Like you mentioned , the prices are going down because a lot of people thought you could just buy a property and slap it on airbnb , expecting it to rent well without doing improvements , not realizing that the market would be overstaturated with " C and D " quality properties ( A+ are the properties i'm speaking of)I'm seeing that you can buy those type properties( A+ potential) that have simply been under utilized and 1.

That's why, its best to shop for quality lenders. 

If my husband and I were to start over again we would buy higher quality assets and not be focused on immediate cash flow and unit count like we were when we started this after exiting a fairly decent sized small business.

I haven't reviewed the Standard Lease Agreement yet, but all I need is the right to sublet, and possibly some negotiated capital responsibilities (owner pays for repairs over a certain amount or split responsibilities on certain expenses).

Homes are double story standard homes with around 21-24 Squares.

I am above 50% on standard Visa/MC, below 50% on Amex, and about 0% with anything that is like a local credit unions. 

Buy good quality things once rather than poor quality and pay multiple times to replace it.

You should also be aware to make sure what was provided does or does not meet industry standards.

Also make sure you have quality insurance with an umbrella policy.

You can also sell them on sites like paperstac, debexpert or others as well as brokers like Mission Capital, Rams or Phoenix.Depending on quality of paper and interest rate will determine sales price - also I would say self servicing can have a negative impact on the sales price as the major players in the space are not fond of self servicing.
