Conventional Opens, LLPAs, PMI Cancellation, FHA vs Conv at 620
Mortgage with 620 Credit Score: What Opens Up at the Conventional Threshold
620 is the conventional eligibility threshold — the score where Fannie Mae’s Desktop Underwriter can issue an Approve/Eligible finding. Below 620, conventional is off the table entirely. At 620, you unlock cancellable PMI, higher conforming loan limits ($832,750 vs FHA’s $541,287 floor), and a path to eliminate permanent mortgage insurance. But the LLPAs at 620 add significant rate premium — compare total cost against FHA carefully.

What Opens at 620
- Conventional eligibility: DU can approve at 620 — the hard floor for all Fannie Mae and Freddie Mac conventional products
- Cancellable PMI: Conventional PMI cancels at 78% LTV automatically — FHA MIP is permanent on most loans, costing tens of thousands more
- Higher loan limits: Conventional conforming at $832,750 vs FHA floor at $541,287 — matters in mid-cost markets between those amounts
- Action: At 620, run both FHA and conventional through AUS — the cheaper program depends on your holding period and down payment
The LLPA Problem at 620
- Rate penalty: LLPAs at 620 add approximately 1.0–1.25% to the base rate compared to a 740+ borrower on the same LTV
- PMI premium: PMI rates at 620 are significantly higher than at 680+ — adding $50–$100/month more than optimal PMI pricing
- FHA may win short-term: FHA’s lower rate (no LLPAs) often beats conventional at 620 for holding periods under 7–8 years
- Action: Compare total monthly cost (PI + MI/MIP) AND total 5-year cost between FHA and conventional at your exact score and LTV
FHA vs Conventional at 620
- FHA advantage: Lower rate (no LLPAs), higher DTI ceiling (56.99% vs 45–50%), and lower monthly payment in years 1–7 typically
- Conv advantage: PMI cancels at 78% LTV — FHA MIP is permanent. Over 10+ years, conventional saves $15,000–$30,000+ in total MI cost
- Break-even: FHA is cheaper for the first 7–8 years. Conventional wins from year 8+ when PMI drops off and FHA MIP continues
- Action: If selling or refinancing within 7 years: FHA may be cheaper total. If keeping 10+ years: conventional wins decisively
Next Steps from 620
- Improve to 680: Drops LLPAs significantly — saves $75–$125/month through better rate and PMI pricing on a $300K loan
- Improve to 740: Best available pricing tier — minimal LLPAs, lowest PMI rates, maximum lender competition on pricing
- HomeReady/Home Possible: Income-limited conventional programs at 620 with reduced PMI and 3% down for eligible borrowers
- Action: 620 gets you in the door but 680+ gets you competitive pricing — continue credit work even after qualifying at 620

The Bottom Line Up Front
620 is the conventional eligibility threshold — the score where Desktop Underwriter can issue an Approve/Eligible finding and you gain access to Fannie Mae and Freddie Mac conventional loan products. Below 620, conventional is completely unavailable. At 620, you unlock cancellable PMI (the single biggest advantage over FHA), higher conforming loan limits, and additional program options like HomeReady and Home Possible.
The catch: loan-level pricing adjustments at 620 add approximately 1.0–1.25% to your interest rate compared to optimal 740+ pricing. PMI rates are also at their highest tier at 620. This means FHA — with no LLPAs and a lower base rate — is often cheaper on a monthly basis for the first 7–8 years of the loan. Conventional overtakes FHA when PMI cancels at 78% LTV (approximately year 8–10 at standard amortization) while FHA MIP continues permanently. Your expected holding period determines which program is actually cheaper over your ownership timeline.
What Exactly Changes at the 620 Threshold?
The transition from 619 to 620 opens an entirely new tier of mortgage products. Below 620, your options are limited to FHA (580+ for 3.5% down), VA loan program (if eligible), and USDA (manual underwriting at limited lenders). At 620, conventional conforming loans become available — and with them, a fundamentally different mortgage insurance structure that can save tens of thousands over the loan’s life.
What 620 Unlocks
- Conventional conforming loans: Fannie Mae and Freddie Mac products through Desktop Underwriter and Loan Product Advisor — the standard conventional mortgage pathway used by the majority of U.S. homebuyers
- Cancellable PMI: Conventional private mortgage insurance cancels automatically at 78% LTV and by borrower request at 80% LTV. FHA MIP is permanent on loans with less than 10% down. This single difference can save $30,000–$50,000 over a 30-year loan
- Higher loan limits: Conventional conforming limit is $832,750 (2026 baseline) versus FHA’s floor of $541,287. For homes priced between $541,287 and $832,750, conventional at 620 may be the only non-jumbo option available
- HomeReady and Home Possible: Income-limited conventional programs with reduced PMI rates and 3% down payment for borrowers at or below 80% of area median income — lower cost than standard conventional at the same score level
- Conventional refinance access: Rate-term and cash-out conventional refinance both become available at 620. This is the path for FHA borrowers to eliminate permanent MIP by refinancing into conventional once they reach 620+ credit and 20% equity
Deal Saver
If you are at 610–619, the 1–10 point improvement to reach 620 is the second most valuable credit threshold crossing in mortgage lending (after the 580 FHA threshold). Paying one revolving card below 10% utilization and requesting a rapid rescore can cross this threshold in days — opening conventional eligibility, cancellable PMI, and higher loan limits. The lifetime value of crossing 620 on a $300,000 loan exceeds $30,000 in PMI savings alone versus staying in FHA permanently.
How Do Loan-Level Price Adjustments Affect Your Rate at 620?
Loan-level pricing adjustments are the mechanism Fannie Mae and Freddie Mac use to price risk into conventional mortgage rates. LLPAs are percentage-point additions to the base rate that vary by credit score and LTV ratio. At 620, LLPAs are at their highest level — adding approximately 1.0–1.25% to the rate compared to a 740+ borrower at the same LTV.
The LLPA penalty decreases in steps as credit scores improve. At 640–659, the penalty drops by approximately 0.25–0.375%. At 660–679, another 0.25% reduction. At 680+, the penalty drops significantly — this is the score level where conventional pricing becomes genuinely competitive. At 740+, LLPAs are minimal and the borrower receives the best available conventional rate. Each 20-point improvement from 620 produces a measurable rate reduction that translates to real monthly savings.
| Score | Approx LLPA Rate Addition (95% LTV) | Monthly Impact ($300K) | PMI Rate Range |
|---|---|---|---|
| 620–639 | +1.25% | +$250/mo vs 740+ | 1.0–1.5% |
| 640–659 | +0.875% | +$175/mo vs 740+ | 0.8–1.2% |
| 660–679 | +0.625% | +$125/mo vs 740+ | 0.5–0.9% |
| 680–699 | +0.375% | +$75/mo vs 740+ | 0.35–0.6% |
| 700–719 | +0.25% | +$50/mo vs 740+ | 0.25–0.45% |
| 720–739 | +0.125% | +$25/mo vs 740+ | 0.20–0.35% |
| 740+ | Baseline | Best rate | 0.15–0.30% |
Is FHA or Conventional Better at 620?
This is the critical comparison at 620 — and the answer depends entirely on how long you plan to keep the loan. FHA has no LLPAs, resulting in a lower base rate at 620 than conventional. FHA also has higher DTI tolerance (56.99% vs 45–50%) which helps borderline qualifiers. But FHA’s permanent MIP costs 0.55% annually for the life of the loan — a cost conventional eliminates through PMI cancellation at 78% LTV.
On a $350,000 purchase with 5% down at 620: FHA typically costs $100–$140 less per month than conventional during the first 7–8 years because of the lower rate and no LLPA penalties. But from approximately year 8 onward — when conventional PMI cancels — conventional saves $150–$200/month because FHA MIP continues while conventional PMI is gone. Over a full 30-year term, conventional saves $30,000–$50,000 more than FHA despite the higher monthly cost in the early years.
The break-even point: if you plan to sell, refinance, or move within 7 years, FHA’s lower monthly cost during those years may make it the cheaper total option. If you plan to keep the loan beyond 8 years, conventional is definitively cheaper because PMI cancellation eliminates the insurance cost entirely while FHA MIP continues accruing. Run both scenarios through AUS and compare the total cost at your specific expected holding period — not just the monthly payment in year one.
Lender Reality Check
Many loan officers default to FHA at 620 because FHA files are simpler to process and the lower rate makes the monthly payment look better on the initial quote. But they rarely show the 10-year or 30-year total cost comparison that reveals conventional’s PMI cancellation advantage. Ask for both quotes with a side-by-side comparison showing total cost at 5, 10, and 30 years. If the loan officer cannot or will not produce this comparison, find one who will — the difference in lifetime cost is too significant to ignore.
What Is the Best Strategy at 620?
The optimal strategy at 620 depends on three factors: how long you plan to keep the loan, how quickly your credit can improve further, and whether your DTI requires FHA’s higher ceiling to qualify at all.
Strategy by Situation
- Keeping 10+ years, DTI under 45%: Choose conventional. The higher initial cost is more than offset by PMI cancellation savings starting around year 8. Continue improving credit to 680+ for a future refinance at better LLPA pricing — this captures both the PMI cancellation benefit and improved rate pricing
- Selling or refinancing within 5–7 years: FHA may be cheaper total because you exit before the PMI cancellation break-even point. Calculate both scenarios at your actual expected timeline. If FHA saves $100/month for 5 years ($6,000 total) versus conventional’s long-term advantage, FHA wins the short-hold math
- DTI above 45%: FHA may be your only option because TOTAL Scorecard approves DTI up to 56.99% while conventional DU typically caps at 45–50%. If you need the DTI stretch to qualify, the FHA vs conventional comparison is moot — FHA is the only program that will approve the file
- Improve to 680 before applying: If credit simulation shows 680 is achievable in 60–90 days through utilization reduction, waiting produces the best outcome — conventional pricing at 680 is dramatically better than at 620, with LLPA penalties dropping by approximately 0.875% and PMI rates falling by 40–50%
File Guidance
At 620, you are at the bottom of conventional pricing. Every 20-point improvement from here produces measurable monthly savings. Before applying at 620, ask your lender for a credit simulation: what would the rate and PMI cost be at 640? At 660? At 680? If the simulation shows 660 or 680 is achievable through $3,000–$5,000 in card paydowns, the 60–90 day credit work investment saves you $75–$125/month on the eventual loan — paying back the paydown investment within the first year of homeownership. The math at 620 strongly favors additional improvement when it is achievable within a reasonable timeline.
The Bottom Line
620 opens conventional eligibility — the most important threshold after 580 because it unlocks cancellable PMI, higher loan limits, and a fundamentally different mortgage insurance structure than FHA. But LLPA penalties at 620 are steep, making conventional more expensive than FHA in the first 7–8 years. The break-even favors conventional for holdings beyond 8 years when PMI cancels.
Compare both programs at your expected holding period — not just the year-one monthly payment. If you are within 40–60 points of 680 (the optimal conventional pricing tier), invest in credit work before applying. Every 20-point improvement from 620 saves $50–$75/month in rate and PMI combined. The credit improvement cost is a fraction of the lifetime savings on a 30-year mortgage. And remember: qualifying at 620 is the starting point, not the end goal. Continue building credit toward 680+ even after closing — a conventional refinance at better pricing captures the improvement retroactively.
Frequently Asked Questions
Can I get 3% down conventional at 620?
Yes — through HomeReady (Fannie Mae) or Home Possible (Freddie Mac) if your income is at or below 80% of area median income. Standard conventional requires 5% minimum at most lenders. The 3% programs also offer reduced PMI rates compared to standard conventional at 620, making them the best conventional option when income-eligible.
When does conventional PMI cancel at 620?
Automatically at 78% LTV based on the original amortization schedule — typically around year 8–10 on a 30-year loan with 5% down. You can request cancellation earlier at 80% LTV if you can demonstrate the value through a new appraisal or BPO. PMI rates at 620 are higher than at 680+, making the cancellation savings even more significant.
Do all lenders offer conventional at 620?
Most do — 620 is the standard DU minimum with no overlay at many institutions. Some lenders overlay at 640 or 660 on conventional. If a lender declines you at 620 for conventional, their overlay is higher than the DU minimum. Shop a different lender or use a broker to find one that follows DU’s 620 floor without additional credit overlay.
How fast can I go from 620 to 680?
60–90 days for utilization-driven improvement. Paying revolving balances below 10% can add 30–50 points within one billing cycle. Combined with error corrections and rapid rescore, a 620-to-680 gain is achievable in 2–3 months for many borrowers. If the low score is driven by recent late payments rather than utilization, the timeline extends to 6–12 months for seasoning.
Does the 620 threshold apply to refinances?
Yes — conventional rate-term and cash-out refinances both require 620 minimum for DU approval. If you currently have an FHA loan and want to refinance into conventional to eliminate MIP, you need 620+ credit plus sufficient equity (ideally 20%+ to avoid PMI entirely). This is the standard FHA exit strategy.
Is 620 enough for a jumbo loan?
No. Most jumbo lenders require 700+ minimum with 10–20% down payment. Jumbo loans above the $832,750 conforming limit have separate and stricter credit requirements than conforming conventional. At 620, your options are limited to conforming conventional and government programs.
