FHA vs Conventional Loan With 20% Down: Which Is Better in 2026?
Invalid Date
Quick Answer
If you have a 20% down payment and a credit score of 680 or higher, a conventional loan is almost always cheaper than an FHA loan in 2026. The biggest reason: conventional loans eliminate PMI entirely at 20% down, while FHA loans still charge both upfront MIP (1.75%) and annual MIP regardless of down payment size. On a $400,000 home, choosing conventional over FHA with 20% down can save you $40,000+ over the life of the loan. FHA only wins if your credit score is below 680 or you need flexible income/DTI qualification.
Key Takeaways
- Conventional eliminates PMI at 20% down — the single biggest cost difference between the two loan types.
- FHA charges MIP no matter what — 1.75% upfront + 0.15%–0.55% annually, even with 50% down.
- Total 30-year savings of $40,000–$55,000 when choosing conventional over FHA with 20% down on a typical home.
- FHA rates are less credit-sensitive — below 680 credit, FHA may actually offer a lower rate despite the MIP.
- Refinancing is the only escape from FHA MIP — with 20% down, plan to refinance into conventional after 6–12 months if rates allow.
- Conventional offers better investment property terms — with 20% down, conventional allows investment properties and second homes; FHA does not.
Why 20% Down Changes the FHA vs Conventional Math
Most FHA vs conventional comparisons assume a 3.5% to 5% down payment, where FHA’s lower down payment requirement and flexible credit standards give it a clear advantage for cash-strapped buyers. But when you bring 20% down to the table, the calculation shifts dramatically.
The PMI/MIP Crossover
At 20% down, conventional loans automatically eliminate private mortgage insurance (PMI). This is not negotiable — it is a feature of conventional lending. Once your loan-to-value (LTV) ratio hits 80%, PMI disappears.
FHA loans work differently. FHA mortgage insurance premium (MIP) is mandatory regardless of down payment amount. Even if you put down 50%, you still pay:
| FHA MIP Component | Cost | When It Applies |
|---|---|---|
| Upfront MIP | 1.75% of loan amount | Paid at closing (can be financed) |
| Annual MIP (30-year, >$625k) | 0.55% of loan amount | Paid monthly for 11 years (if ≥10% down) |
| Annual MIP (30-year, ≤$625k) | 0.15%–0.50% of loan amount | Paid monthly for 11 years (if ≥10% down) |
Real Dollar Comparison on a $400,000 Home
Let’s say you are buying a $400,000 home with 20% down ($80,000). Your loan amount is $320,000.
FHA Loan Costs (20% Down):
- Upfront MIP: $5,600 (1.75% × $320,000) — usually financed into the loan
- Annual MIP: ~$1,440/year ($120/month) at 0.45% rate for 11 years
- Total MIP cost over 11 years: ~$21,440 ($5,600 + $15,840)
- If financed, upfront MIP accrues interest over 30 years: additional ~$5,800
Conventional Loan Costs (20% Down):
- Upfront PMI: $0
- Monthly PMI: $0
- Total mortgage insurance cost: $0
Difference: $21,440+ in mortgage insurance alone, and that does not account for the typically higher FHA interest rates.
Detailed Cost Comparison: FHA vs Conventional With 20% Down
Here is a side-by-side breakdown for a $400,000 home purchase with 20% down ($80,000), assuming a 720 credit score and a 30-year fixed-rate mortgage in mid-2026.
Scenario A: Credit Score 720 (Strong Credit)
| Factor | FHA Loan | Conventional Loan |
|---|---|---|
| Loan amount | $325,600 ($320k + $5,600 UFMIP) | $320,000 |
| Interest rate | ~6.875% | ~6.500% |
| Monthly P&I | ~$2,143 | ~$2,023 |
| Monthly MIP/PMI | ~$122 (for 11 years) | $0 |
| Total monthly payment | ~$2,265 | ~$2,023 |
| Monthly savings (conv) | — | $242/month |
| 30-year total cost difference | — | ~$47,000 saved |
Scenario B: Credit Score 640 (Lower Credit)
| Factor | FHA Loan | Conventional Loan |
|---|---|---|
| Loan amount | $325,600 | $320,000 |
| Interest rate | ~7.000% | ~7.500% (rate hit for low credit) |
| Monthly P&I | ~$2,162 | ~$2,239 |
| Monthly MIP/PMI | ~$122 | $0 |
| Total monthly payment | ~$2,284 | ~$2,239 |
| Monthly savings (conv) | — | $45/month |
| 30-year total cost difference | — | ~$12,000 saved (conv still wins, but margin shrinks) |
Scenario C: Credit Score 600 (Very Low Credit)
| Factor | FHA Loan | Conventional Loan |
|---|---|---|
| Loan amount | $325,600 | May not qualify |
| Interest rate | ~7.125% | ~8.000%+ (if approved) |
| Monthly P&I | ~$2,190 | ~$2,347 |
| Monthly MIP/PMI | ~$122 | $0 |
| Total monthly payment | ~$2,312 | ~$2,347 |
| Monthly savings (FHA) | $35/month | — |
In this scenario, FHA actually wins because conventional rates spike significantly below 620 credit.
When FHA With 20% Down Actually Makes Sense
Despite the conventional advantage at 20% down, there are specific situations where FHA is the better choice:
1. Credit Score Below 680
FHA interest rates are less sensitive to credit score changes than conventional rates. If your score is in the 580–679 range, the conventional rate hit (often 0.5%–1.0% higher) combined with possible lender overlays can make FHA cheaper overall despite the MIP.
2. High Debt-to-Income Ratio (Above 45%)
FHA allows DTI ratios up to 56.99% with compensating factors (per HUD Handbook 4000.1), while most conventional lenders cap at 50% and prefer 43% or lower. If your DTI is high, FHA may be the only option even with 20% down.
3. Non-Traditional Credit History
If you lack a traditional credit score (no credit cards, no loans) but have a strong 20% down payment saved through cash, FHA allows non-traditional credit verification using rent, utility, and insurance payment history. Conventional loans rarely accommodate this.
4. Recent Credit Events (Bankruptcy, Foreclosure, Short Sale)
FHA has shorter waiting periods:
- Chapter 7 Bankruptcy: 2 years (FHA) vs 4 years (conventional)
- Foreclosure: 3 years (FHA) vs 7 years (conventional)
- Short Sale: 3 years (FHA) vs 4 years (conventional)
If you are within these windows, FHA may be your only viable option.
5. You Plan to Refinance Within 2–3 Years
If you expect your credit to improve or rates to drop, starting with FHA and refinancing to conventional later can be a strategic move. You would pay MIP for the short term, then eliminate it via refinancing once you qualify for conventional pricing.
The Refinance Exit Strategy
For borrowers who choose FHA with 20% down (usually due to credit), the refinance exit strategy is critical:
- Monitor your credit score — Once it crosses 680, conventional refinancing becomes attractive.
- Wait for rate dips — Even a 0.25% rate drop can make refinancing worthwhile.
- Calculate break-even — Refinancing costs (~$3,000–$5,000) should be recovered within 12–18 months of monthly savings.
- Request a new appraisal — If your home has appreciated, your LTV will be even stronger for conventional refinancing.
Example: You buy with FHA at 7.0% with a 640 credit score. Eighteen months later, your score is 700 and rates have dipped to 6.25%. Refinancing to conventional eliminates MIP ($122/month), secures a lower rate, and saves you ~$300/month total. Break-even on $4,000 in closing costs: 13 months.
How 20% Down Affects Other Loan Features
Interest Rate Pricing
Conventional lenders offer their best rates at 80% LTV (20% down). This is because loans at or below 80% LTV carry significantly lower default risk. You may see rate improvements of 0.125%–0.375% compared to a 95% LTV conventional loan.
FHA rates are relatively flat across down payment amounts. Putting 20% down on an FHA loan does not meaningfully improve your rate compared to putting 3.5% down.
Loan Limits
With 20% down, you can afford more expensive homes, but each loan type has different limits:
- FHA loan limits (2026): Up to $1,149,825 in high-cost areas; $524,225 in standard areas
- Conventional conforming limits (2026): $806,500 in standard areas; $1,209,750 in high-cost areas
- Jumbo loans: Above conventional limits, 20% down is often a minimum requirement
If you are buying a higher-priced home, conventional conforming and jumbo loan limits are more generous than FHA limits in most markets.
Property Type Flexibility
With 20% down, conventional loans allow you to finance:
- Primary residences
- Second homes (vacation properties)
- Investment properties (1–4 units)
- Condominiums (including non-warrantable condos with some lenders)
FHA with 20% down is restricted to:
- Primary residences only
- No second homes or investment properties
- FHA-approved condo projects only
This is a significant advantage for conventional if you are considering house hacking or buying a vacation home.
Cash Reserves and Qualifying
Both loan types benefit from the stronger financial position that 20% down demonstrates, but conventional lenders may offer:
- Reduced reserve requirements (2 months vs 6 months)
- More flexible gift fund rules
- Expanded eligibility for non-occupant co-borrowers
Step-by-Step: Choosing Between FHA and Conventional With 20% Down
Step 1: Check Your Credit Score
- 740+: Conventional is almost certainly better. You will get the best rates and zero PMI.
- 680–739: Conventional is still better. Rate advantage + no PMI = significant savings.
- 620–679: Compare offers. Conventional likely still wins, but the gap narrows.
- 580–619: FHA is likely better. Conventional rates spike and approvals become harder.
- Below 580: FHA only. Most conventional lenders will not approve.
Step 2: Calculate Total Cost of Ownership
Do not just compare monthly payments. Factor in:
- Upfront MIP/PMI costs
- Monthly mortgage insurance
- Interest rate differences over the full term
- Tax implications (MIP and PMI are both deductible in 2026 if income is below phaseout limits)

Step 3: Evaluate Your 5-Year Plan
- Staying 5+ years? Conventional’s savings compound — the longer you stay, the more you save.
- Moving in 3–5 years? The upfront MIP on FHA makes it expensive for short holding periods.
- Planning to renovate? An FHA 203(k) loan could be worth the MIP if you need renovation financing.
Step 4: Get Pre-Approved for Both
Request Loan Estimates (LE) from lenders for both FHA and conventional. The standardized LE format makes side-by-side comparison easy. Focus on:
- Section A (origination charges)
- Section B (services you cannot shop for)
- Section C (services you can shop for)
- Line H (monthly MIP/PMI)
- Page 3 (total cost over 5 years)
Step 5: Choose and Lock
Once you have both offers, the math usually makes the decision obvious. If conventional is cheaper by $100+/month, choose conventional. If the difference is under $50/month, consider other factors like property type flexibility and future refinancing plans.
Common Myths About 20% Down and FHA Loans
Myth 1: “20% down removes FHA mortgage insurance”
False. FHA loans require MIP regardless of down payment. Only after 11 years (with ≥10% down) can MIP be removed, and only on loans originated after June 3, 2013.
Myth 2: “FHA offers lower rates than conventional”
Generally false. FHA rates are sometimes quoted lower, but when you factor in the upfront MIP and monthly MIP, the effective rate is higher. FHA rates appear competitive because they are less credit-sensitive, not because they are inherently lower.
Myth 3: “You should never put 20% down on an FHA loan”
Mostly true, but with exceptions. For most borrowers, putting 20% down on a conventional loan is the better financial choice. However, borrowers with credit scores below 680, high DTI, or recent credit events may benefit from FHA despite the MIP.
Myth 4: “Conventional loans require 20% down”
False. Conventional loans require as little as 3% down (Fannie Mae HomeReady, Freddie Mac Home Possible) or 5% down (standard conventional). The 20% threshold simply eliminates PMI — it is not a minimum requirement.

The Bottom Line
Having 20% down puts you in a strong financial position, and in most cases, a conventional loan maximizes that advantage. The elimination of PMI alone saves tens of thousands of dollars over the life of the loan, and conventional rates at 80% LTV are typically 0.25%–0.50% lower than FHA rates.
Choose FHA with 20% down only if:
- Your credit score is below 680 and conventional rates are uncompetitive
- Your DTI exceeds conventional limits
- You have recent credit events within conventional waiting periods
- You need non-traditional income or credit verification
For everyone else with 20% down and decent credit, conventional is the clear winner. Take the money you would have spent on MIP and invest it, save it, or use it for home improvements that build equity.
