home prices

I'm sorry this is unrelated to pregnancy, but I'm wondering how much your house was listed for and what your offer that was accepted was. We are working on purchasing our first home and our realtor is pushing us to pay the list price, but I want to know what an acceptable offer would be, and how low is too low to offer. Thanks :)
It's in one of the best school districts in the state, and homes in our price range here sell like wildfire. The list price is $160k, but we can afford $155k. Is that too low? We don't want to risk losing this home, but that is what we can afford.
