The rental market in Cornwall
CMHC surveys purpose-built rental apartments and townhouses in buildings with three or more units every October. The median rent was C$1,150, meaning half of surveyed units rented for less. The vacancy rate was 3.5%. The survey covers about 4,168 rental units here. Rents for condos and houses rented by individual owners are often higher and are not included.
What this means for your budget
Average rents mix older and newer homes, so a newly listed home often costs more than the average. Use this figure as a benchmark when you compare listings, and budget for deposits and fees on top. The 30% rule is a simple guide, not a lender's or landlord's requirement; many landlords use their own income checks.
