Wow, I didn't really the madness goes all the way up there. Any idea who are those buyers (local or from oversea)?
We're the next best option for those moving out of the city. When the developer opened about 7 years ago, most were from Woodbridge, Mississauga, Richmond Hill and Newmarket.
Five minutes to the 400, 20 minutes to Barrie, 10 minutes to Newmarket and we have a GO station.
I'm not sure the demographics of the resale buyers. So far the house across the street was bought by an Asian couple with no kids. They look to be our age (late 30's), both drive Mercedes and they spent a month renovating before they moved in. They renovated a new house, yes.
Same with our friends house up the street, same scenario but his family has young kids.
The demographic for Bradford was predominantly white with a fairly large Portuguese population and Italian when the new homes started.
The last couple of years Bradford looks more like a typical GTA town, more diverse.
Those that are leaving Bradford from our neighbourhood seem to be cashing in and moving further North. Innisfil, Barrie etc.
We bought in 2011 for $349 and as of last January when new phases were released, our model is up to $505. Our next door neighbour who just sold for $629 paid $369 in 2011.
Yes, in Bradford, Ontario.

In a town that had 18000 before the developers showed up will have added something like 3000 homes in 8 years. Our developer is closing in 3 years and will have built 1200 homes in 10 years.
Edited to actually answer your question

They all seem like they've just moved from elsewhere in the GTA. Some neighbours I spoke to that moved from Woodbridge etc have done this before. Buy a new home before the ground has broken, live there a couple of years rinse, repeat a bit further North.
I'm pretty sure the diversity in our town now is just people moving from the GTA rather than completely new Canadians or investors.
