is this a real offer or just locking me in to a wholesaler

[Dan Doughty]

I'm selling a property.  I've posted it on Craigslist(it's low end property) for a while but it's not moving.  I've dropped the price and also called back on some yellow letters I was sent.  

i've got a yellow letter guy offering me a "contract" but this is my first time trying to sell a house myself.  When I read the contract it sounds more like he's locking me into a wholesale deal and not committing to purchase the house.  I didn't demand earnest money and perhaps that was a mistake.  But I haven't signed anything.  

When I talked to him on the phone he sounded fairly realistic about closing in a few weeks and understood the process.  He has a closing company that he prefers and they seem to specialize in fast closings.  I looked him up on LinkedIn and he has a degree in marketing and is new to investing to.  He started in january 2015 acquiring properties for a local investment company.  

I'm not anti-wholesale.  I just want to sell the property and not lock myself into exclusivity with someone for a month.

Thanks for the help,

Dan
