How Comparable Sales Affect Your Property's Value

What Is a Comparable Sale?

A comparable is a property similar to yours that has recently changed hands, used as evidence of what the market will pay. The closer a comp matches your property, the more reliable it is. Appraisers look for comps that are:

• Recently sold — actual closed sales, not just listings or asking prices
• Nearby — ideally the same subdivision or barangay, where the market is truly comparable
• The same type — a house-and-lot is compared to other houses-and-lots, a condo to other condos
• Similar in size — comparable lot area and floor area
• Similar in age and condition

A listing tells you what a seller hopes to get. A closed sale tells you what a buyer was actually willing to pay — which is why sold comps carry far more weight.

How Comps Are Used to Value Your Property

Appraisers arrive at a value through the Sales Comparison Approach — a structured, three-step process.

Step 1 — Select the comps

The appraiser gathers three to six recent sales that are as similar to your property as possible, in your immediate area.

Step 2 — Adjust each comp to match yours

No two properties are identical, so each comp's sale price is adjusted up or down to account for its differences from yours. The rule is simple:

• If a comp is better than your property (bigger lot, renovated, corner location), its price is adjusted down to reflect your property.
• If a comp is worse than yours (older, smaller, needs repairs), its price is adjusted up.

Common adjustment factors include lot area, floor area, location within the area, age and condition, amenities, whether the property is tenanted, and how long ago the sale happened.

Step 3 — Reconcile into a single value

After adjustment, the comps cluster into a range. The appraiser gives the most weight to the comps that needed the fewest adjustments — the ones most similar to yours — and reconciles them into a single indicated value. This is often expressed as a value per square meter, then applied to your property's area.

Why the Sales Comparison Approach Outweighs the Cost Approach

Appraisers can use more than one method. Two of the most common are:

• Sales Comparison Approach — value based on what buyers actually paid for similar properties.
• Cost Approach — the value of the land plus what it would cost to build the improvement (the house or building) new today, less depreciation for age, wear, and outdated design.

When both are used, the appraiser reconciles them — and for typical residential and commercial resale properties, the sales comparison approach is given the stronger weight. The reason: it reflects real market behavior, while the cost approach depends on estimated construction costs and a judgment about how much value the building has lost to depreciation.

The cost approach is a valuable cross-check, and it takes the lead in special cases — brand-new construction, or special-purpose properties (churches, schools, unique structures) where there are few or no comparable sales. But where a real market of comparable sales exists, that market is the best evidence of value.

Why the Appraisal May Feel Lower Than What You Spent

Many owners are surprised when the appraised value comes in below what they invested in their home. This is one of the most common — and most understandable — reactions. The key idea is this: what you spent is not automatically what the market will pay.

• Cost is not value. Your construction receipts show what it cost you to build. The appraisal reflects what a buyer would pay — and buyers set prices by comparing to other properties, not by reading your invoices.
• Over-improvement. A high-spec home in a modest neighborhood rarely recovers its full cost. The surrounding market caps what buyers will pay, no matter how much was spent.
• Personal or custom features. Highly specific finishes, unusual layouts, or custom design suit your taste but may not add market value — and can even count as functional obsolescence if buyers see them as something to change.
• Depreciation. Finishes and materials age. The market values the property's current condition, not its original cost when new.

None of this means the money was wasted — you enjoyed the home. It simply means market value is measured against real, comparable sales, which is exactly why the sales comparison approach is weighted so heavily.

The Upside: You Can Compete Fairly in the Market

Because a comps-based appraisal is built from the same market evidence that buyers and other sellers use, it gives you a value you can actually sell against. That is a real advantage when you list your property:

• Price to compete. You can set an asking price that stands shoulder-to-shoulder with similar properties in your area — neither scaring buyers off with an overpriced listing nor leaving money on the table.
• Attract serious buyers. A realistic, evidence-backed price draws buyers and their agents, who compare your property against the same comps.
• Negotiate from strength. When your price is backed by actual sales, you can defend it — instead of guessing or backing down.
• Sell faster. Fairly priced properties move; overpriced ones sit on the market and often sell for less in the end.

What You Can Do

• Keep records of major improvements and their dates — they help the appraiser assess condition accurately.
• Have your title (TCT/CCT) and tax declaration ready.
• Point out upgrades that a buyer would value (structural, not just cosmetic or personal).
• Give the appraiser full access during inspection so nothing that adds value is missed.
