I foresee crushing failure in your future.

I think your recourse is a timely termination of the contract based on the buyer's failure to produce the deposit.

As mentioned above you could just act as lender and record a mortgage/deed of trust with promissory note and personal guarantee from all parties in the deal would be the cleanest way to structure the deal.Another option which could potentially yield higher returns on your money is to become an equity partner in the deal, this could put your money in a riskier position and in the case of a default or failure to perform of other partners. 

I haven’t had the experience (I’ve had 1 backup I covered out of pocket, one failure I also covered and two toilet supply line floods (make sure you’re stainless supply lines are braided and don’t look like snake scales or knights armor.)BUT, I have found more and more insurance companies trying to charge more and more for each thing they are covering.

This can result in column failure and subsequent structuralmovement of the home.

In my MO market they list the owners on the assessor website and it can be accessed for free - all I had to do was give them a reason for wanting the information (I told them I was an investor) and they set up the account for me.I would also ask them about their worst failures in real estate.

There is the Failure to Pay Rent form that must be filled out and a fee paid at the courthouse, then the court gives notice to the tenant.

I agree with the other comments above, having two middle men (home warranty + PM) is setting yourself up for delays and failure.

The biggest failures of partnerships are NOT MEETING EXPECTATIONS!

Failure to enforce your rules evenly could actually be seen as discriminatory.
