You sit down with a lender, share your income and down payment, and within ten minutes they're walking you through an FHA loan like it's the only option on the menu. The pitch usually leans on one thing: the rate is lower than conventional.
That part is often true. FHA almost always quotes a lower interest rate than a comparable conventional loan. What the pitch leaves out is everything else attached to that rate, and for buyers with decent or good credit, the rest of the math usually points the other direction.
Why FHA's rate looks better at first glance
FHA loans are insured by the federal government, which lets lenders price the rate aggressively. It's normal to see FHA quoted a quarter to half a point below conventional on the same day. That's a real difference, and on the surface it looks like a clear win.
The reason that gap exists is the mortgage insurance the government collects in exchange. FHA's lower rate isn't a gift. It's a discount funded by two separate insurance charges that the borrower carries for the life of the loan. Once you put both of those next to the rate savings, the picture changes for most buyers.
The two costs FHA adds that conventional doesn't
The first is the upfront mortgage insurance premium, sometimes called the funding fee. It's 1.75% of your loan amount, financed into the balance at closing. On a $400,000 loan, that's $7,000 added to what you owe before you've made a single payment. Conventional loans have no equivalent charge.
The second is the monthly mortgage insurance premium. On most modern FHA loans, it runs about 0.55% of the loan amount per year and stays on the loan for as long as you keep it. The only way to get rid of FHA's monthly MIP is to refinance into a different loan or sell the home.
Conventional loans use private mortgage insurance, or PMI, when you put less than 20% down. Two things make conventional PMI structurally different from FHA's MIP. First, the rate is tied to your credit score, so strong credit gets cheap PMI. Second, it falls off automatically once you reach 78% loan-to-value, and you can request removal at 80%. After that, your payment drops and stays dropped.
How credit score flips the math
This is the part most lenders gloss over. Conventional PMI is priced on a sliding scale based on your credit score. The better your score, the cheaper the insurance.
At a 620 score, conventional PMI runs higher than FHA's MIP, and FHA's lower rate carries the day. At 680, the two get close. By 720 and up, conventional PMI drops well below FHA's 0.55%, and the small interest rate advantage FHA offers can't make up the gap.
FHA's mortgage insurance, by contrast, doesn't care about your credit. A 760 borrower pays the same MIP as a 620 borrower. That's the whole point of a federally backed program, and it's also why strong-credit borrowers effectively subsidize weaker ones inside FHA.
The funding fee compounds the problem
Even when FHA's monthly cost ends up close to conventional, the upfront 1.75% funding fee is permanent damage to your equity position. On that same $400,000 loan, you start with $7,000 less equity than a conventional buyer who put down the same cash.
Three or five years down the road, when you go to sell or refinance, you carry that gap with you. Conventional buyers in Davidson, Williamson, and Rutherford counties who held their loan through a few years of normal appreciation often find themselves at 20% equity faster than they expected. At that point their PMI drops, their payment falls, and the loan starts looking very different from the one they signed.
An FHA borrower in the same house, with the same appreciation, is still paying MIP. The funding fee is still baked into the balance. The only way out is a refinance, which costs money and depends on rates being friendly when you're ready to move.
When FHA is genuinely the right call
FHA isn't a bad product. It's a specific product, designed for specific buyers, and when it fits, it fits well.
If you're in any of those buckets, FHA's flexibility is doing real work. The lower rate plus easier underwriting is the actual benefit of the program, and it shows up in your monthly payment.
The buyer who gets quietly hurt by an FHA recommendation
It's the buyer with a 720 or 740 credit score, steady income, and 5 to 10% to put down, who never gets shown a real comparison. The lower headline rate looks attractive, qualifying is easy, and the MIP doesn't seem like a big deal at the time of application.
Five years later, that buyer is sitting on a loan with mortgage insurance that won't drop off, the funding fee still built into their balance, and a payment running $150 to $250 a month higher than a conventional borrower who looked otherwise identical to them on paper. Over the typical hold period for a starter home in Middle Tennessee, it adds up to thousands in lost equity and cash flow.

What to ask before you sign anything
If your lender quoted you FHA without volunteering a comparison, three questions will surface what you need to know.
What's the conventional rate and PMI at my exact credit score and down payment? Not a generic estimate. The actual number tied to your file.
What's my total monthly payment under each loan, and where do they cross over once PMI drops on the conventional? That's the chart that tells you which loan actually wins over your expected hold period.
How much equity will I have after three years on each loan, including the FHA funding fee? That's the question almost no one asks, and it's the one that exposes how much the upfront FHA cost really matters.
A lender willing to walk through all three answers in plain language is a lender doing the job correctly. If you're getting hand-waves instead of numbers, get a second opinion before you sign.
