The other thing is this, in New Jersey, you can make a pretty good living working rentals. While all real estate commissions are negotiable, typically they run between 1 month's rent and 10% of the lease for a rental. Compared to a sale the transaction is fast and easy, no attorney review, no home inspection, no mortgage commitment. I am closing at least two myself this month. I do rentals to supplement my regular home selling business and it pays off.
If you have your real estate license, or are considering getting your license, you may want to consider rentals as a vital part of your real estate business.
