I'm 5'10'' ish and 185, so slightly stockier $& shorter than you but not to a point where we'd fit significantly different clothes. I agree it's slightly roomy, especially in the shoulders and biceps. That's precisely why it works for me though because if it was smaller I wouldn't move around comfortably. I can snap it up without issue despite that I don't really do it.
Best of luck in buying a house! Houses are expensive to get and care for but I consider mine to be very much worth it.
