How much could you lose by waiting?Besides the loss of the tax credit, the biggest game-changer facing buyers is a potential jump in mortgage rates. If the Fed moves ahead with its plan to stop buying mortgage-backed securities at the end of March, the rate on a 30-year fixed mortgage is expected to increase nearly a percentage point from today's 5.18% to 6.1% by the end of 2010, according to the Mortgage Bankers Association. On a $300,000 fixed-rate mortgage, that's an extra $174 per month.But if home values are falling in your area, you don't have much to lose by waiting. If the house you want costs $375,000 today and you put down 20%, you'd pay $1,644 a month for a fixed-rate mortgage at 5.18%. Buy that same home for 5% less later on with rates at 6% and you'd only pay an extra $65 a month. If prices plunge 10% or more this year (as they expected to in 12% of the markets,according to Fiserv), you'll come out even or ahead.
