The costliest FHA mistakes: buying a home that fails the FHA appraisal, not knowing about lender overlays (620–640), skipping the conventional comparison, forgetting to remove MIP via refinance, opening new credit mid-process, not documenting gift funds, and not checking condo FHA approval. Every one is avoidable with a little planning. See the overview, requirements, and process.

Mistakes before you apply
1. Buying a home that can't pass the FHA appraisal
The #1 FHA-specific mistake. Because the FHA appraisal checks condition — safety, soundness, security — an as-is or fixer-upper home can fail on peeling paint, a bad roof, or exposed wiring. Fix: screen homes for obvious issues before offering, and consider an FHA 203(k) rehab loan for a project house.
2. Not knowing about lender overlays
FHA's floor is 580, but most lenders overlay 620–640. A borrower declined by one lender may wrongly assume FHA is off the table. Fix: work with a broker who knows which lenders actually approve lower scores.
3. Skipping the conventional comparison
FHA's note rate looks lower, but its upfront and lifetime MIP often make it costlier than conventional for good credit. Fix: always run both in real dollars before choosing. See Pros & Cons.
4. Assuming FHA is only for first-time buyers
It's not — repeat buyers qualify too. Fix: don't rule FHA out (or in) based on that myth; check your actual numbers.
5. Not checking condo FHA approval
A condo must be FHA-approved or clear single-unit approval. Buyers fall for a unit, then learn it doesn't qualify. Fix: confirm the project's status before you offer.
Mistakes during the process
6. Opening new credit or making big purchases
A new car loan or furniture on credit raises your DTI and can drop your score mid-process. Fix: buy nothing on credit until you fund.
7. Changing jobs mid-process
An income or job change during underwriting can require re-verification or derail approval. Fix: if a change is coming, tell your loan officer first.
8. Not documenting gift funds
FHA allows 100% gifted down payments — but only if documented with a proper gift letter and paper trail. Fix: get the gift letter and source the funds correctly upfront.
9. Making large undocumented deposits
Big unexplained deposits force underwriters to source the funds and stall the file. Fix: keep money where it is; document anything large; avoid cash deposits.
10. Ignoring closing costs and reserves
Budgeting only for the 3.5% down leaves buyers short at the table. Fix: budget for closing costs too, and ask about seller credits and CalHFA assistance.
Cost & insurance mistakes
11. Forgetting to remove MIP
With under 10% down, FHA MIP lasts the life of the loan — it only ends when you refinance to conventional. Buyers who never plan that refinance overpay for years as California equity builds. Fix: plan the refinance-to-conventional exit from day one and track your equity.
12. Putting just under 10% down
At exactly 10% down, FHA MIP drops off after 11 years instead of lasting the life of the loan. Buyers who land at 8–9% miss that threshold. Fix: if you're close to 10%, ask whether reaching it changes your MIP math.

FHA common-mistake FAQs
What's the most common FHA mistake?
Buying a home that can't pass the FHA appraisal. Because FHA checks condition, an as-is or fixer-upper can fail. Screen before you offer.
Do people overpay by not comparing to conventional?
Yes — FHA's lower note rate plus lifetime MIP often costs more than conventional for good credit. Always run both. See Pros & Cons.
What should I avoid during the process?
New credit, big purchases, job changes, and large money moves. Keep finances stable from application to keys.
Is forgetting MIP removal a mistake?
Yes — under 10% down it lasts the life of the loan unless you refinance to conventional. Plan that exit and track your equity.
What are lender overlays?
Lender minimums stricter than FHA's — often 620–640 vs FHA's 580. A decline from one lender doesn't mean FHA is off the table; a broker finds those that go lower.
