I cleaned the area with a rag and about 10 days later it's coming back.

My father in law has always done things about 70 percent and the house is currently in that semi unfinished state (I spent 5k just to have it cleaned and functional before I moved in).

For legal purposes if you have a eviction the rooms need to be numbered, so keep that in mind.Shared type of roommate agreement for common areas, regarding cleaning, trash removal, laundry area, and overnight guests, and extra storage, also X marks the spot where you will park !!..

Tax wise you need to make a clean break.

Welcome, Joe, great to start with clean slate and little cash and time on your hands, I started in real estate after cashing out my stocks, savings and 401k paying being penalties but it was worth it.

That doesn't include Airbnb's fees, cleaning, management, etc.

She thought it was smells from a meth lab that was covered up/cleaned up but it just turned out to be a very bad mold issue.  

And they messed the kitchen cabinet painted all over into the appliances, so we had to clean up their mess.

If you get worked up on how clean your tenant is, or their general lack of concern that the lawn does not look  like a manicured golf course then it is time to hire a property manager.

It is currently vacant while I clean/repair for new tenants but I have added value over the years and think it is worth a lot more than I purchased it for.
