@prayingwife2015 You’re paying 2k/month, that’s a bargain for what you describe (garden, 10 min from work).
Take the extra space, make a gym/room for the dogs/room for family and friends to visit.
Maybe in 1-2yrs your new girlfriend moves in and you’ll need the extra office space.
If you downsize to a 3.5 or a 2.5, how much less would you be paying?
