Rent out basement without washer and dryer

[Joe Au]

My wife finally agreed on renting out the basement. It's 2 bed 1 bath, 1200 sq ft. It has a kitchen, large living room and separate entrance. The only problem is it doesn't have washer and dryer. There is no laundromat within 10 miles. And I don't think my wife would want to share our laundry room. What is my option? Add a the hook up in the basement? in the garage? And what is the price range? 

Thanks,

Joe
