The Federal Reserve gave home shoppers what they hoped for: a big rate cut and a signal of more cuts to come. Even so, aspiring homebuyers and homeowners eager to refinance should temper their expectations of a big drop in mortgage rates from here. What's up with mortgage rates? When mortgage rates rise, they can add hundreds of dollars a month in costs for borrowers. The average rate on a 30-year mortgage rose from below 3% in September 2021 to a 23-year high of 7.8% last October. That coincided with the Fed jacking up its benchmark interest rate to fight inflation. Rates have been mostly declining since July in anticipation of a Fed rate cut. The average rate on a 30-year mortgage is now 6.09%, according to mortgage buyer Freddie Mac. That's down from 7.22% in May, its peak so far this year. Even a modest drop in mortgage rates can translate into significant savings over the long run. For a home listed at last month's median U.S. sales price of $416,700, a buyer in Los Angeles who makes a 20% down payment at the current average mortgage rate would save about $312 a month compared to the cost of buying the same home in May. So, it's time to buy? While lower rates give home shoppers more purchasing power, a mortgage around 6% is still not low enough for many Americans struggling to afford a home. That's mostly because home prices have soared 49% over the past five years, roughly double the growth in wages. They remain near record highs, propped up by a shortage of homes in many markets.
