$500 / 5br - 3400ft2 - Room for rent (Female only) (Fredericksburg)

I’m open to renting out a room in my 5 bedroom house located in an upscale neighborhood that’s close to 95 and plenty of shopping.
Ideal person would be a single female that’s a non-smoker, no pets, low key, quiet, neat, clean and organized.
monthly rent is $500 but open to a lower monthly rent in exchange for some light housekeeping and a home cooked meal here and there.
I’m a tall attractive single guy, 51, I work full time and travel often so I’m not home that much.
