Search for rental housing on the MLS on my sites:
1- find a home by map
In lower left corner you’ll see “property types” – scroll down and find Residential Rental and click the box to select it
You can input bedrooms, bathrooms etc. in the fields to the right of it. I input 3 bed or more and 2 bath or more and got just 25 results
2 – simple city or town search on my blog
Scroll down and view the left sidebar – you’ll see Real Estate Search in the left sidebar (just over the list of zip codes) – input the area/size you want and where it says “all property types”, do a pull down and you’ll find “rentals” as one of your choices.
