I am glad to report that I like to rent rooms and it has worked well for me. Although most places put the cap at renting to no more than 4 people. But mine is not a typical rooming house it is more like a guest house. Every room is fully furnished with matching furniture, including the living, dining, and kitchen. the home is equipped with everything right down to smart tv, forks and spoons, small appliances, iron and ironing board. Every room has a mini fridge, lockable door, smoke detector, peep hole. First aid kit, fire extinguisher. Fortunately in our area parking is not an issue and I cultivate good relations with all of my neighbors.
I think rooming/guest houses fill an important need. Tell me where is a guy just coming in from out of town going to find a reasonable priced furnished room with no lease to sign. With couple of exceptions I have not had a bad guest. Recently we got our first female guest. We do not allow smoking, minors, couples or over night guests. I live in the house. I would really like to replicate this success in another city I love in Texas. I charge $475 pm plus $75 each for all the utilities (power, gas, water, cable TV, internet). I would think this arrangement only works in large or college towns. Make no mistake this arrangement is quite a bit of work for the owner. I am retired I don't mind.
