Renting a room in vacation home, how'd you get spouse on board?

[Kevin C.]

So we have a vacation / second home in another state that we generally use about 1 week a month.   I suggested to my wife that maybe it would be a good idea to rent a room out to accomplish two things, bring in a little cash and have someone at the house so it was not vacant when we were not there.   The house is in a historical district, walking distance to a University, a historic Main Street area and not far from a Community College, so it's in a somewhat touristy location with a lot of potential students as well.

We talked about it a little and she was on board with the idea so I posted an ad on craigslist and got an inquiry a few hours later.  The potential tenant is a college student, just starting their second year that works at an upscale restaurant walking distance from the house.   Student currently rooms with 2 other students in an apt whose lease is up in Sept.  The other 2 roommates are moving elsewhere, so student needs to find a new place.   Our place looks to be ideal.  Sounds good so far, right?

I advise wife that we have a potential tenant and suggest the steps to begin vetting the tenant.  A few hours later she tells me, No, she's not comfortable with a stranger being in the house when she's there - in other words, no deal, no renting a room.   

Wife said she'd be OK with renting out the place as a VRBO when we're not using it, but no renting rooms.  I'm good with going down the VRBO path, but really liked the idea of renting out just one room so the place would not be vacant when we were not using it and the rent would have been almost 2/3 of our carrying costs for that house.

Has anyone run into this and if so how did you deal with it?
