We ran into the same issue when we made our Costa Rica investments and didn't really find a good solution for a local mortgage there. 

I would just excavate a few 2'x2'x2' (or larger if possible) spot footings, w rebar and Simpson hardware,under the house (you will want to take up the floor to make this easier to do).

I can only think of 2 times inn the last decade my client has had to go though an eviction and both times it started cause the owner and tenant had personal issues. 

Currently have a duplex I’ve been in 3 yearsMortgage 3.65% pmt $850Tenant pays $875Heloc $30k——monthly $291The issue I am running into isRates are so high right now and it’s a lot harder to find another that will cover full mortgage.Does it make sense to leave somewhere that it is full covered to go to one that is not?

But if you are saying that is always breaking or giving you issues, I know that can be a make or break.

The PMS around here are pretty terrible, I've worked with a lot of the larger ones in Cleveland and I think they just take on more properties than they can effectively handle and don't hire enough additional employees to make it work. 

Class midwest issues. 

You've got ADA, FHA, and the Oregon Department of Agriculture issues. 

Find a lawyer and issue a lease violation for other issues such as excessive noise and furniture removal.

The Fannie and Freddie programs handle this issue slightly differently.
