Some of the best deals need cash or at least financing that is not contingent on an appraisal. 

This doesn't concern me much as the purchase can be contingent upon inspection which can be done during the escrow process.  

True, some turn key companies put big mark ups on their properties and sell them above market value, however, turn key companies that allow financed purchases and allow for an appraisal contingency can't do that.

I offered $50k cash for all the properties, contingent upon bank statements, lease agreements, maintenance history.

We're going to make out offer this week, and any contract will be contingent upon inspection findings.

Hopefully you can see use your financing contingency to cancel the deal if you can't raise any other funds.Good luck!

Unless you know how to handle the situation yourself then get a contract on the property contingent on your partners approval.

Your offer is more likely to be accepted when offering cash, quick close and no hassles as a loan can many times take 30 days or more and will be contingent on the property being in a certain condition.

And get an inspection, and make sure you have any and all contingencies included to cover yourself.I'm not a lawyer and these are just general ideas, not advice.

Not a Lawyer, but i think you just did it, just put in the sales agreement that the spot already has a renter and that they are to agree, and sign the agreement, that if they buy it that they will honor the current renters lease as a contingency for buying it, and provide them with the rental agreement.
