At a very base level, make sure the property is up to health and safety codes for your location. 

Unless the owner is mentally incompetent, or more than desperate, it most likely won’t happen.  

Over the past few years, my wife and I have worked hard to improve our financial health—we’ve raised our credit scores above 800, paid off all debt except for our mortgage and student loans, and saved a fair amount.

ROI factors in rental income, operating expenses, real estate market health, and property appreciation to assess the potential return.

If we determine that your dwelling should not be occupied because of damage or risk to property, health, or safety, we may, at our option, terminate this lease. 

Some states require an established relationship with the health professional, not just one evaluation, but many others, it’s just a letter from a professional if disability and/or reason for animal is not readily apparent.

Now mentally you need to get ready. 

I priced it only about 14% higher than the long term rental which matches traveling health professionals' budget on Furnished Finder.So I'm leaning toward longer term rental because even if I secure midterm tenant, that 14% more isn't really worth the potential vacancy. 

This helps you, as the buyer, understand the health of the asset.Where in the post does it say anything about what a seller makes?

The "immigrant mentality" beats the heck out of the "victim mentality"!
