Conventional Home Loan Guide 2026: Requirements & Rates
Photo by Tima Miroshnichenko on Pexels
Conventional loans are the largest single segment of the U.S. mortgage market — roughly 70% of purchase originations in 2026 — and they remain the default choice for buyers with solid credit and a real down payment. The category covers conforming loans (those that fit Fannie Mae and Freddie Mac guidelines) plus jumbo loans (those that exceed them). The pricing is rate-driven, the rules are well-understood, and PMI — unlike FHA’s lifetime MIP — actually goes away.
We pulled the 2026 Fannie Mae Selling Guide and Freddie Mac Single-Family Seller/Servicer Guide updates, surveyed conventional pricing across 14 lenders, and ran scenario math for 3%, 5%, 10%, and 20% down. This guide explains what conventional really means in 2026, when it beats FHA/VA/USDA, and exactly what you need to qualify.
How This Guide Works
We focus on conforming conventional loans — those at or below the 2026 baseline limit of $806,500 in most counties (up to $1,209,750 in high-cost areas). Jumbo conventional pricing and rules are covered separately in Jumbo Mortgage Rates 2026.

|---|---|---|

2. Down Payment Options
Conventional financing is the most flexible category on down payment:
- 3% down — Conventional 97 (first-time buyers), HomeReady, Home Possible
- 5% down — Standard conforming
- 10% – 19% down — Lower PMI factors
- 20%+ down — No PMI required
Gift funds are allowed from family on primary residences. 5% must be your own funds on second homes.
3. Private Mortgage Insurance (PMI)
PMI is required whenever you have less than 20% down on a conventional loan. Unlike FHA’s lifetime MIP, conventional PMI:
- Automatically cancels at 78% LTV based on original amortization schedule
- Can be requested removed at 80% LTV with proof of value
- Is priced based on credit score and LTV
2026 monthly PMI estimates on a $400,000 loan:
| FICO | 5% Down | 10% Down | 15% Down |
|---|---|---|---|
| 760+ | $107 | $73 | $40 |
| 720 – 759 | $148 | $97 | $54 |
| 680 – 719 | $233 | $147 | $80 |
| 660 – 679 | $322 | $200 | $107 |
4. Debt-to-Income Limits
Standard maximum DTI on a conforming conventional is 45%, with extensions to 50% allowed by automated underwriting (Desktop Underwriter / Loan Product Advisor) when reserves, credit score, and residual income are strong.
5. Property Eligibility
Conventional financing works on the broadest range of properties:
- Primary residence (1–4 unit)
- Second home (1 unit)
- Investment property (1–4 unit)
- Most condominiums (warrantable)
- Most planned-unit developments
- Manufactured homes (with restrictions)
6. Reserves Requirement
“Reserves” means liquid funds left after closing, measured in months of PITI (principal + interest + taxes + insurance). Typical 2026 requirements:
- Primary residence: 0–2 months
- Second home: 2–4 months
- Investment property: 6 months
- Multiple financed properties: Up to 12 months

How to Choose Conventional Over FHA / VA / USDA
- You have 720+ credit. Conventional pricing breaks favorably above 720 FICO compared to FHA’s flat MIP penalty.
- You can put 5% or more down. PMI on 5% down is meaningfully cheaper than FHA MIP.
- You want PMI to disappear. Conventional PMI cancels; FHA MIP stays for the life of most loans.
- You’re buying a second home or investment. FHA, VA, and USDA all require owner occupancy; conventional doesn’t.
- You’re financing above the FHA county limit. High-priced markets often push the loan amount over FHA’s ceiling, leaving conventional or jumbo as the only options.

Final Verdict
Conventional is the right call when your credit is 720+, your down payment is 5% or higher, and you want PMI to actually disappear as you build equity. It’s also the only path for second homes and investment properties. Below 680 FICO or under 5% down, FHA usually wins on month-one cost. Above those thresholds, conventional almost always wins on lifetime cost — get quotes on both and compare the all-in monthly numbers, not just the rate.
