When buying or selling residential or commercial property, a purchase agreement is a must today. It is crucial to ensure there are no post-sale problems or disappointments, because the terms are made specific to the satisfaction of both the buyer and the seller. Trying to go it alone may lead to a far larger expense down the road without having the proper paperwork in place in the form of potential litigation. Buyers and sellers would be wise to use an attorney to draw up purchase agreements, because they need someone who is proficient with current law to keep both the buyer and seller happy in the long run. Buyers and sellers can also save in potential fees associated with using a title company.
