If you can tolerate students, that should be easy for 8 months of the year given where you live.
We've had students in the past (we actually rented out 2 bedrooms in our house in addition to my wife's mom in the basement). Fortunately, we had "mature" students: Foreign students and ones doing their B. Ed.
Ideally, we'd like someone 12 months of the year. Then again, we may think about moving to a smaller place (ideally with a garage this time).
Cheers, Derek
