Good luck- and find a management company that you trust.
This take a load off your shoulders and the management company will keep you out of hot water. If you are any distance from the home - it will also give you peace of mind.
Much luck to you. If you do decide to go it alone - get lots of education on the laws in your state.
There are plenty of ads you can place on the internet. Craigslist.com like Perry mentioned is great. You can also do a search for rentals in your area and you will pull up other rental websites. A couple are rentclicks.com, choiceofhomes.com. YOu can also contact Property Management agencies which can assist you as well. Hope it all works out! Have a great day
