@Teren Cooley First, congrats on buying a property for a really good price! It sounds like you may not be real clear on the ARV (after repaired value), as you mentioned the assessor value and that is almost never accurate. I'm guessing you also had other reason to believe this was a good deal, similar sales etc...
I do a lot of wholesaling and fast flipping (wholetailing). The key is always price. I can make money on any deal in any condition, if I get it for the right price. If you did get it for the right price, it will practically sell itself to flippers and other investors. Bigger Pockets is a great resource and so is Facebook if you run inexpensive ads in the local area for the home and pitch it as a great under-market investment.
I also recommend calling a number of Realtors in the area and tell them that you have a great investment off-market. The more successful realtors almost always have people they know who buy and flip. They may want a commission but that is negotiable, and a small commission is well worth it to find a buyer quickly and make a profit.
