I have friends who do that. Then the shitty city immediately starts citing them for shit. Got out of it. Let it rot
Good point, these empty homes often attract construction handyman who very well may have helped rental landlords along with unhouseable tenants ruin the home in the first place.
Also doesn't take long for an empty house to deteriorate beyond repair.
City inspectors and their building codes can be a problem, especially for under funded investors and their handyman who just think they know what they are doing.
Having said all that, In many ways it is easier to build a home than it is to restore one. On the other hand, the high cost of new homes is making restoration of older homes more reasonable than was once the case.
