The vast majority of homeowners enter into lease and real estate transactions with the mistaken belief that the real estate agent is acting on their behalf. In reality, sellers usually pay the real estate agent a commission based upon a percentage of the sale or lease price of the property. The agent is legally obligated to protect the seller's interest and to seek the highest price for the property and to take whatever actions are necessary to close the deal.
Having an attorney review lease documents before you sign them can alert you to some of the many obligations you are assuming by taking possession of the property.
In purchase transactions an attorney can protect your interests by working with lenders to secure financing, reviewing the title documents, and attending closings to make sure the transaction is completed properly.
