Would your purchase price cover all principal, arrears and legal fees or was it a short sale?

The note on the door is a great idea so will do that, since it's not a true "emergency" and it covers me if there is a complaint filed against me about it. 

They list all their contact info clearly, and project a pretty legitimate image.I'm a property manager and got a spam/promotional-type email from them, saying that they do tenant screening for FREE.

Am I correct in assuming that another requirement is to have a certain amount of cash reserves saved up to cover any unexpected expenses?

Since then he has mostly bought apartment complexes and has never lost any money and talks down about owning less than 32 units which usually allows you the chance of hiring an experienced Property Management Company to handle the daily operation that includes the screening and maintenance and you just manage the managers and get regular (once a week) financial statements and you still have positive cash flow.

You got to have all your social media covered.
