The 70% rule, and the costs it's protecting you from

The 70% rule is the standard heuristic flippers and wholesalers use to set a maximum offer: pay no more than 70% of the after-repair value minus the repair costs. A property that will be worth $600,000 finished and needs $80,000 of work has a ceiling of $340,000. The 30% the rule holds back is not your profit — it's the buffer that absorbs everything between the purchase and the closing table, and the profit is whatever survives.

The real cost stack. Purchase price and rehab are the two numbers everyone budgets, because they're visible and quoted. Three more quietly eat the margin. Holding costs — property tax, vacant-home insurance (which costs more than a standard policy), utilities, and condo fees — accrue every month you own an empty unit. Financing costs come in two parts: origination points charged once on the loan amount, and interest that accrues for as long as you hold. And selling costs in Canada run around 5% — realtor commission of roughly 5%, plus the GST/HST charged on that commission and your lawyer's fees at closing. That's a lighter selling bill than the 6–8% typical in the US, but it still scales with the sale price, so a higher ARV doesn't raise profit one-for-one.

ARV accuracy is the whole ballgame. Every output on this page — profit, ROI, your maximum offer, your margin — is measured against a number that hasn't happened yet. An ARV that's 10% optimistic doesn't make the deal 10% worse; because the profit is a thin slice of a large number, it can erase the margin entirely. Build the ARV from closed sales of genuinely comparable finished properties in the same neighbourhood, not from listing prices. If the comps are thin, that uncertainty is a reason to bid lower, not to round up. Note too that a flip is generally treated as business income rather than a capital gain — talk to an accountant before you count the profit as yours.

Time is the risk you underestimate. Two of your cost buckets are billed by the month and neither adds a dollar to the ARV. Permits stall, trades move to other jobs, a hidden problem opens behind a wall, and the market takes longer to produce a buyer than your spreadsheet assumed. Model a hold longer than you're hoping for — if the deal only works at four months, it isn't a deal, it's a bet on nothing going wrong. Once the property is finished, compare it against a hold: the cap rate calculator shows what it would earn as a rental, and the BRRRR calculator models refinancing your capital out instead of selling it.

How it works

Estimate the ARV

Enter what the finished property sells for, based on closed comps in the same neighbourhood.

2

Add purchase and rehab

Input the as-is purchase price and your full renovation budget, including contingency.

3

Set hold time and carry

Enter months from closing to closed sale, plus monthly taxes, insurance, utilities, and condo fees.

4

Read profit and your 70% ceiling

Get projected profit, ROI on cash, break-even sale price, and whether your offer clears the 70% rule.

Why selling costs differ in Canada

ComponentTypical share of sale price
Realtor commission~5%
GST/HST on the commissionCharged on top of the commission
Legal fees at closingFlat fee, varies by province
All-in selling cost~5% (vs 6–8% typical in the US)

Lower than US selling costs, which leaves slightly more room in the cost stack. A flip is generally treated as business income rather than a capital gain — confirm with an accountant.

Frequently asked questions

What is the 70% rule in house flipping?+

The 70% rule is a standard heuristic among flippers and wholesalers: pay no more than 70% of a property's after-repair value (ARV) minus the repair costs. On a house with a $300,000 ARV needing $50,000 of work, the maximum offer is $300,000 × 0.70 − $50,000 = $160,000. The 30% that the rule holds back isn't profit — it has to cover holding costs, financing, selling costs, and the mistakes you haven't found yet. What's left after all of that is the profit.

How do you calculate profit on a fix and flip?+

Profit = ARV − total project cost, where total project cost is the purchase price plus the rehab budget plus holding costs plus financing costs plus selling costs. Holding costs are your monthly carry (property tax, insurance, utilities, HOA) multiplied by the months you own it. Financing costs are the origination points (loan amount × points %) plus interest during the hold (loan amount × rate × months ÷ 12). Selling costs are a percentage of the sale price. Skipping any of the last three is the most common way a flip that looked profitable on paper isn't.

What costs do flippers forget to include?+

Almost always the same three: holding costs, financing costs, and selling costs. Purchase price and rehab are visible and easy to budget, so they get the attention. But every month you own the property you pay taxes, insurance, and utilities on an empty house while loan interest accrues — and when you finally sell, agent commissions and closing costs come off the top of the sale price. Together those three can consume a large share of what looked like the margin.

How much are selling costs on a flip?+

In the US, budget roughly 6–8% of the sale price: agent commissions plus title, escrow, transfer taxes, and any concessions you make to the buyer. Because they're charged as a percentage of the sale price, they scale with your ARV — a higher resale price also means a higher selling bill, which is why raising the ARV estimate doesn't raise profit one-for-one.

Why does hold time matter so much on a flip?+

Because two of your cost buckets are charged by the month. Every extra month adds another round of property tax, insurance, and utilities, and another month of interest on the flip loan. Permit delays, contractor scheduling, weather, and a slow market all stretch the timeline, and none of them add anything to the ARV. That's why it's worth running the numbers at a hold time longer than the one you're hoping for — if the deal only works at four months, it isn't really a deal.

What are selling costs on a flip in Canada?+

Budget around 5%: realtor commission (commonly about 5% of the sale price), GST/HST charged on that commission, and legal fees for the closing. That's lower than the typical US 6–8%, which leaves slightly more room in the cost stack — but Canadian flips face their own pressure from higher purchase prices, so the 70% rule ceiling is still worth checking against every offer.
