it should be noted that starting late 1979 - 1982, BoC interest rates were in the 15-20+% range.
they were progressively reduced to low 7+% by early-1987 and only raised to low 14% by mid-1990.
monetary policy was also responsible for the substantial r/e appreciation.
at 15-20%, it would take $1,250-1,600/m to finance $100K for 25 years amortization;
when rates dropped to 7%, it would only take $700 to finance that same $100K.
so of course, people typically look at the monthly payments.
hence, the original $1,250-1,600 would now suddenly be able to finance upto 2.3x what it did before.
thus prices could jump from $100K to $230+K and not change much in monthly payments within a matter of years (1979-1987).
further appreciation was probably fueled by speculation, until rates were increased back to 14% by mid-1990 (in under 3 years) to quell rapid inflation. now that same $230K @ 14% would require upto 65+% more to finance than @ 7%.
interest rates had to be dropped back down to 3-5% by 1997 before r/e sales got any traction again.

similiarities are occurring again as interest rates have been reduced from 14% in mid-1990 to 1% currently.
with rates having no where to go in the long-term but up, and the historical average north of 5%, we're looking for trouble.
