Here is a graph showing national vacancy for single family rentals and the vacancy rate for our company. (Sorry - this site won't let me insert the graph). What it shows is about 8% vacancy nationally. We get all these statistics from www.rentalhomepros.com. It's like an MLS service for rental houses that is owned by NARPM. All of our listings are there along with several thousand others and it enables us to look at vacancy rates, averages days on the market, average days vacant, and more. It also displays the data in graph form so we can see trends.
