After doing the program for couple of deals, I find out it is almost impossible to make profit on doing Flip with their system, since they are providing these stuff:1.Sourcing clients with deals on Zillow, that is anybody can do that, you can't buy a property with very low prices2.Asking un-credited investors to borrow Hard Money Loan, I don't really think anyone don't have much experience should borrow Hard Money Loan, with balloon loan mechanism, it is basically teaching new-bees to suicide.!

How much term is left, strength of the tenant, rent escalators, rent/sq ft, etc.You also want to make sure you have a good understanding of the roof, parking lot, and mechanicals because in a traditional NNN lease, the landlord is reponsible for these items..and they can get expensive.

Owning a car wash means you need to know plumbing, electrical, mechanical, and when to call the experts.

Modern floor plans, modern mechanical systems, well insulated, generally separately metered etc.

If my emphasis was on CASH, I would have just accepted the cash sale.

Once you have you team, all you need to make sure is that the property is in a good location, cashflows positive, has equity at purchase looking at comps, and making sure the mechanicals are good. 

Cap rates, location, and understanding the cost per door alongside your mechanicals and capex is going to be key when buying multi-family. 

They could in theory try to squeeze this into government guaranteed loan products, but it would be nearly impossible to enforce through that kind of mechanism.

@Roger D Jones what about a mechanic's lien?  

Lot's of people like to bang the gong of cash-flow, but reality is cash-flow is a mechanism of sustainability of operations, not some big profit center. yes, some like to twist it to be, via various function of neglect.
