So far, we've had no trouble with our property just using Airbnb's insurance guarantees. 

I understand your comment however I know a turnkey provider that sold a house to a new investor for 38% higher then the value because they had no experience in real estate.

On my most recent deal, I offered on a property when I had no money at all, I showed the seller proof of funds by showing her my Vanguard 401k.

It was easy to setup, and my tenants had no problem getting setup via the invite email that they receive once they are added to a property/lease.

I had no idea how that was going to delight my wife and get her excited about risk in other areas!

Up until a year ago, I had no education in finances and real estate and in the last year have been furiously cleaning up my many years of financial mistakes.

I've had no complaints and they've been installed in some for almost a year.

I've had no luck on MLS, is it best to go after old listings that couldn't sell, write letters, talk to neighbors?

Between Solomon's and Jesus' time banks came into being and we can surmise from a parable Jesus told, that He had no problem with people borrowing as this would have been a necessity in order for the depositor to earn interest.  

Why didn't they call OFF the closing since they had no money/funds from the 'buyer'?
