Hi Janet
This was posted some time ago, so you may have already had your question answered. The market is going to determine the amount you are going to be able to rent your home for. Watch the local Trading Post to see what people are listing properties for rent. It's not as simple as a college town where homes are rented by the number of bedrooms, but rather on the condition and location of the home for desireability. You can test the market by placing your own ad and getting feedback. If too many people walk away, you are asking too much for monthly rent. As a previous landlord, I can tell you that once you get a good tenant, there is definite advantage to not charging the highest dollar amount or raising the rent but rather working with that valuable tenant!
Hope you were able to successfully rent your home.
