I've sold while in your shoes before, and I've also held with large negative CF.

I had severed ties with them for many months, and they expect me to use them to sell my property?! 

You have $70k in equity tied up, earning a low return relative to its potential.

In essence, they hand-hold you through on how to do two things:  First, find and tie up a select vacant commercial property, then Second get a prospective tenant who would agree to move into that subject property at a future date. 

They can tie up the property with a lis, but if you're not planning on selling, doesn't really bother you.

Basically a concrete slab with pillars, hurricane tie downs and skirting with axle removed. 

Put yourself in the shoes of an investor: is the property in a good market?

Remember, you may be tied up in several houses with little cash, so it is important to think of all possible situations.Who is doing the accounting? 

However, keep in mind that tying your primary home to an investment carries inherent risks, especially if the flip doesn't go as planned.

I'd add something that ties in with the couch.
