I can think of a few alternatives that would take a couple of hours to write (including caveats and if/then scenarios). 

I searched for alternatives to CC but it mostly points to RentRedi, AppFolio, etc, other cloud based options that he doesn't need.

There is, however, a small minority of investors who make this work with alternative debt financing of course, and institutions do own about 2% of the SFR market.

His alternative was losing this sale, and going to court to establish clear title.We did not get a 1099S from the title company. 

Looking for alternatives.

Google to find alternate addresses for them.  

The other (and more complicated) alternative would be to sell the properties to a 3rd party entity that preferably has other OZ properties under its fund.

On paper it looks good, but in a real life scenario projections might be different:-the third R, refinance could be possible if good credit and debt to income ratio are satisfactory...since many aspiring investors are far from that, what are the alternatives?

Charge them - go with maybe granite or a cheaper alternative that consumes the deposit in-full and you have no out-of-pocket cost associated,To your success!

They do not want to advertise it because they depends on their dollars and have not figure out alternative way to revenues, but that is the reality.
