There are charities and government services that will help people in bad circumstances. 

I feel like the government will be regulating more.

He may owe taxes also to government.

@Rob Tesnear You'll have to check with the local government entity in your area in charge of titling mobile homes.

Hello Granville,Wow, I feel your frustration and empathize with you with government agencies.

If you need more help, I'd contact the local government entity in charge of titling mobile homes in your area and explain the situation.

See NC REC case file D13-0168 for the grotesque details about what happens when a state governing body hands a convicted habitual felon a license to continue to steal from the public. 

All other things you mentioned are very important as well as the market/sub-market we are in, demographics, vacancy rates, city/county governance, etc. 

We can do good quality we can do maintenance grade as well, one of our major sectors is government facility maintenance.

If there are any moral issues at all it is on the part of tenants withholding rent money and the government regulations encouraging the behaviour.I have no moral issue regarding how I, as a landlord, treat a non paying tenant.
