We will turn into a tiny house village. 

More effort should go into enforcing existing permitting laws and cracking down on unpermitted work rather than imposing costly regulations that push property owners into avoidance tactics.If the goal is to improve fire safety in Worcester’s aging multifamily housing stock, the best approach is to encourage full renovations that bring buildings up to modern safety standards—not to place additional financial burdens on responsible owners.

But about 1 year after we bought the property, they started cracking down on the homeless in downtown Jacksonville moving the crime to the neighborhoods just outside of Jacksonville.

To help avoid a lot of these issues I would think about buying a "Modular" or use a "Tiny Home" vendor who offer these in many states.

I say to look at these hard because these items can occur for a period of 12 months possibly without major issues of seeing large cracks or settling if a lot of water hasn't been present in large volumes.

You can often uncover major things with a little research before you view the property - Ages of appliances, HVAC system, foundation/cracks, plumbing leaks, small electrical things (bring an outlet tester), signs of previous leaks, termite damage etc.

The foundation has a crack where you can see they tried to put tar or flex seal over and there is heaving in the floor.

Those couple of little small stress cracks  in the wall you took a picture of as well as the hole in the door are easy fixes.
