Appraisal — at a glance

A real estate appraisal is an independent, professional valuation of a property prepared by a licensed appraiser. Appraisals are required on virtually every real estate loan because the lender needs an objective determination of value to size the loan, calculate LTV, and manage collateral risk.

Formula

How Appraisal is calculated

Appraised Value = Reconciled value from: Sales Comparison + Income Approach + Cost Approach
Sales Comparison
Recent sales of similar properties, adjusted for differences.
Income Approach
NOI ÷ market cap rate — used on income-producing commercial.
Cost Approach
Land value + replacement cost – depreciation — used on special-purpose and new construction.
In depth

What Appraisal actually means in practice

Residential appraisals use the sales comparison approach as the dominant method: the appraiser identifies 3–6 recent closed sales of similar properties in the same submarket, adjusts each comp for differences (size, condition, bed/bath count, lot size, etc.), and arrives at an indicated value range. The appraiser then reconciles the comps to a single indicated value — typically the figure that becomes the appraised value used by the lender.

Commercial appraisals use the income approach as the dominant method. The appraiser projects stabilized NOI based on market rents, vacancy, and expense norms, then applies a market cap rate to arrive at a value indication. The income approach is reconciled with sales comparison (recent commercial trades) and sometimes cost approach (replacement cost) to arrive at the final value.

Appraisal disputes are common when an appraisal comes in below the contracted purchase price or the borrower's expectation. Most lenders have a formal appeal process — the borrower can submit additional comps, raise factual errors, or request reconsideration of value. Successful appeals are common but not guaranteed; the appraiser has final authority on the report.

On commercial bridge and construction loans, the appraiser typically provides multiple values: as-is value (current condition), as-completed value (after the proposed work is finished), and as-stabilized value (at stabilized occupancy / rents post-completion). The loan amount typically caps at percentages of each value — usually with the most conservative being the binding constraint.

Worked example

Worked example: multifamily appraisal triangulation

Property: 18-unit Class B multifamily
Income Approach
Stabilized NOI / market cap rate$2,340,000
Sales Comparison Approach
Avg price/unit × 18 (per recent comps)$2,280,000
Cost Approach
Replacement cost – depreciation + land$2,440,000
Reconciled appraised value$2,300,000
Loan @ 70% LTV$1,610,000
Result: The appraiser typically weights the income approach most heavily on stabilized income property, reconciling between methods to a final value.

Why it matters

The five things to remember about Appraisal

Appraisal sets the value that drives LTV and loan amount.
Residential uses sales comparison; commercial uses income approach.
Bridge / construction loans get as-is + as-completed + as-stabilized values.
Appraisal disputes can be appealed but appraiser has final authority.
Low appraisal can re-cut a deal or kill it at the closing table.

FAQ

Common questions about Appraisal

How much does a real estate appraisal cost?

Residential: $400–700. Small multifamily (5–20 unit): $1,200–3,000. Mid-market commercial: $3,500–8,000. Large institutional: $10,000–25,000+. The borrower typically pays the appraisal fee.

What's the difference between appraisal and BPO?

An appraisal is a full report by a licensed appraiser, USPAP-compliant, valid for lending. A BPO (Broker Price Opinion) is a less formal value estimate by a real estate broker — usable internally by lenders for some purposes but not as a substitute for an appraisal on most loans.

What happens if the appraisal comes in low?

Three options: borrower brings additional equity to close, the deal is restructured (smaller loan, renegotiated price), or the appraisal is appealed with additional comps. Appraisal appeals succeed maybe 25–40% of the time on legitimate comp grounds.

What's the difference between the three appraisal approaches?

Sales comparison uses recent comp sales; best for residential. Income approach uses NOI ÷ cap rate; best for income-producing commercial. Cost approach uses replacement cost; best for special-purpose properties and new construction.

Can I share my own market analysis with the appraiser?

Yes, but the appraiser is required to maintain independence. You can submit comps and market data; the appraiser will consider them but retains professional judgment on the final value.
