BRRRR is one of the most powerful real estate wealth-building strategies available to Canadian investors. By purchasing distressed properties below market value, renovating to force appreciation, then refinancing to recycle your capital, you can build a rental portfolio without tying up capital indefinitely.
Canadian-specific rules matter: Investment properties require a minimum 20% down payment — CMHC mortgage default insurance is not available for non-owner-occupied properties. On refinance, most Canadian lenders cap the LTV at 75–80% for investment properties, and the OSFI stress test applies (you must qualify at your rate + 2%, or 5.25%, whichever is higher).
Rental income counting: lenders typically use 50% of gross rental income in TDS/GDS calculations. Some B-lenders and private lenders count up to 80–100%. This affects how much you can borrow on subsequent properties.
Run the numbers before you buy, sell, or invest — estimate payments, taxes, affordability, and potential returns in seconds.
A BRRRR deal works when the refinance (usually 75% to 80% of the after-repair value) returns most or all of your original cash, leaving the property cash-flow positive with little or no money left in. Enter the price, rehab budget and ARV to see the result.
The calculator adds the purchase price, closing costs, renovation and holding costs, then refinances at your chosen loan-to-value on the after-repair value. The cash left in the deal is your total spend minus the refinance proceeds after paying off the first loan. Rental income and the new mortgage show the post-refinance cash flow.

Buy, Rehab, Rent, Refinance, Repeat: buy a distressed property, renovate it, rent it, refinance to pull your cash out, then repeat.
Most conventional lenders refinance rentals up to 75% to 80% of the appraised value. Alternative lenders may differ.
Lenders use a portion of expected rent (often 50% to 100%) together with your other income, depending on the program.
Borrowed money is not income, but interest deductibility and capital gains rules depend on how you use it. Check with your accountant.
