Each type of loan takes a different amount of time to process. The quickest is a conventional loan, but there are VA, USDA, and FHA that all have wonderful programs. USDA takes the longest but is a loan that requires no money down. FHA are the most common as it only requires 3.5% down. Call a local agent and have them help you. They are trained and are able to help you each step of the way and through all the loops that that come up. I would leave a 60 day window in your plans once you get a accepted offer. If it is USDA, your looking at closer to 90 days.
