Hi Virginia -- I'm a bit confused. Did you see this home with your agent last weekend or did you just see the home directly through the owner? It is listed through a brokerage firm. May I suggest that you work with a real estate professional when you put in your offer -- wherever you choose to ultimately put out an offer. There are many pitfalls, particularly in this challenging market, and since the assistance of an agent to represent you won't cost you anything, there's really no down side for you--and it could well save you a lot.
If you would like me to refer you to a competent, ethical agent in the area, I'd be happy to. After you see properties in Ballentrae, you can ask her for a comparative market analysis on this property and begin your strategy for making an offer.
Best of luck. This home looks truly exceptional.
