Great questions everyone. I think we should probably be closer to downtown, but between the two of us, based on the factors that you've raised. Thanks for your responses - we looked at houses today.
I've lived in two different big cities, I would say live as close to your downtown office as possible and let him have a reverse commute. Since he is also a business owner, a chunk of his transportation costs are a direct business expenses verses yours paid with after-tax dollars.
This is a very good point. A longer commute for me is more money out of our pockets. We aren't looking to retire early, but we would like financial independence.
Why have you ruled out DH relocating his business closer to the city?
It's really in the best location. The company serves the higher end of the market, and those lovely antimustachians live close to his business. Plus, the location is close to neighboring counties, where they also work. If the business moved closer to the city, that would just mean more trucks, vans, equipment, etc traveling from the business to the sites. (It's a medium size business, about 50 employees). Other locations were looked at, but the tax rates are better (we pay A LOT of taxes), DH got a great deal on the building, DH has other tenants who pay well, blah blah blah.
Traffic wise is there more going into the city or out of the city at morning rush hour? Or is it about equal? The same for evening? If there is lighter traffic one direction then I would choose to live closer to the end with heavy traffic leaving the long commute for the one with the lighter traffic. If traffic is equal, split the difference. The shorter the commute the better it will be once children arrive. So, if you find 2 house you like and one has a 30 min commute and one a 45, pick the shorter commute.
Definitely heavier traffic with my commute. We found two houses that we like - one with a 15 minute commute for me (35 for him) and another with a 30 minute commute for me (12 for him). I'm leaning towards the first.
A lot of comments about kids - my mom will be our full time nanny, and DH's parents are in town as well. My FIL is a retired, full time grandpa. We are very fortunate.
