The 620 floor — and the pricing tiers above it
Fannie Mae and Freddie Mac (the two conventional-loan giants) set a hard floor of 620 FICO. Below that, no automated approval is available. From 620 up, conventional prices in tiers — every 20-point credit band changes your rate and PMI premium:
- 620–639: approved, but highest PMI and rate hits
- 660–699: middle-tier pricing
- 700–719: meaningful improvement
- 720–739: near-best pricing
- 740+: best rate and lowest PMI available
- 760+: floor pricing on PMI (as low as 0.15% annually)
How the tiers actually feel in dollars
On a $400,000 loan, moving from 660 to 740 FICO typically saves:
- ~0.25%–0.50% on your rate (about $65–$130/month)
- ~$120–$220/month on PMI at 5% down
Over a 30-year loan, that's $70,000–$120,000 in true cost. If your score is currently 690–720, spending 60–90 days optimizing it before pre-approval is almost always worth it.
First-time-buyer flexibility: HomeReady & Home Possible
Fannie's HomeReady and Freddie's Home Possible programs let low-to-moderate income first-time buyers qualify with reduced MI premiums, non-borrower income counted, and boarder income accepted. Both require a 620+ FICO and completion of a homeownership education course.
If your income is at or below 80% of area median income (AMI), these programs almost always beat standard conventional pricing — sometimes even beating FHA on total monthly cost.
Is this path right for you?
Frequently asked questions
Can I get a conventional loan with a 620 credit score?
Yes — 620 is the Fannie/Freddie floor. Expect the highest PMI and slight rate premium. If you can wait 60–90 days to hit 660–680, the pricing improves materially.
Is 740 really the magic number?
Yes for most conventional pricing grids. 740+ unlocks the best rate tier. 760+ unlocks the lowest PMI floor. Beyond 760, gains are minimal.
What if my score is 640 and I want the best rate?
Consider a rapid-rescore (paying down cards and pulling credit again) — a legitimate way to move 30–50 points in 5–10 business days when balances are the driver.
