FHA or Conventional? In Idaho, the Right Answer Comes Down to One Number.
There is a question almost every Treasure Valley buyer has asked at some point.
"Should I go FHA or conventional?"
And the honest answer is: it depends on one number sitting in your credit report.
Pick the wrong loan type and the difference in mortgage insurance alone can add up to tens of thousands of dollars over time.
Not because the rate is bad.
Because FHA mortgage insurance can last for the full loan term, while conventional PMI can usually be removed once enough equity is reached.
What Is the Difference Between FHA and Conventional Loans?
An FHA loan is backed by the federal government and lets you buy with as little as 3.5% down and a credit score as low as 580.
A conventional loan is privately backed and typically requires a 620 credit score or higher, with a down payment of 3% to 20%.
Neither is better than the other.
They are designed for different buyers at different stages of their financial lives.
FHA was created after the Great Depression to help more Americans become homeowners.
Because the federal government insures the loan, lenders take less risk.
That lower risk is what allows FHA to offer easier entry requirements than conventional.
Think of FHA as the door with a lower entry bar. Conventional is the door that often costs less once you are inside.
The Mortgage Insurance That Leaves and the One That Stays
If you put less than 10% down on an FHA loan, you pay mortgage insurance for the life of the loan.
It does not go away when your home value goes up.
It does not go away when you have paid down 30% of the balance.
It stays until you sell or refinance into a different loan.
With a conventional loan, the mortgage insurance (called PMI, or private mortgage insurance) can usually be removed once you reach 20% equity based on the home's original value, and it must automatically terminate at 78% of the original value if your payments are current.
Here is a simple way to picture this.
Imagine two gym memberships.
One charges you every month forever, no matter how fit you get or how often you go.
The other charges you until you hit your goal weight, then cancels on its own.
FHA mortgage insurance is the first one.
PMI is the second.
FHA mortgage insurance never cancels on its own. PMI does.
On a $400,000 home in Idaho with 3.5% down, the FHA mortgage insurance looks like this.
You pay a one-time upfront fee of $6,755 (rolled into the loan balance).
Then you pay $177 every month on top of your regular payment.
That is $2,124 per year.
And it does not stop.
Most buyers focus on the down payment. The fee that shapes the long-term cost is the monthly insurance.
What Do These Numbers Look Like on a Real Treasure Valley Home?
On a $400,000 Treasure Valley home, an FHA buyer at 3.5% down pays $14,000 upfront and $177 per month in insurance that never expires.
A conventional buyer at 5% down pays $20,000 upfront and a PMI that disappears as their equity grows.
Here is the part that surprises most buyers.
Conventional PMI is not the same for every person.
It is based on your credit score.
And that single fact changes the entire comparison.
Take a buyer with a 720 or higher credit score.
At 5% down on that same $400,000 home, their monthly PMI runs roughly $170 to $190.
That PMI can usually be removed once they hit 20% equity.
FHA insurance on the same home is $177 per month and never leaves.
Now take a buyer with a 640 credit score.
Their conventional PMI at 5% down jumps to roughly $300 to $370 per month.
Their FHA insurance is still flat at $177.
For a buyer with a 640 credit score, FHA is often the cheaper loan by $125 or more every single month.
Same loan type.
Different credit profile.
Completely different answer.
Which Loan Makes More Sense for Idaho Buyers?
If your credit score is above 720, conventional is usually the better long-term choice.
Your PMI will be low, and it goes away when you build equity.
If your score falls in the high-500s to upper-600s, FHA can often be more accessible and may produce a lower monthly payment than conventional, depending on your lender's pricing and your full financial profile.
You have probably heard the personal finance advice: put 20% down, go conventional, get a 15-year mortgage.
That advice is not wrong.
Dave Ramsey has built an entire career around it, and the math holds up if you have the cash.
Here is the problem for Idaho buyers.
Based on the latest Treasure Valley market data, the median home in Meridian is around $525,000.
Twenty percent down on that home is $105,000 sitting in savings before you buy a single thing.
For most first-time Idaho buyers, that is a 7 to 10 year wait while rent keeps climbing.
FHA exists for exactly this gap.
You can get in with $14,000 to $18,000 down, start building equity right away, and still grow real wealth as a homeowner.
There is also a strategy some buyers use on purpose.
They buy with FHA, let the home appreciate, and refinance to conventional once they have 20% equity.
In Idaho, where home values have risen steadily over the last decade, some buyers have hit that mark faster than they expected.
When that happens, the monthly insurance goes away and they often lock in a better rate at the same time.
The key is knowing your plan before you pick your loan.

Four Questions Worth Asking Your Lender Before You Decide
Before choosing FHA or conventional in Idaho, ask your lender to run both scenarios with your actual credit score, the home price you are targeting, and your planned down payment.
That side-by-side comparison will make the right answer clear faster than any article can.
Here are four questions worth having ready before that conversation.
What will my PMI rate be at my current credit score?
How long before I could realistically reach 20% equity based on current values in this area?
What rate are you quoting me for FHA versus conventional right now?
Is the home I want to buy under the 2026 FHA loan limit for Ada or Canyon County? In Ada and Canyon Counties, the 2026 FHA 1-unit limit is $586,500. That last question matters more than people expect.
Above $586,500 in Ada or Canyon County, FHA is simply not available.
The conventional conforming limit is $832,750 here, which covers nearly all non-luxury purchases in the Treasure Valley.
The right answer is not in a Google article. It is in the spreadsheet your lender builds with your actual numbers.

Quick Recap
FHA: 3.5% down, 580+ credit, mortgage insurance stays for the life of the loan (if under 10% down)
Conventional: 3-20% down, 620+ credit, PMI can be removed at 20% equity (original value) and must auto-terminate at 78%
720+ credit score: Conventional usually wins long-term
High-500s to upper-600s credit score: FHA can be more accessible and often produces a lower monthly payment
Always ask your lender to run both scenarios with your real numbers
