Are you working with a Realtor from Haverhill? Your best bet is to find a qualified buyer's agent from the area and seek their expert advice. I see the property is under agreement on MLS. Are you the buyer it is under agreement with? It looks very nice inside. I suggest you lean on your buyers agent and ask them to perform a competitive market analysis on the property (CMA). Ideally, this should have been done before the offer was placed.
