While you don't need an accountant for this as you can do your own research, and accountant can cut the research time in half, remove any noise, and tell you how that strategy can apply to your personal situation 

Noise ?

It is difficult to maintain, it scratches, it warps, it stains, it needs to be cleaned with cleaners made for wood floors, pets tear it up, it transfers noise, it shows wear patterns, etc. 

I think if you were sharing walls or in same house, then certain quiet hours in lease or noise restrictions can help prevent some issues. 

The internet is just full of noise and you can normally tell who is behind the product when someone talks about it. 

My tenant's dog shouldn't make too much noise.

(A) You run the deal, do the analysis, run it down, ignore the noise and follow the math. 

Generally, these tenants ARE harder on the property, harder on the neighbors (noise, excess cars, late nights) and have more drama than people that work for a living, or are otherwise independently wealthy.

If the noise is during quiet hours I will issue a lease violation.

I hope it's not my rental, those kind of noise complaints could hurt an investment.
