I have a tenant with a boat and a race car in a trailer , another tenant that brings home his Kenworth tractor ( no trailer ) to wash and wax it and do some repairs .

Do your homework now while you're young, burn the midnight oil and the candle at multiple ends to get the knowledge you will need to do everything you want to do.

Buring the candle on both ends...Goals for this year?

If you are getting title insurance also will need to use a closing agent etc.If you are trying to wholesale a home with owner financing that is another ball of wax, as most seller financing deeds of trust ARE NOT assignable due to legalities involved with Dodd Frank.

It could be something as simple as a rocking toilet/bad wax ring seal.

The last time I inspected the backyard was about a year to maybe 10 months ago , when they let a simple fix of a new wax ring on the toilet flow water for several months not telling me and ruined the tile floor.

IMO, just give the tenant some money, light a candle, and learn a lesson.

My good CPA retired a few years ago and his replacement couldn't hold a candle to his work.  

All can be fixed with the replacement of the toilet and wax ring...which shouldn't cost you more than a couple hundred bucks.The foundation issue is a completely different story.

If you're diligent and have a LOT of time, and a lot of cups (wax paper cups wear out) then it's certainly possible.
