You need to be careful, there are a lot of houses on the market but you need to select by 2 criteria; 1. the home you like can not be a bank owned or a short sale because they can take months to close and 2. it should be vacant because the homeowner should have moved on and not contingent on the homeowner finding home of choice. The 2 criteria could seriously reduce the available inventory. I can help, I have area and relocation experience.
If it's less time than that though and assuming the seller(s) agree, make sure that the lender, appraiser and all other parties involved in the transaction can get everything done in time. The biggest reason for settlements to be delayed is the lender not having the loan docs completed and over to the settlement company in time.
