Websites are a fantastic way to gain exposure.

When you keep repeating this you will end up with a lot of properties that cash flow less than your first one but the aggregate will much bigger (plus you will be diversified, have more exposure to appreciation and move depreciation tax benefits)

I agreed with what you said,  but disagree with the emphasis  because if there is potential exposure to a discrimination claim (absolutely agree) then whether or not it is of itself a protected status is of less importance.

Zillow get's the most exposure. 

If they are lending money to you to buy the building on 123 Main Street, they only want exposure to risks from 123 Main Street, and not from a bunch of other properties that you own elsewhere.

IMO,  STRs are a poor business model in the first place due to the high turnover and exposure to excessive vacancies.  

INSURANCE: You will find Insurance costs for a Brick or Rock Property might costs SLIGHTLY less due to reduced exterior maintenance and exposure for the Insurance Carrier.

That said, in order to limit potential exposure I would propose that a detailed video walk through could be made for the property. 

The loans are still in our names, so not sure how much exposure that gives us.

It depends on the property - What is the risk exposure of the property?
