How Does Mortgage Rate Estimation Work?
Credit Score Tiers
Lenders tier rates by FICO: 760+ (best), 740-759, 720-739, 700-719, 680-699, and below. Each tier may add 0.125-0.25%.
Loan-to-Value (LTV)
LTV = loan amount ÷ home value. Above 80% (less than 20% down) often triggers rate adjustments or PMI.
Loan Type & Market
Conforming, jumbo, FHA, and VA loans have different rate structures. Market rates follow the 10-year Treasury yield.

Frequently Asked Questions
What determines my mortgage rate?
Lenders use credit score, loan-to-value ratio (LTV), loan type, property type, and market conditions. A 760+ FICO typically qualifies for the best rates, while scores below 680 may add 0.5% or more. Freddie Mac PMMS tracks average 30-year fixed rates weekly.
How does my credit score affect my mortgage rate?
Each 20-point drop below 760 can add roughly 0.125-0.25% to your rate. A 680 score vs 760 may mean a 0.5% higher rate—on a $300K loan that's about $90 more per month. Improving your score before applying can save thousands.
What is a rate lock and when should I use it?
A rate lock guarantees your interest rate for a set period (typically 30-60 days) while you complete the loan process. Lock when you're satisfied with the rate and within 30 days of closing. Longer locks (60-90 days) often cost 0.125-0.25% more.
How do ARM and fixed-rate factors differ?
Fixed-rate mortgages are priced on Treasury yields and your credit profile. ARMs add factors like the index (SOFR, LIBOR), margin, and caps. In rising rate environments, fixed rates may be more attractive; ARMs can save money if you plan to move within 5-7 years.
Should I buy points to lower my rate?
One discount point (1% of loan amount) typically reduces your rate by 0.25%. On a $300K loan, that's $3,000 for ~$50/month savings. Break-even is usually 5-7 years—buy points only if you plan to stay that long.
What are current mortgage rate trends?
Rates follow the 10-year Treasury yield and Fed policy. In 2024, the average 30-year fixed hovered around 6.5%. Check Freddie Mac PMMS and Bankrate for weekly updates. Rates can move 0.25% or more in a single week during volatile periods.
