Understanding Mortgage Rate Types
The biggest decision you'll make when choosing a mortgage is whether to go with a fixed interest rate or an adjustable-rate mortgage (ARM).
Predictable Payments
Same payment amount every month
Budget Security
Protected from rate increases
Simple to Understand
No complex rate adjustment formulas
Lower Initial Rate
Start with lower payments than fixed-rate
Potential Savings
Benefit if rates stay low or decrease
Rate Caps Protection
Limits on how much rates can increase
Key Consideration
While ARMs offer lower initial rates, they introduce uncertainty. If you plan to stay in your home for a long time and want payment stability, a fixed-rate mortgage is usually the safer choice. ARMs work best for those who expect to move within 5-7 years or are comfortable with some risk.
Fixed-Rate Mortgage Deep Dive
The traditional choice that provides stability and predictability.
Your interest rate is locked in at closing and never changes for the entire loan term (typically 15 or 30 years). This means your monthly payment for principal and interest stays exactly the same.
Example: 30-Year Fixed at 6.5%
Month 1: $1,896.20
Month 360: $1,896.20
Total: Always the same amount
Planning to stay in home 7+ years
Prefer predictable monthly budget
Concerned about rising interest rates
First-time homebuyer seeking simplicity
Adjustable-Rate Mortgage (ARM) Explained
Lower initial payments with the potential for future rate changes.
ARMs are named by their initial fixed period and adjustment frequency. The most common is the 5/1 ARM (5 years fixed, then adjusts annually).
ARMs include caps that limit how much your rate can increase:
Example: 2/2/5 caps mean 2% initial, 2% annual, 5% lifetime maximum
ARM Risks
While ARMs can save money initially, they carry significant risks. If interest rates rise, your payments could increase substantially. Many homeowners faced "payment shock" during the 2008 housing crisis when their ARM payments doubled or tripled.

Current Market Context
Understanding today's mortgage rate environment.
As of November 2025, mortgage rates have moderated from recent peaks but remain elevated compared to historical averages. The Federal Reserve's policy decisions and inflation trends continue to influence rate movements.
Current Averages (November 2025)
30-Year Fixed: 6.5-7.0%
15-Year Fixed: 5.8-6.3%
5/1 ARM: 5.5-6.0%

Economic indicators suggest potential rate stabilization in the near future, though uncertainty remains. Fixed-rate mortgages provide certainty in this environment, while ARMs offer flexibility if rates trend downward.
