I'm tempted to ask the county health dept (septic permits and inspections) about their position on outhouses, but I need to stay off their black list.

Whether that be child expenses such as 529 plans, contributions to a SEP IRA for retirement, or health insurance (HSA/HDP).

It turns out the heirs had agreed to pay the debt and signed a voluntary lien in their names with the dept. of health care services several years prior.  

Find out if there is some sort of health code you are violating.

In the short term, less than 6 months into a contract, they may not count anything, understand too the lender realizes that the due on sale is also an issue and it will be the responsibility of their borrower who sold with such methods and it can effect their risks if a borrower is caught trying to make that payment as well as the new payment., Most loans are not assumable after any period, that lender/note servicingi/holder may simply make a new loan and conventional  secondary market loans are not assumable, FHA/VA might be.

The health department or child protective services could get involved unrelated to the lease.

Tenant will be given 3 days to correct the problem or to remove the pet from the premises.14) Owner also has the right to enter the premises if there is reason to believe the Pet poses a threat to the health and safety of others or if a violation of the Lease Agreement or Addendum is suspected.

Even if the tenant objects to the invasion of privacy.Where if the inspection fails (due to not just legitimate health and safety issue but frivolous things like flaking exterior paint) you have to pay for a re-inspection each time until the property passes?

If his health declines before we're able to attempt something like this, that's fine - I'll still do it.

However, just as ambitious as I am for physical therapy and being a strong ambassador of health, I am equally ambitious and motivated to pursue real estate investing; specifically buy and holds for the moment.
