Though Ron is correct that a standard FHA loan would be impossible based upon the conditions you describe, there is a very nice option available other than all cash. FHA offers a 203k program that is intended for just these circumstances. In a nutshell, the loan will provide the purchase money as well as additional funds to be used to make necessary repairs after close. The property would have to appraise at the purchase price as well as at the higher value after the financed improvements.
The easiest version of this loan is the expedited one which caps at $35,000 minus required set asides. If more is needed you could go for the full version but that will require quite a bit more work and expense on your part.
It often takes weeks, 4-6, between Trustee Sale and Listing on MLS.
Secondly, Vandalizing and dead lawns are tell-tale signs of am REO. The problem with them, is that FHA (for example) will not finance a house that has Health and Safety issues. Often, this regegates the house to CASH BUYERS. Recently, some new Fixer Loans are available for non-cash buyers. Talk to your Lender.
For the Damage, I would go through with a yellow pad and make my own list, or you could take a contractor and your Inspector with you.
Good luck and may God bless
