Its also better to get a written and signed statement along with their drivers license info and insurance information if the person admits fault at the scene and then you do not need to file a police report (which your insurance company WILL get) and you can file a claim against their insurance, this will minimize your risk of getting your policy jacked up next time you renew.

Ask your friendly title company to create a HUD-1 for youWith the offer attach pictures of all the ugly things about the property; the landscaping, broken windows, bad walk ways, bad fencing, green water in the pool, any nasty pictures of the interior, the estimate amount of renovations neededWrite a cover letter stating what you will do if they accept your offer; secure the property, insure the house, pay all cash, take care immediately of the roof problem, protect and secure the house form squatters, have the electric turned on, notify the water department, notify the local police to keep an eye out for vandals...etc.Since no one at the bank can make a decision as fast as you want, put a drop dead date in your offer.
