Find a great local agent and have them set up a showing to make sure it's what you want. If it looks good, have them do some research to determine the value and write an offer. You'll need either proof of funds if you are paying cash, like a bank statement that shows enough or a pre-approval from a great local lender. It can take a day or two to get a pre-approval, so get this started right away. Even if you don't buy this house, you'll have what you need ready to purchase another one you like better.
