My kids are interested in purchasing a home built in 1942, in New Jersey. After inspection, they were told that the house has some structural damage, caused by termites. They really like this home but this new found problem may cause them to change their minds, if the owner is not willing to cover the cost. Is this an expensive problem to fix the floor joists, on a home this old? Being a novice, and no experience with this type of issue, a contractor and structural engineer, or telling them it may cost about $20,000 - $30,000 to repair. Please help, they are expecting a baby in a few months and need to make a decision on purchasing this house.
