However while people in Windsor doesn't have the luxury of high paying jobs that GTA residents have, is it just a temporary fever of buying houses, or there is really something going on in this city ?

What zoning code could I request a zoning variance or rezoning that would allow us to have the 2 livable units on parcel, one primary residence and one additional living unit (known currently as ADU)?

I was preapproved with that amount before, but it was for a single family, primary residence about six months ago.

Similarly, the sale ($575K) minus your adjusted basis determines your capital gain.You may qualify for the primary residence exclusion (up to $250K single/$500K married) if you lived there 2 of the last 5 years.

My idea is to put 20% down on a $1 million property, with the remaining $800,000 paid off over 8–10 years, depending on how much yearly income the seller would want.I’ve seen a lot of discussions about using seller financing for investment properties, but not much when it comes to primary residences.

If you do have to move because of a job, you would be safest (in my opinion, i am not giving legal advice or financial advice), i would sell that property to ensure that you did not just purchase with the goal of moving out early and taking advantage of lower rates and lower down payments for purchasing your home as a primary residence. 

After 25 months, If they can prove that they lived in the property for two of the past five years, they can sell it as an owner-occupied residence.
