Your only option would be to sell the house.  

Just sell it?

I'm new to the wholesale / fix&flip / rehab strategies for buying & selling properties, and one of the main barriers to entry I run into with potential interested investors are the capital requirements to start their first project. 

or "be near Temple University" I am from NJ/NYC area and am looking to identify the next big/upcoming neighborhood in Philly?

Lots of them are trying to sell courses so be cautious too. 

We (wife, two kids, and I) are selling our property in Houston and moving to small town, coastal Maine.

I've seen it happen several times where the seller thinks he's selling a deal at a 6% cap but the buyer thinks he's buying the deal at a 7% cap.

As for an offer, start with your ARV and subtract out your renovation costs, financing costs, a reserve amount for contingencies, any profit margin if you plan on flipping it, closing costs for both the buy and sell sides, and soft costs for the permitting, etc.

When the market slows enough, people will start to sell off, which will drive down prices, which will reduce equity, will will drive people to sell off, which . . . you get the idea.I'm just a nobody with an opinion, and I've been wrong at least twice in my life. ;)

I'm aware of a couple off-market deals that I've dug up for other investors, and I know a local investor that owns over a hundred of units that he'd consider selling, all the way from bare land, to single families, to multi-units including several apartment buildings.
