I wrote earlier this year about the temporary increased loan limits for conventional and FHA/VA loans expiring. The loan limits did indeed end up expiring. However, Congress voted a little while back to restore those increased loan limits to 125 percent of an areas median price (up to $729,750) for two years.
So, in our area this means you can purchase home with a conventional loan with a loan amount up to $729,750 before it will become a jumbo loan. A jumbo loan is harder to qualify for and also will have higher costs associated.
