We are looking to buy a house made in 1890. It has great bones but there are some rooms that really do not function well with the flow of a home. We want to knock down some walls to make it flow better, make bathrooms a little more spacious and updated, add a laundry/mudroom in one of the functionalless rooms...What should we anticipate? What should we look for during the inspection? How much would it cost if we have to rewire and do new plumbing in the whole house (2853 sq ft)? Is there a way to find that out before purchasing?
