
What homes are you looking at? If the homes you're considering have condition issues that might not pass FHA, conventional eliminates that friction.
Do you qualify for CHFA or Time to Own assistance? If yes, factor those programs into the comparison with your specific numbers.
Basically, don't let any single piece of advice - including this one - make the decision for you. Run the actual numbers with a CT lender who has done both loan types many times. The right answer is specific to your credit, your purchase price, and the homes you're looking at.
Bottom line: FHA wins on accessibility when credit scores are lower or the down payment is very limited. Conventional often wins on total long-term cost for buyers with scores above 700. In Connecticut's older housing market, FHA's stricter property requirements are a real factor in which homes you can finance — and which offers sellers will consider.
Frequently Asked Questions
What credit score do I need for an FHA loan in Connecticut?
FHA loans are available with credit scores as low as 580 with a 3.5% down payment, or as low as 500 with 10% down. Most FHA lenders in Connecticut have overlays — meaning they set their own minimum (often 620 or 640) above the FHA minimum. For the best FHA rates and terms, aim for 660 or higher.
Do FHA loans require mortgage insurance in Connecticut?
Yes. FHA loans require both an upfront mortgage insurance premium (1.75% of the loan amount, typically rolled into the loan) and an annual mortgage insurance premium paid monthly. For loans with less than 10% down originated after June 2013, FHA mortgage insurance lasts for the life of the loan. The only way to remove it is to refinance into a conventional loan once you have enough equity.
Can CT sellers refuse FHA offers?
Yes, sellers can decline any offer for any legal reason, including the financing type. Some CT sellers in competitive markets prefer conventional or cash offers because FHA appraisals have stricter property condition requirements that can create additional repair demands before closing. If you're making an FHA offer in a competitive situation, be aware that some sellers may weight it differently than a comparable conventional offer.
What is the FHA loan limit in Connecticut for 2026?
FHA loan limits are set by county and updated annually by HUD. Connecticut counties have different limits — Fairfield County, being a high-cost area, has higher limits than Hartford County and other inland counties. Check the current HUD loan limit lookup tool for your specific county before assuming FHA will cover your target purchase price. In higher-priced areas like coastal Fairfield County, buyers may find the FHA limit is below what they need to borrow.
