There are pros and cons to each situation. if you sell the home; then you have the finality fo it being out of your life. The burden of repairs, up keep, taxes are all lifted off of you. In addition, depending on your situation, you have the ability to walk away with some money in your pocket.
If you rent you are hoping to land a tenant that will pay on time, keep the place presentable, maintain the up keep of the house for you. Now, it is not as gloomy as people say. But, there is a lot fo work involved in renting. You are basically on call for any repairs that need to be done to the house. Make sure they pay the rent on time, and that they are keeping the place in reasonable good condition. I have had good luck with tenants like thsi in the past. However; I also have ahd tenants that were the opposite as well. The cost fo that at time s made me think if it was worth it. You have the issue if somethign happens and they do not pay the rent, while you are evicting them, can you cover that mortgage paymetn as well.
The choice is completely up to you. It depends if you are comfortable with the upkeep of being a landlord or not.
