Definitely an effective marketing strategy, and one I use all the time.
I even take it one step further and make sure my renters know why I think renting is the way to go. And not just for another year- there are advantages to being a permanent renter. People these days are not just looking for equity, they are looking for long term value.
I used to own a home, and I HATED it. The never ending chores of mowing the lawn, cleaning the gutters, raking the leaves, shoveling snow, and on and on! I want to go camping, shop, or read a book on the weekend.
In the four years I owned my own home, I had to paint the exterior, clear blackberries from the back yard (again and again!), get a new roof, new furnace, new appliances, and new wiring. Plus the city decided homeowners had to pay to replace sidewalks in front of their homes. Then the county decided homeowners would have to pay additional taxes beyond federal, state, and property taxes...
While renting may not be best choice for everyone, renting an apartment can be a huge value. Because we renters spend less on housing, we can afford better cars, bigger contributions to retirement funds, longer vacations, etc.
I am absolutely enthusiastic about being a renter instead of a homeowner. I love my apartment and my community. This attitude has an important impact in my sales pitch and my community's occupancy.
There is a funny end to my home ownership experience. The current owner made a short horror film about the blackberries in the back yard and put it up on youtube.
