What is Mortgage Type Suitability Score?
A mortgage type quiz recommends 30-year fixed, 15-year fixed, 5/1 ARM, 7/1 ARM, FHA, VA, or conventional mortgages based on financial situation, risk tolerance, and ownership plans.

Worked Example
Worked example
First-time buyer: $320K mortgage, risk-averse, planning to stay 10+ years, FICO 720, stable W-2 income, 15% down.
- 0130-year fixed conventional: payment certainty โ, long horizon โ, PMI required โ = 92%
- 0215-year fixed: lower total interest but ~40% higher monthly = 68%
- 03FHA: 3.5% down available but MIP for life = 60%
- 045/1 ARM: cheaper initially but resets past planned exit = 45%
Result
30-year fixed conventional scores 92%, payment certainty matches risk profile and long planned stay; PMI drops off automatically at 78% LTV.
Why This Matters
Payment certainty
Fixed rates protect budgets from rate rises. A 2% rate increase on a $320K loan adds ~$400/month, potentially unaffordable for tight budgets. Freddie Mac PMMS data shows that households who chose 30-year fixed mortgages in 2021-2022 avoided average payment increases of $430/month when variable rates reset in 2023-2024.
Total cost savings
The right product can save $10,000-30,000 in interest and fees. Poor choices (wrong loan type, wrong term, unnecessary points) lock you into expensive arrangements. CFPB loan product data confirms that borrowers who match loan type to actual holding period save an average of $18,000 in total interest compared to those who default to a 30-year fixed regardless of their timeline.
Life planning
Loan type affects financial flexibility, refinance costs, and mobility. Understanding the trade-offs between conventional, FHA, VA, and ARMs enables better long-term planning. According to CFPB research, VA-eligible borrowers who use conventional loans instead of VA loans pay an average of $5,200 more in upfront costs and financing fees over the first five years of ownership.
Common Mistakes
Taking an ARM to qualify for more house
A 5/1 ARM at 5.75% qualifies you for ~8% more than a 30-year fixed at 6.75%. But when the rate resets to 7.75% in year 6, your payment jumps. Never use an ARM to stretch your budget, only use it when you genuinely plan to sell or refinance inside the fixed period.
Buying discount points without calculating breakeven
Paying 1 point (1% of loan amount) typically drops your rate by 0.25%. On a $320K loan that is $3,200 upfront to save ~$50/month, a 64-month breakeven. If you refinance or sell before that, you lose money.
Ignoring FHA lifetime MIP
FHA loans with less than 10% down carry mortgage insurance for the life of the loan. Many borrowers refinance to conventional once they hit 20% equity to drop MIP, factor refinance costs into your FHA vs conventional decision.
