Hard to find, but Cessna 205 is cheaper than 210 or 206.

I'm a new pilot (passed my checkride last Saturday). I have a wife and
three small children (all 6yrs and under).

Weight and balance would be OK to fit three kids in back of a 172, and
it
looks like plenty of space (at least while they're young). Is it
possible
to get a STC to install a third seatbelt?

No.



If not, is there any other fixed-gear single in a similar price range
that
could accomodate 5?

No. An option is a third childs seat in the baggage area but it's a
pretty
bad seat and would allow no luggage to be carried. You're gonna need a
206,
get your checkbook out.
