Hi Drew - looks like everyone has covered the issues from the real estate side - from the lending side, however, there will be a some things to keep in mind. The Good Faith Estimate your lender gives you will tell you what the estimated closing costs are based on the specific date you plan on closing. If you close sooner than expected, you'll have additional pro-rated taxes, insurance, and interest due as part of your closing costs. That means you could potentially need more funds to close. If you have an agreement for the seller to pay a specific amount towards closing and your costs are now more than he's agreed to pay - you'll need to come up with the difference yourself. I know in many instances where I'm selling homes, buyers have put everything they have into getting into the home and don't have any extra to come up with at the last minute. Closing 10 days early shouldn't make a huge difference - but if you don't have any extra cash, even a small amount could make a big difference.
If you think there's a chance you might want to close early - I'd have your lender run your estimated closing costs on an early closing date and aim a little high - no surprised that way. Best of luck!
