I'm wondering if the return on equity is worth it or if I should sell and get into better investment deals.

That's who you contact to make a deal.

The deal is fully funded but I know of some similar opportunities.

I'm willing to give a percentage of all the contract deals I can get in 30 days.

OR it's a setup for failure and there too clueless to know which is arguably even worse because every little everything your going to be dealing with morons every step of the way, arrogant ignorant's.... 

There are many online marketplaces, including BP, where you can post your properties.Aside from selling by owner off the MLS, which offers the greatest flexibility to make a "deal" with an investor, generally it might be best to work with a seasoned investor friendly seller's agent that can guide you through the process and potentially find an investor.

We backed out of the deal instead of looking for other options.

If you are a solid investor focused agent, I’d be game to discuss land development + ground up construction of a well designed building you'll be fine in Fort Lauderdale or anywhere in South Florida. you will probably need more liquidity than existing but the deals are much better. 

Since this is an auction deal I have a hard deadline to close.

Or if it was offered in the competition because that might be a deal breaker for some people if it's not there.
