Thank you so much for your response and input.
Frankly I've lowered the price because I have a lot of competition here.
I don't mind bargaining and "giving a little break" but I've had a few that suggested prices that would basically cover the cost of the extra utility use. Those I thanked for their interest but passed on.
I decided to do long term rather than a night or two for a few different reasons.
One being I live in a small HOA community where the neighbors would probably object to a lot of "coming and going." Another is I travel out of the country at least once a month so can't have folks coming and going for a few nights because sometimes I'm places where I can't be reached. I like to be here when they arrive to orientate them to the house and the surrounding area.
I may write up a simple rental agreement for this tenant and and ask her to sign. In retrospect I should have asked for a security deposit.
As far as cleaning; I ask that they do their own sheets, laundry, bath and also vac their room. The same with kitchen use; I expect them to clean up and leave it as they found it.
I do supply all toiletries along with kitchen staples.
Last summer I had an awesome summer intern. Hopefully this year's will be also be a pleasant experience.
Food - if I cook; I invite them to enjoy it with me.
Basically I want them to feel at home, relax and do their own chores. 😉
