Home Improvement Costs

Often times a home will be sold “as is” or marketed as a “fixer-upper”. While these terms do provide an indication of the current state of the home, they can lead to a misunderstanding when it comes to overall expense. Minor repair fees can easily accumulate, resulting in a drastic disparity between the agreed upon asking price of a home and what it ultimately costs.
