My kids would not be MAKING THE DECISION NO WAY. But they would have say in *some* things--like let's say they were old enough to want a family room separate from a living room to go into with friends and be separate from the adults. OK, sure.
My kids, though they haven't stated this themselves, would benefit immensely from a fenced-in yard. So I will be looking for a large fenced-in yard.
We're PG with #4. We have two boys and a girl currently. Eventually they are probably not going to want to share a bedroom with the opposite gender. I'll keep that in mind and make sure I have space to add a bedroom if one does not exist. (given our current family composition, that means we need 4 bedrooms--a 'girl room' a 'boy room' my mom's and Mine and DH's room.)
There's a particular area I'd like to move to so the kids can walk to school. It's also located near a small, not used a ton, park that we could go to.
Things like SIZES of these rooms...not so much a consideration I'll listen to. Within reason--I get wanting a room bigger than a *closet*.
If they didn't want a room on a separate level from US yet for sleeping, I'd make sure the house could accomodate that.
But no, they don't get to pick the 'style' of the house. And I'd remind them that if we OWN this house, we can PAINT THE ROOMS any color we want! Also random location choices like living near friends--friends move and change.
Now for us with *four* kids living near their school so we can walk to it might be a great consideration. For someone with *one* kid...if they really liked the neighborhood, OK. If it was near schools they liked for *all* of the child's education, OK. If they don't, school is 6 years for elem. 3 for middle, 4 for high school--all relatively short periods of time when you are thinking about a mortgage.
IT's OUR house, we as the parents have to like it. (an example, *I* as cheif floor cleaner, want NO carpet.
the kids don't get to say they don't like that. Tough. YOU don't have to try to keep carpet decent. I HATE carpet.)
So what would ultimately happen is I'd take my kids' opinions into consideration on some things, but they would NOT get a veto for "silly" reasons--and I would not be looking at houses that did not meet our major requirements. (currently, 4 bedrooms or a way to add a 4th easily, like a finished basement, a room or area to be used as indoor playspace in the winter--could even be that 4th bedroom for the time that they don't care about all sleeping in one room. And yard space. Preferably already fenced. Oh, and a location not right on a "main drag.")
So no, in the end, with all that taken into consideration, no, the children do NOT make the final decision.
