Journal About Home Loans, Mortgage Rates and Buying a Home

Looking for a mortgage? You'll face hundreds of rate quotes, each with different fees and requirements that can make your head spin. The interest you pay on a conventional home loan—that's any mortgage not insured by government programs—depends on everything from your credit history to what day you apply. Master how lenders calculate these numbers, and you could pocket serious money over your repayment period.

Fannie Mae and Freddie Mac set the rules for conventional mortgages, creating standards that differ sharply from FHA, VA, or USDA programs. Nearly three out of every four homebuyers and refinancers choose conventional products. Your quoted rate might differ by a full percentage point from your neighbor's, even if you're buying identical houses on the same street.

What Are Conventional Home Loan Rates?

Think of conventional loan rates as the price tag for borrowing money when no federal agency backs your mortgage. Fannie Mae and Freddie Mac establish the qualifying criteria, but they don't guarantee lender repayment if you default. That's the key difference from government-insured options.

You'll encounter two basic structures. Fixed-rate mortgages charge identical interest through your entire repayment period—lock in 6.5% today, and that's what you'll pay whether it's year one or year twenty-eight. Adjustable-rate mortgages (ARMs) tempt you with lower starting rates that change after an initial period expires.
