If they feel cramped they are going to be more likely to be annoyed with any other minor issues that may arise during their trip, which could affect the review they leave you.

The only two options at that point are get used to the smell or demo the affected components.

You might need to explain to this tenant that you will be pursuing a judgment if not paid and that it will lower their credit score and possibly affect what they pay for everything in the future from cars to insurance etc.No legal advice.

You may not know how to handle: tenant relations, maintenance requests, contractors, turnover, lease admin, property managers, "professional" tenants, neighbors, capital expenditures, municipal codes, federal laws, evictions, lawyers, budgets, taxes, etc. and how each one can affect the profits (or eliminate them.)

You can even use the same color and it still has quite a dramatic affect on the overall appearance.

We never planned on flipping, but it's difficult to ignore the opportunity, especially since it would be just about all tax free cash.Anyway, the other option is a equity loan to buy some investment property, which I may try, but we are purchasing some commercial property for our business and I think this large comm property loan will drastically affect our debt/income ratio and our ability to take an equity loan on our house.

@Beau Blinder That is the main source of my aggravation, knowing that something he does on my property could potentially have an adverse affect on me/property. 

We found a property that had been listed for sale and then pulled off the MLS repeatedly for years, with gradually lowering prices. 

OTOH, if they do have significant assets, this may come into play and make cause taxes to be generated for the heirs when they do die.The point is there are significant tax disadvantages to what they have done and they affect you (for sure) and them (possibly.)With that behind us, what's going on in the area?  

Repeat these steps over and over again from the Cash in, and refi out.
