Newlyweds Eric and Pamela have finally found the house that they have been looking for and are anxious to make an offer. The 3 bedroom house is on the market for $156,100 and will require that the couple complete some repairs such as installing a new roof and replacing the deck in the back of the house. They estimate these repairs at about $15,000. The house is currently assessed at $150,000, however the real estate agent is confident that if they make the repairs, the market value of the house would increase to $175,000.
