There are ways you can structure the agreement such that only one party can exit, for example by selling his share to the other partner (or someone else for that matter), refi on the name of the other party and cash out his share of the equity.Have a look at the BP fileplace you'll find there partnership agreements.

It's not an issue for all practical matters (key word).

Also I don't know if it matters or not but I'm in Indianapolis, IN and this company is in Miami,FL

If I can buy the property at a discount, sell it to an investor and a full price and make a fee for the due diligence and ancillary services we provide, does the source matter that much in the end?

Any advice on how I should handle this urgent matter is much appreciated.

Then, there are always the hardcore escrow pricing that some companies put out there that will beat you out no matter HOW CHEAP you get.

There could be a number of reasons that the contract fell through, but what matters now is that you get it under contract, go through your due diligence, and make some cash :)

Please if you have any advices about this matter feel free to guide me.ThanksWill  

From what I understand, rental property values are more based on the cash flow than "comps", thus, does the ARV even matter?
