I've never lived there so I don't know for sure, but I don't think San Francisco would fit within a $200k budget.
Yeah, not so much. I lived there and really had to scrimp to make it on 70k as a single 23 y/o woman; I was still sleeping on an air mattress in my 1850 and 2150/mo apartments while liberally crashing my aunt and uncle's place for meals between paychecks. Don't get me wrong- it is beautiful, and certainly if you are in the internet industry in any way shape or form... it's a hard place to beat.
But there is a reason the city, per capita, has the fewest children/ families of any major metropolitan area in the country.

The Rent is Too Damn High!
Charleston, SC, specifically Mount Pleasant. Your budget is good (it's a 'wealthier' area but still really affordable), some of the best schools in the state (Wando HS is a USNews silver medal school), it's on the coast, sunny and warm most of the year, and taxes are much MUCH lower than Florida in every way.
Couldn't agree more with PapaJohn. I had a lot of classmates (The Citadel) who came from Massachusetts, Maryland, and Georgia and ended up staying in Charleston. The cost of living is comparatively low, there are lots of good schools, great restaurants, very little crime (consider my perspective is shaped by living in Philly, but still), ample culture- amazing views.
If you can get over heat and humidity it's probably the best of all possible worlds.
