However, you would have to rework your current contract to be subject to SS approval  (which the buyer may or may not be into),or sell to another party, and if you are getting financing for the new house, that will likely fall apart as well. 

If there is no Operating or partnership agreement tell both parties to never invest in this way again.

Quote from @Gino Barbaro: @Michael WhitmanDM me and I will send you our du diligence docGino Hi Gino,I'm in a similar boat to the investor who posted here. 

Is it worth having tenants use a 3rd party service/app for collecting rent, doing maintenance requests, etc?

You want to make both parties happy.Most wholesalers fail because they are chasing the spread (their money) and not focused on helping the seller and providing a win-win for the buyer.

I completely understand not wanting to "miss the boat" but if you know you're going to have negative cash flow you HAVE to know you can afford it. 

You can be sure your guests are not throwing a wild party in the back yard pissing off the neighbors.  

In this case, we saved the transaction by understanding what mattered most to each party and finding a way forward.What’s the most unique concession a seller has ever asked for in a deal?

I have learned from property management that boundaries/expectations are a must for both parties so that we can come to the common goal and avoid the burnout.

.: You’re late to the party, but its still possible, you will just be getting the deals all of the establish investors have passed over.
