Since I have extended family living with me, the 4-br house on 1/2-acre is pretty much a necessity -- especially at the price; I couldn't rent more than a SMALL studio for what the mortgage payment is. In another decade, that will change significantly.
My garage (2-car, 21x22', at the end of a 180' driveway!) would be a palatial studio for me if I was alone.
Whatever the future holds, it'll be me and the bike until I can no longer ride. I seriously doubt there will be room for another RELATIONSHIP (forget spouse, ain't going for 3rds)!
