I know every property has different needs... but what do you recommend I do regularly as far as maintaining the property.

If not you might try a regular listing...  

If you have a lease you may be able to use that revenue as regular income when calculating the loan amount.

If goverment is paying part the renter has to pay their part promptly and on regular basis.  3.  

For regular 120 V wiring, if there is an overload or short, the Romex might temporarily have to handle several thousand watts, without getting hot enough to start a fire, before the circuit breaker in the main panel pops. 

Streamline (regular) $35k and under reno funding. 

Unless they are behind on the mortgage, they should continue making their regular payments. 

,We do regular pretty tile in bathrooms and kitchen, and do wood-looking throughout the rest of the houses.    

However, if my good clients or realtors send me a gift at Christmas or in a Thank You note, as a regular part of business communication, and without expectation, I really don't see a problem.  

When you have lots of rentals, the worst happens with regularity and so does the best.
