First House under contract

[Natasha Wilkinson]

So Wednesday I got my first house under contract. The goal is to wholesale it to an end buyer. Its a 2 bed, possible 3rd in the full basement. 1 bath. 984 sq ft. House is renovated, however it needs cleaned. It needs minor repairs. Anyway I've had it on postlets for the past 2 days and craigslist for the last 3 days. [b]No bites yet. Its under contract for 12K, I offered it at $21,500 with the goal of getting at least 4-5k out of it. The house is worth 38k. Maybe my price is to high? I expect to get talked down, which is why I priced it as such.
The people who I have on my small list of buyers list, haven't responded.
I do have the addresses of landlords and people who purchased houses at the foreclosure auctions in the recent past. Do you guys think it would be appropriate to print out the postlets page and snail mail to the cash buyers houses??

I know its only been 3 days, but the clock is ticking and I don't want to wait until the last minute.

Thanks Again Guys!
