Before You Decide

Worth reading first

Short guides that explain the why behind the numbers — so you actually understand your result.

Why Duitora

Financial clarity,
no strings attached

No upsells for financial products. No premium tiers. No catch.

Real simulation, not a rule of thumb

Every calculator runs a month-by-month model for up to 30 years — tracking mortgage amortization, property tax growth, rent escalation, equity accumulation, and the investment return on your down payment simultaneously. No back-of-envelope estimates.

Your numbers never leave your browser

No account, no sign-up, no tracking of what you enter. Every calculation runs locally in your browser. We can't see your income, your home price, or your down payment — because we never receive them.

Both markets, fully built out

Not a US calculator with a currency toggle. Canada gets the stress test (contract rate + 2%), CMHC premiums by down payment tier, land transfer tax by province, first-time buyer rebates, FHSA and Home Buyers' Plan — all calculated automatically.

Common Questions

Before you decide

Answers to the questions most buyers and renters get wrong.

There's no universal answer — it depends on your timeline, your local market, and what you'd do with your down payment if you didn't buy. In most US and Canadian cities you need to stay at least 5–8 years for buying to beat renting on a pure cost basis. Run the Rent vs. Buy calculator with your actual numbers to find your break-even point.
Your bank will approve you for the maximum you qualify for — not the maximum you can comfortably afford. A common mistake is using gross income and forgetting property tax, maintenance, and insurance. The Home Affordability calculator shows three tiers (Conservative, Comfortable, Maximum) based on your take-home pay.
In the US, 3% is the minimum for most conventional loans (20% avoids PMI). In Canada, the minimum is 5% on homes under $500K, scaling to 10% on the portion between $500K–$999K — and CMHC mortgage insurance is required below 20%. A larger down payment lowers your monthly payment but ties up capital that could be invested elsewhere.
"Is now a good time?" is almost always the wrong question. The right question is whether it makes sense for your timeline and finances at current prices and rates. Markets that look expensive can still favor buying if you're staying 10+ years. Check today's rates, then model your specific scenario in the calculator — that's more useful than any macro prediction.
Refinancing saves you money only if you stay long enough to recover the closing costs through your monthly savings. A common rule of thumb is "refinance if rates drop 1%," but that ignores how long you plan to stay. The Refinance Break-Even calculator finds your exact payback month so you can decide whether to refinance now or wait for rates to drop further.
Yes — Canada is fully built out, not just a currency toggle. The Rent vs. Buy calculator includes the mortgage stress test (qualifying at contract rate + 2%), CMHC insurance premiums by down payment tier, land transfer tax by province, and first-time buyer rebates. The FHSA and Home Buyers' Plan are covered in the Canadian pre-approval guide.
