I second the lock on your bedroom door a must have regardless of a male or female renter.

I would also speak to his wife , Just a "hi" glad to meet you , maybe once your relocated here we could all go out to dinner once , as a welcome to the city. Besides you need to have a contact number for her in case something happens to him.

Do you have a written contract with this fellow? both sign and have a notary stamp it. The reason I ask is I once got into a mess once over not have such an agreement, according to state law (Florida) I had to go thru an entire eviction process , yes during which time the person did not legally have to pay me a dime in rent nor could I just change the locks. 3 months it took... I'm sure your situation will go smoothly, but one needs to cover all bases.

Just some thoughts
