"There are at least 10 solutions to every problem/challenge" If we think long and hard enough, the answer will come.

And absentee landlords are frequently late or non paying.So the obvious solution is to pay on time.

Why isn't solution listing it on a MLS-like service (in TX seem like a few who will do it at $400 flat fee), and scheduling an open house for 2 weeks from the listing date.

The good news is you can take advantage of it by filling the void and offering extremely reliable service by working quickly and always doing what you promise.Loyalty counts – both ways, and is easily earned when an active borrower knows they can rely on you to get the job done 100% of the time.

SAAS solution where they derive fees from promoters for listing deals on the site.

My value to the deal would have been the repositioning of the park from a mediocre asset to one that cash flows reliably and consistently, paperwork, evictions, and all other such clerical work.

So notice the solution was a halfwall to fill in the gap, which creates a tub length shelf (angled to prevent standing water) for shampoo etc.  

Wholesaling using a double escrow is just one technique.You can use an option or an assignment.Is it unethical to deliver a solution to a seller who has a problem & you perform as promised?

That potential option is now off the table, so I would like to sell it and reinvest in a property with positive cash flow.So, I'm looking for a win-win solution here.

None that I know of, though many gurus claim to have the solution.
