3.1 Real Property Appraisal Principles, Valuation, and Classification

Real Property Appraisal Principles, Valuation, and Classification

Read RA 7160 together with RA 12001

The current framework is not the original 1991 text standing alone. Republic Act No. 12001, effective in 2024, is the Real Property Valuation and Assessment Reform Act. It repealed, among others, RA 7160 Sections 199(e), 199(g), 199(o), 212, and 219 and supplied a national valuation framework. Answers that continue to cite the repealed provisions as the current source are outdated even when a familiar concept survived in the new law.

RA 12001 adopts market value as the single valuation base for real-property-related taxes and government transactions. Market value is the estimated amount in an arm's-length exchange on the valuation date between a willing buyer and willing seller acting knowledgeably, prudently, and without compulsion. Valuation must follow the latest Philippine Valuation Standards (PVS), which the BLGF develops and maintains based on international standards.

All real properties, taxable or exempt, are valued at prevailing market values in the locality. Exemption affects taxability, not the assessor's need to discover, list, and value property. Depreciation must be considered for depreciable assets.

From market value to tax

Keep the stages separate:

1. Discovery and listing: identify the parcel, building, improvement, or machinery and the person with the relevant interest.
2. Classification and valuation: determine actual use and estimate market value under the PVS and approved Schedule of Market Values (SMV), where applicable.
3. Assessment: apply the legally authorized assessment level. Assessed value, also called taxable value, equals market value multiplied by the assessment level.
4. Tax computation and billing: apply the lawful tax rate to assessed value.
5. Collection and enforcement: receive payment, issue the prescribed receipt, deposit and account for collections, and use lawful remedies for delinquency.

This sequence explains the division of work. The local assessor performs appraisal and assessment functions. The local treasurer performs billing, collection, custody, accounting for collections, and collection enforcement. The offices coordinate, but one should not silently substitute for the statutory function of the other.

Actual use

RA 7160 Section 217 continues to direct that real property be classified, valued, and assessed on the basis of its actual use, regardless of where it is located, who owns it, or the description in the title. A house actually and predominantly operated as a commercial clinic is not automatically assessed as residential merely because its title or original design says “residential.” Always distinguish actual use from ownership and zoning.

Machinery under the current definition

RA 12001 Section 4(k) defines machinery broadly. It covers machines, equipment, mechanical contrivances, instruments, appliances, or apparatus that may or may not be permanently or temporarily attached. It includes mobile, self-powered, and self-propelled facilities when they are actually, directly, and exclusively used to meet the needs of the particular industry, business, or activity and are designed for or necessary to the listed productive purposes.

Do not reduce that statutory test to physical cementing. Ask what the item is, how it is used, whether the use is actual/direct/exclusive for the activity, and whether its nature and purpose fit the definition.

Revision cycle

RA 12001 Section 19 requires LGUs to update their SMVs within two years from the Act's effectivity. Thereafter, SMVs are updated and general revisions of property assessments and classifications are conducted every three years. Significant market changes, calamities, emergencies, and correction of inequalities have special procedures. This current section replaces reliance on repealed RA 7160 Section 219 as the source for the cycle.

Applying appraisal principles under the RPVARA transition

Republic Act No. 12001 organizes real-property valuation around a single market-value base and uniform valuation standards. Market value is an evidence-based estimate of what property would command in an open and competitive market under the statutory conditions; assessed value is the market value multiplied by the applicable assessment level. Appraisal establishes value, classification identifies the property's actual use, assessment applies the legal percentage, and taxation applies the authorized rate. Keeping those steps separate prevents double counting.

A defensible appraisal records the valuation date, property identity and characteristics, actual use, neighborhood or market area, data sources, method selected, adjustments, and review trail. Comparable sales should be verified and adjusted for material differences rather than averaged mechanically. A cost approach should distinguish replacement or reproduction cost from depreciation. An income approach requires support for income, vacancy, expenses, and capitalization assumptions. Reconciliation is a reasoned conclusion, not an automatic mean of three indications.

Actual use controls classification even when the owner's preferred label, zoning description, or old declaration points elsewhere. At the same time, an assessor must follow the approved schedule of market values and statutory process; field evidence does not authorize an improvised rate. During RPVARA implementation, identify the applicable valuation cycle and approved schedule before computing. Document notice, review, and appeal rights so a value can be reproduced and challenged through the proper channel.
