I have seen many properties where investors squeeze as much profit as possible without doing any maintenance then when it's at a breaking point they sell it to a new investor because it just looks so great on paper.If you do end up putting an offer on such property I would make sure to do a very good due diligence and even talking to the current renters.

With the interest on the remaining balance, the seller actually profits way more than their initial goal price. 

A partner typically shares in the profits (or losses) on a deal.

Looks like you learned a lot and made a good profit!  

My idea is to split lot, and partner with a builder to build a home and sell it, splitting the profit.

Let's say I sell the property at the ARV that the cashout refi is based-on, and I don't profit from the sale.

I reassign the already reassigned contract and take a cut of the wholesalers profit for finding the buyer - assuming the agree (joint venture agreement, or something similar).

Feel free to throw some profit in there.

I'm very serious about investing and my house is currently under contract to be sold, so I want to invest the profit wisely. 

Our plan has been to work on this house, save as much money from our 9-5's as possible and learn as much as we can through books, forums and mentors before selling and using the profits to get into multi-family units.
