in the current market your request is very reasonable. I would have your Realtor bring over a CAR form, they will know what that is and still submit your offer at the price you feel the home is worth regardless of commission. A lot of sellers sing a new tune when money is in front of them.
Hey Mathew. Wow big move! Difficult question to answer as well. I wish you could be a little more specific with your question as I do not know how much you want to spend and I do not know how far you are willing to travel to and from work. There are some wonderful Boston suburbs as you probably know. For instance, Milton, MA was recently ranked the 7th best place to live in the country based on many different variables. It is very convenient to Boston and, for the most part, has very good schools. A bit pricey? Yes but not as expensive as some.
