After having seen the house, here is a new list of the pros and cons of moving. These are in addition to the ones I've already mentioned, though some are repeated due to importance.
A lot more storage space.
A separate area for our desk and possibly a craft area.
Quiet neighborhood, semi secluded back yard.
good area for cats to transition between mom's place and a town later on.
excellent back deck for container gardening.
utility sink in laundry area (don't know why, I just like them.)
garage for in the winter- no scraping car windows
free pool table (unsure of quality, or presence of balls and stick things)
There are not two complete bedrooms. (but there are more rooms than here. confusing, I know)
Mike would have to bike to school or ride the bus.
basement main room is not finished.
bathroom is upstairs, bedrooms downstairs
basement stairs are a bit steep - this is only a consideration because of kids.
Will add about $100 to our monthly expenditures.
