How Interest Rates Affect Your Buying Power

Interest rates feel abstract until you see what they do to your monthly payment. A one-point change in rate can move a typical payment by a couple of hundred dollars a month — and tens of thousands over the life of the loan.

Example only, not a rate quote: on a $300,000 loan over 30 years, principal and interest is about $1,799 at 6% and about $1,996 at 7%. That is $197 more per month — about $71,000 more over the full 30 years. Each one-point increase raises the payment roughly 10-12% in this range, before taxes and insurance. This directly reduces how much home fits a specific monthly budget.

In the same kind of example, $2,000 a month for principal and interest supports a loan of about $333,000 at 6%, about $301,000 at 7%, and about $273,000 at 8%. Every one-point rate increase cuts that by roughly 10%. This is why rate changes dominate housing market headlines.

No one can reliably predict rates or prices. You may hear "marry the house, date the rate," meaning you could refinance if rates drop. Treat that as a possibility, not a plan: rates may not fall, refinancing has closing costs, and a lender will look at your income, credit, and home value again at that time. You cannot renegotiate your purchase price after closing, so only buy when the total monthly payment fits your budget today.

• ✓In these examples, a one-point rate increase cuts the loan a given payment supports by roughly 10%
• ✓Example only: on a $300,000, 30-year loan, going from 6% to 7% adds about $197 a month and about $71,000 over the full term
• ✓Refinancing later depends on future rates, its costs, and how a lender evaluates you then — it is not something to count on
• ✓Only buy when the payment fits your current budget — not a projected future rate
