You can do this your self.
1. Do a back ground check
2. Take pictures of the house inside and out
3. Return two weeks later to do pictures again, with there " stuff ' in the house.
4. Have a rock solid contract, if you do not have one, you will need to get one, I do not recommended writing your own
5. Know all the in and outs of how to evict your tenant if needed
I personally believe hiring a property management firm is well worth it, let them handle all the headaches.
I DO NOT have rentals, I've been a professional handyman for 15 years, I see and heard it all...
