Just make sure it’s on a masonry foundation with support piers in the crawlspace, with tiedown straps for protection in high wind. If it doesn’t have a good foundation with tiedowns they’ll roll or go airborne pretty easily in a downburst or heavy straight line wind. You want a pitched roof, too, otherwise you’ll be dealing with leaks eventually. You can find such properties all around the south in more rural areas for a pretty cheap price, but you don’t want one that’s been heavily neglected. If it looks too cheap compared to comparable properties for sale, there’s likely a very good reason.
I paid the tax lien on a property a few weeks ago. For $762 I got an acre of land and a trailer with a permanent structure built on. It’s been abandoned for a while. I can’t yet go inside so I’m not sure if it can be salvaged, but outside actually looks good with very minimal rot. Of course there is a 3 year right of redemption so I can’t rally do anything to the property until then but still a good investment.
