Investment Real Estate is a Lucrative Source of Income

My aunt who is a nurse at one of the biggest hospitals in New York is now into investment real estate.  She really isn't a business woman but since she and her husband have saved quite a sum of money over the years and both of their kids have finished college, they thought of investing in real estate.  Ten years ago they bought their second home in Flushing and it is being rented by my uncle's colleague.  In 2008, they bought another house in lower Manhattan and now they are looking to buy their fourth.  All the properties are earning well and the couple is thinking of retiring.  With all of their properties earning well, they could afford a pretty comfortable lifestyle.
