Posting the ad is only half the battle. The advice given here is all good . . . Craigslist and Military by Owner are both great options. Although honestly, you should be able to get a pile of interest via Craigslist alone, and best of all it's free.
Here are my Five Secrets for Massive Rental Success on Craigslist:
(1) Set your rules in the listing. For instance, no pets and no smokers. Allow the listing to filter out folks who don't meet your criteria.
(2) Decide on one or two times you will be showing the house and invite folks to come at those times. Don't set 12 different appointments, invite 12 people to view the home at one or two predecided times.
(3) Don't accept the first person to apply. Plan to run credit, check rental history, verify employment and check court records for evictions.
(4) Let people know you will be running credit in the posting. You'll scare away undesirable applicant or they will "fess up" to the blemishes on their credit and you can decide whether you are willing to work with them.
(5) Understand that you will have to filter through quantity to get quality, but you can get great tenants on Craigslist.
(6 - Bonus) Be sure to include as much information as possible and include the max number of photos Craigslist will allow(8).
(7 - Bonus) Set up a separate gmail account just for your rental. This way you don't clog your other email address with rental inquiries and you have all the folks who've inquired in one place so you can easily communicate with them.
Hope this helps. You're success in your landlord experience will be largely dictated by the amount of time you spend here on the front end getting good tenants into the home. Don't be lazy getting good tenants in and you'll very likely have smooth sailing for the entire lease.
