I even have my renters sign a liability waiver upon arrival, which I never had one person refuse to sign one yet.  

You have to sign an agreement that you will come up with the cash if the property appraises up to 10k below the purchase price. 

The seller will also have to sign documents that are required and it will hold them liable for debts since they are on title.Best way to set that up is run the numbers and create a partnership based on the equity of the land and your cash injection and sweat equity.

And then if that does not work it goes on loop net or coast star..

", just sign the deed over to them.

I prefer Rentredi for rent collection, lease signing, maintenance requests, etc.

It's difficult to see how a tenant will be after screened and signing a lease.

I even have a creative deal signed if I don't flip the contract.The purchase would be 300 + closing costs. assignment would be 15.

They can choose to leave and you can both sign an agreement to terminate the tenancy, or, you are going to file for eviction and it will probably wreck their credit. 

Then they won't need an upfront payment for work they haven't provided yet.Also, get a signed contract, copy of the drivers license, contractor's license and be added to their liability insurance.
