Lenders will probably see you as a reliable borrower who is likely to make payments reliably, so in this case you may actually qualify for the lowest advertised home interest rates. As of October 2015, the current mortgage rate was around 3.8%, for a 30-year fixed-rate mortgage, according to Freddie Mac. Of course, these 30-year mortgage rates fluctuate. Average mortgage rates don’t just depend on borrowers’ credentials. They also go up or down with the prevailing interest rate in the economy.
