Affordability & Mortgage
Income needed assumes a ~32% GDS ratio; weekly is mortgage principal & interest only. Price ÷ income is the home price over the income needed. Fixed reference assumptions so listings compare on equal footing, not a lending decision.

Investor snapshot
The suite is real income here: basements rent in Kleinburg (26 of 173 recent detached leases were basement units, around $2,050 a month). The figure above is the whole house on one lease; rented as two units, the suite alone brings about $2,050 a month on top of the upper floors. Permitted use is worth confirming with the city.
Thinking of this home as an investment? We will pull real comparable rents and run the full numbers with you.
Talk about the numbersThe last 25 whole-home leases in Kleinburg signed at a median of $6,206 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $7,069. The gross yield above is on the asking price, before taxes and upkeep; the cap rate is after them. A finished basement or second suite can push real rent above it. Taxes, fees, and vacancy vary by property, and cap rate is before financing.
