Home value, equity and assessment questions
Short, sourced answers to what Canadians ask most: how much equity you can take out, appraisal vs assessment, low appraisals, assessment appeals and the 90% secondary-suite refinance.
Frequently asked questions
How much equity can I take out of my home in Canada?
Usually up to 80% of the appraised value minus what you owe; a HELOC's revolving part can be at most 65% of value.
What's the difference between an appraisal and an assessment?
An appraisal is a qualified appraiser's market-value opinion on a date, used by lenders. An assessment is your assessor's value for property tax, as of a set valuation date that can be years old.
Can Revalued.ca tell me what my home is worth?
No. We never estimate a specific property's value. Our tools test what a value you bring (an estimate, assessment, AVM or appraisal) would unlock, and arrange comparables you enter.
My appraisal came in low. What can I do?
Ask the lender to have the appraiser reconsider with better comparables and corrected facts, try another lender, or restructure the plan. An AIC complaint reviews professional standards only; it can't change the value.
How do I appeal my property assessment?
Each province has its own first step and deadline: Ontario's free Request for Reconsideration with MPAC, BC's Notice of Complaint by January 31, 30 days in New Brunswick, 31 in Nova Scotia, 60 in Newfoundland and Labrador. See our province guides.
Can I refinance to 90%?
Only to add housing units: since January 15, 2025, an insured refinance can go up to 90% of the value after completion, up to $2 million and four units. Other refinances stop at 80%.
