I'll throw in my take on realtors in general. Town houses around here on Long Island run $250k+ anyway... so we opted to buy a house instead. At first, we went with a realtor to look around. We could get nothing even decent between $275k-$300k. We gave up with her after 2 weeks because she was showing us crap and new houses to market get bought within days because of MLS (the multiple listings service).
We found a for-sale-by-owner... instantly cutting off a potential 6% commission for the realtor that is usually passed on to the buyer by the seller's price. In my opinion, we get the house for the actual value of the house. True it's more of a hassle for legalities, but you're not paying an inflated price because of the realtor's commission. We're less than 2 months from closing on that house we found for-sale-by-owner.
As an example, during those 2 weeks, we were looking in papers for private sale homes. $319k house... couldn't sell it for 5 weeks, so he enlisted a real estate agency to help him. Guess what the new price was? $369k. Hell, we saw the house and it wasn't worth $300k. I swear.
Just some recent personal experience for you to chew on about realtors. When I emailed my realtor about not going with her anymore, she completely understood.
