Blanket Appraisal
A blanket appraisal is a single valuation report that covers several properties at once, used by lenders, developers, and investors to value multiple units, parcels, or buildings under one ownership or financing structure. It is common in pre-construction, where the value can be set years before the deal closes.

What Is a Blanket Appraisal
A blanket appraisal aggregates several properties into one report. Instead of valuing each property individually, the appraiser assesses the group’s shared characteristics, market conditions, and income potential to determine a combined value. Lenders use it to streamline financing for borrowers buying or holding multiple properties under a single facility.
Blanket appraisals are common in development projects, multi-unit buildings, land assemblies, and pre-construction condominiums. In these cases, the valuation can be completed years before closing, so the contract value may no longer match the current market value when the deal actually closes.
Why Blanket Appraisals Matter for Mortgages
A blanket appraisal provides lenders with a single estimate of the total collateral backing multi-property financing. In pre-construction, it can prevent an appraisal gap when prices soften after the purchase date, since a buyer who agreed to a higher price may rely on the earlier valuation to avoid a closing shortfall.
The flip side is that an outdated valuation can mask real changes in value, leaving a lender relying on collateral that looks stronger than it is. OSFI has flagged this timing mismatch and expects lenders to “establish policies ensuring timely, realistic, and substantiated valuations.” When many units are financed at stale values, the risk can build across the book’s loan-to-value ratio.
How Blanket Appraisals Compare to Other Appraisal Types
A blanket appraisal sits alongside other valuation approaches.
Individual property appraisals. An appraisal of a single property is the standard for a typical residential mortgage. It is detailed and property-specific, but inefficient when many properties are financed under one loan.
Portfolio appraisals. A portfolio appraisal values a group of income-producing properties owned by one borrower. A blanket appraisal is similar but may include a wider mix of properties or pre-construction units tied to a single financing structure.
Development or construction appraisals. A construction appraisal focuses on project plans, land value, and the completed building’s future value. A blanket appraisal can be used in development, but it does not always include the as-complete method unless the lender requests it.
When you buy a pre-construction condo for $600,000 in 2021, with a blanket appraisal for the whole building. By the 2025 closing, the market value has slipped to $540,000. The blanket appraisal allows the lender to rely on the earlier figure, but an updated individual appraisal would reveal a $60,000 gap that you would need to cover at closing.
Common Mistakes and Misunderstandings About Blanket Appraisals

- Assuming lenders prefer blanket appraisals for every multi-property mortgage
- Forgetting that lender approval is needed before ordering one
- Underestimating the timing gap between contract value and closing in pre-construction
- Assuming a blanket appraisal lowers appraisal costs in every case

Frequently Asked Questions (FAQ) About Blanket Appraisals
Why are blanket appraisals used in pre-construction condominiums?
They give lenders a single valuation for all units in a building so that financing can be streamlined and units priced based on values agreed years earlier.
Can a blanket appraisal hide a decline in market value?
Yes. If a lender continues to rely on a valuation completed before prices softened, the report can mask the current value and create a timing mismatch at closing.
What is the difference between a blanket appraisal and an individual appraisal?
A blanket appraisal values several properties in one report, while an individual appraisal values a single property. The individual approach is more property-specific and up to date.
Do blanket appraisals increase risk in Canada?
Blanket appraisals can increase lender and borrower risk. Regulators have noted that outdated valuations may overstate collateral, particularly in volatile pre-construction markets, which raises risk for lenders and buyers alike.
Do lenders always accept blanket appraisals?
No, lender policies vary on blanket appraisals. Some lenders accept them for multi-property or pre-construction financing, while others require updated individual valuations to reflect current conditions.
