I would prefer a 100k rehab for a 200k profit on this much money plus have more room if things go wrong.

This would definitely make it worthwhile to sell, because I was all-in for Duplex C for $165K, can perhaps sell for $185K after closing costs, and that would put me at $20K profit (which will be taxed, short-term ordinary income bracket). 

He would split the profits. the area Is consIdered hIgh end and partIcularly hot neighborhood.

Was able to negotiate a master lease for the property and take over management prior to purchase in order to generate some of the funds needed for the down payment.

I use the peoplefinder as part of my probate lead generation system.

Its a good deal for us either way, but of course, want a higher profit margin.  

He had not been successful at selling yet because it was not profitable at that time.

The basic reason you would want to keep getting more properties is because the return in real estate is higher than the cost of borrowing, so you want to borrow as much money as you possibly can and make it all generate profit for you. 

And, everything else you said boils down to PRECISELY what I said--the mortgage company is generating a lot of fees IN ADDITION TO their advertised interest rate.

She won't even let us use electricity and I don't have a generator right now.
