Bryan, this is a risky method, you mess up and you're open to civil litigation by the seller, if you leased it, you have another bee in the hive.Sub-to is best used to take title, go in and do the work and sell it.

Remember that the cost of a survey is negligible to attorney costs and litigation that can occur over property and in the end you will have a piece of mind where your boundary lines are, where your property corners are and most importantly where the improvements sit on your lot relative to easements and other encumbrances.When it comes to FEMA flood elevation certificates, just get them complete (again, by a capable LOCAL surveyor).
