Mortgage Pre-Approval at 680 FICO: Conventional Sweet Spot
680 is the second-best execution tier in the Fannie Mae LLPA matrix. At 680, conventional pricing finally beats FHA decisively, PMI drops to a meaningful discount over MIP, and the credit conversation shifts from program selection to optimisation. This page walks through the program math, the 680 vs 740 question, and where HomeReady fits.
All figures as of May 2026. Rate assumptions from the Freddie Mac Primary Mortgage Market Survey.
Quick Answer at 680 FICO
Conventional, 10% down, $90K income, $0 debts: $360,000-$385,000 pre-approval
Rate quoted: ~6.75% (vs 6.50% at 740)
Assumes conventional 30-year, 0.80% PMI, 1.1% property tax, $1,500/yr insurance. As of May 2026.
Why 680 Beats Both 620 and FHA
The LLPA matrix steps down meaningfully at 680. At 620-639 FICO with 90 percent LTV, the LLPA is 2.625 points. At 680-699 with the same LTV, it falls to 1.000 points. That 1.625-point drop equates to roughly 0.40 percent in rate, or $96 a month on a $300,000 loan ($34,560 over the life of the loan). The full LLPA waterfall is the largest single driver of conventional pricing in this credit band.
PMI also gets cheaper. Standard conventional PMI at 680 prices around 0.70-0.90 percent annual (vs 1.10-1.40 percent at 620). On a $300K loan with 10 percent down, that saves another $100-$125 a month. Combined with the LLPA improvement, the 60-point lift from 620 to 680 is worth roughly $200-$220 a month in lifetime carrying cost.
FHA at 680 still works but no longer wins. FHA MIP is fixed at 0.55 percent annual regardless of credit, so high-credit borrowers subsidise lower-credit borrowers within the FHA pool. The break-even between FHA and conventional sits around 680-700, and conventional dominates above that.
Program Stack at 680: What to Pick
First choice: Conventional 5-10% down
Default at 680 for most buyers. 5 percent down avoids the steepest LLPA bracket (97 percent LTV adds 0.25 points), gets PMI to 0.70-0.90 percent annual, and lets you cancel PMI at 80 percent LTV (achieved through amortisation in roughly 8-10 years, faster with appreciation). Rate quote: ~6.75 percent. PMI cancels and your payment drops by $200-$240 a month around year 10.
Second choice: HomeReady or Home Possible (if income ≤80% AMI)
If your household income is at or below 80 percent of the area median for the property location, HomeReady (Fannie) or Home Possible (Freddie) waives the area-median LLPA, caps total LLPA at 1.500 points, allows 3 percent down, and prices PMI around 0.85 percent annual. The combined savings vs standard conventional at 680 is roughly $80-$100 a month on a $300K loan.
Niche option: FHA only if very high DTI
FHA at 680 makes sense only if you need the 50 percent back-end DTI ceiling (vs 45 percent on conventional DU Accept). At high DTI, the FHA program tolerance opens approval that conventional would refer. The premium cost is roughly $80-$120 a month vs conventional, which is the price you pay for the wider DTI box.
Veterans: VA if eligible
Per the VA Lenders Handbook (Pamphlet 26-7), VA loans require no down payment, no monthly mortgage insurance, and price competitively with conventional at 680. Funding fee is 2.15 percent first use (waived for service-connected disability). VA is the dominant choice at 680 for any eligible borrower.
Income-Scenario Pre-Approval Estimates at 680
Conventional 30-year purchase loan, 10 percent down, 6.75 percent rate, 1.1 percent property tax, $1,500/yr insurance, 0.80 percent annual PMI, 45 percent back-end DTI ceiling.
| Income | Monthly Gross | DTI Budget | Max Loan | Max Home Price |
|---|---|---|---|---|
| $60,000 | $5,000 | $2,250 | $255,000 | $283,000 |
| $80,000 | $6,667 | $3,000 | $345,000 | $383,000 |
| $100,000 | $8,333 | $3,750 | $435,000 | $483,000 |
| $120,000 | $10,000 | $4,500 | $525,000 | $583,000 |
| $150,000 | $12,500 | $5,625 | $660,000 | $733,000 |
Assumes no other monthly debts. Each $500 of existing monthly debt reduces max home price by roughly $60,000-$80,000.
Should You Push to 740?
From 680 to 740 the LLPA drops another 0.625 points and PMI drops another 0.20 percent annual. On a $400K loan that combination is worth roughly $90-$110 a month, or $32,000-$40,000 over a 30-year term. The 60-point lift typically takes 4-8 months for someone already at 680, because the easy wins (utilisation, dispute) often happened on the way to 680.
The 680-to-740 lift is dominated by time-based factors: age of accounts, length of credit history, and the natural ageing of any late marks. There is no fast lever once you are at 680 with clean current behaviour.
If you are buying in a rising market where prices move 0.5-1.0 percent a month, waiting for 740 can cost more in home-price appreciation than it saves in rate. Run the math both ways before deciding. At 680 with conventional pricing already in your favour, locking in usually beats waiting.
Frequently Asked Questions
Is conventional better than FHA at 680?
Yes, in almost every scenario. At 680, conventional LLPAs drop by 1.375 points vs the 620-639 band, which cuts the rate spread to PMMS to roughly +0.25 percent (vs +0.65 percent at 620). Conventional PMI at 680 prices around 0.70-0.90 percent annual, well below the FHA 0.55 percent MIP plus 1.75 percent upfront. The lifetime advantage of conventional at 680 is typically $8,000-$12,000 over 10 years.
How much house can I afford at 680 with $90K income?
On $90,000 gross income, 680 FICO, conventional 10 percent down, no other monthly debts, and a rate around 6.70 percent, expect $360,000 to $385,000 in maximum pre-approval. With 5 percent down (HomeReady at 80 percent AMI), the range stretches a touch on price (lower down payment) but the qualifying payment is similar. With $500 a month in existing debts, lop $50,000-$60,000 off both numbers.
Can I get a jumbo loan at 680?
Possibly, but tight. Most jumbo investors require 700+ FICO; a handful (Bank of America's wealth-management channel, some credit unions, portfolio lenders) accept 680 with strong reserves and 20-25 percent down. Pricing at 680 jumbo is typically 0.50-0.75 percent above conforming, vs 0.25-0.50 percent at 740. If you are within reach of 700, waiting 30-60 days is usually worth it for jumbo.
What is the cost difference vs 740 at this tier?
On a 30-year conventional purchase loan, 680 quotes roughly 0.25 percent above 740. On a $400K loan that is about $63 a month, or $22,680 over the life of the loan. Worth chasing if you can pick up the 60-point lift in 90-180 days through utilisation and dispute work. Less compelling if it requires more than six months or significant credit drama.
Will my PMI cancel automatically at 680?
Yes. Under the federal Homeowners Protection Act (12 USC 4901), PMI cancels automatically when the loan amortises to 78 percent of the original property value on the original payment schedule, regardless of credit score. You can request cancellation at 80 percent LTV based on current value, with the lender requiring a documented appraisal (usually $500-$700). Both cancellations are unaffected by credit at the cancellation date.
Can I qualify for HomeReady at 680?
Yes, with the AMI eligibility test. HomeReady requires income at or below 80 percent of area median income for the property location (no income limit in low-income census tracts). Look up your AMI on the Fannie Mae HomeReady eligibility tool. At 680 FICO and qualifying AMI, HomeReady delivers reduced PMI (around 0.85 percent annual), waived area-median LLPA, and 3 percent down. The combination saves roughly $1,800-$2,400 a year vs standard conventional at the same FICO.
Does a 680 score get me the best rate?
No, but it gets close. The biggest rate breaks are at 660 (one credit-tier shift), 680 (LLPA waterfall), 720 (conforming best-execution tier at most investors), and 740 (LLPA matrix bottom). 680 is the second-best execution point in the matrix. Pushing to 740 saves about $60-$80 a month on a $400K loan; pushing past 740 (760, 780, 800) is rate-neutral on most investor sheets.
