Many prospective homebuyers are still sitting on the fence watching trends regarding home prices and mortgages. They’re waiting for the most strategic time to make their purchase.

These consumers will be particularly interested in a study recently concluded by the Mortgage Bankers Association (MBA). It projects key factors that will shape mortgage availabilities in 2013.

MBA expects $1.3 trillion in mortgage originations during the coming year, largely driven by a spillover of refinances into the first half of the year. The association upwardly revised its estimate of originations for 2012 to $1.7 trillion.
