Mortgage rates are not arbitrary numbers — they reflect a combination of broad economic forces and the specific risk a lender takes on when they lend to you. Understanding what drives rates helps you approach the homebuying process with realistic expectations.
The Economy and the Fed
The Federal Reserve does not set mortgage rates directly, but its decisions on the federal funds rate influence the broader borrowing environment. When the Fed raises rates to cool inflation, mortgage rates typically follow. When economic conditions soften, rates often ease. Watching economic news is worthwhile, but trying to precisely time the market is rarely a reliable strategy.
Fixed vs. Adjustable-Rate Mortgages
Fixed-rate mortgages lock your interest rate for the full loan term — your principal and interest payment never changes. Adjustable-rate mortgages (ARMs) offer an initial fixed period, then adjust periodically based on a market index. ARMs can make sense for buyers who plan to sell or refinance before the adjustment kicks in, but they carry more uncertainty over the long haul.
Your Credit Score and Loan Profile
Lenders price individual loans based on risk. A stronger credit score, a lower loan-to-value ratio, and stable income typically earn you a better rate. Improving your credit before applying — even by a modest amount — can have a meaningful impact on the rate you are offered.
Down Payment and Loan Size
A larger down payment reduces the lender's exposure, which often translates to a lower rate and the elimination of PMI. The type of loan (conventional, FHA, VA, jumbo) also affects the rate you will see, since each carries different risk characteristics in the eyes of the market.
Rate Locks and Timing
Once you are under contract, ask your lender about locking your rate. A rate lock protects you from increases between contract and closing — typically 30 to 60 days, sometimes longer for a fee. If rates drop meaningfully after you lock, some lenders offer a float-down option.
The clearest picture of what rate you would qualify for today comes from an actual conversation with a lender. Get started with a pre-approval at First Look Home Loans — it is free, low-pressure, and gives you real numbers to work with.
