How possible is it to move the law day back if the SS is already being negotiated?

The disadvantage of a shortsale is that your profit is in direct proportion to what you can negotiate with the bank and shortsales take a LOT OF TIME AND EFFORT to negotiate.

(I am an awesome negotiator) and I hold a 25% interest, the lender holds a 75% interest, but he/she would be registered on Title.

The demand that he step aside and let you directly negotiate could have been the problem.

Negotiating...I believe if more wholesaling "gurus" emphasized this tactic, there'd be less stress and heartache for wholesalers..Let's face it, some people who get into real estate via whatever strategy aren't great negotiators..they really have to work to learn it..

if you find a property that you think might belong to a motivated seller, how do you find out who owns it and how do you get in touch with them to see if it's for sale and start negotiating?

And he's already said he's negotiable on the downpayment.

The bank will not negotiate with you directly.

Option #1 will most likely meet that criteria, you can price for any major repairs/cap x improvements and negotiate those during the acquisition, this will help you hedge against major items breaking down once you acquired.   

Also commercial loan is very much negotiable ...
