Without seeing the exact property it is hard to make an exact judgment but again it does seem overpriced.
Hope that helps.
An experienced buyer broker/agent who knows the local area will have the information you need to get the house you want for the best terms - an offer is more than price. If the house is listed with a real estate agent, they will pay a buyer agent, so there is no reason for you to go it alone. The seller has representation, why wouldn't you want a real estate professional working in your best interest? You have nothing to lose and everything to gain. If you would like help let me know - good luck, Marilyn
