Offer accepted after withdrawl.

I placed a offer on a brownstone that was 12% under the asking price, and put the offer in writing. Seller’s broker comes back two days later saying that they counter with 6% off asking price. The counter wasnt in writing and was just verbal, nonetheless, I countered in writing, slightly lower than the seller’s counter offer.

After waiting almost 2 weeks I started to thinking and felt that I should wait out the market a bit. Also I started to feel like I was negotiating with myself. At no time did the seller’s broker put something in writing and fax it over. Also weird that they countered in under 48hrs, but wanted to sit on my final offer for more than two weeks.

Two days ago I tell seller’s broker to withdraw my offer. Now I get a call today saying that they accept my offer. I kind of want the house still but now at my original price that I first offered. Should I just wait another month, or two weeks like they did to make a decision.
