I hate to sound like a party pooper, but are you sure you'll have capital gains? most people do not when they sell in such a short time frame, in fact, their are lucky if they can get out and break even. It may be helpful (depending on how unique your home is) to run a market snapshot and see what current sales are - you can do that from my home page (follow link below). In the middle of the screen you'll see a small rectangle (not at the top of the page) that will have a small form to fill out. It says Market Snapshot. It's an automated report, and takes 15 mins or so to reach your email inbox.
As for a CPA, call Robert Tilker in Vienna. He is my dad's CPA. If you can't find a listing for him, email me (firstname.lastname@example.org) and I will get the # from my dad. He's worked with my dad for years and years.
