What Does a Home Appraiser Look For? The Complete Methodology
Home appraisers visit 30-90 minutes: measure sq footage, document rooms, photograph interior/exterior, note condition and updates. Comp selection: 3+ comparable sales within 3-6 months, within 1 mile (urban) to 10 miles (rural). Common adjustments: extra bathroom +$5K-$15K; garage +$8K-$20K; pool +$10K-$50K+ (climate-dependent); sq ft +$50-$150/sq ft. Condition matters more than cosmetics. Updates valued at less than their cost. Appraiser is licensed by the state; Appraiser Independence Requirements prevent lender influence. Own Luxury Homes® 12-Point Agent Integrity Audit™.
What Does a Home Appraiser Look For? The Complete Methodology
Understanding exactly what an appraiser evaluates during the visit — and how they translate those observations into a dollar value — gives buyers and sellers meaningful insight into the process.
The Physical Visit: What the Appraiser Documents
An appraiser's physical visit typically runs 30–90 minutes for an average single-family home. During the visit, the appraiser: Measures square footage: exterior measurements are taken (and compared against tax records, which are sometimes wrong). Interior room count and size are documented. Documents all rooms: bedroom count and size, bathroom count (full = sink/toilet/tub or shower; half = sink/toilet only; three-quarter = sink/toilet/shower), kitchen features, living areas, basement (finished vs unfinished), garage (attached/detached, size). Photographs: exterior (all four sides, street view, driveway), interior (kitchen, all baths, living areas, any updates), any notable features or deficiencies. Notes condition: overall condition on a C1–C6 scale (C1 = new construction; C6 = poor condition requiring major work). Also notes quality of construction on a Q1–Q6 scale (Q1 = exceptional; Q6 = below-grade construction). Identifies any issues: visible deficiencies, deferred maintenance, FHA/VA minimum property requirement issues (broken windows, exposed wiring, roof condition, water damage signs).
How Appraisers Select Comparable Sales
After the physical visit, the appraiser researches comparable sales ("comps") — similar homes that have sold recently in the area. The selection criteria: Recency: ideally within the last 3 months; up to 6 months is acceptable; beyond 6 months requires market condition adjustments and lender approval for use. Proximity: within 1 mile in urban/suburban markets; up to 5–10 miles in rural markets with limited sales. The appraiser must use the most similar available comps, not just the most convenient ones. Similarity: similar style (single-family vs condo), similar size (typically within 20–25% of subject), similar bedroom/bath count, similar lot size and features. The appraiser selects a minimum of 3 comparables and typically uses 3–5. If no highly similar comps are available (a unique property, low-sales-volume market, or unusual features), the appraiser must use less similar comps and make larger adjustments — which introduces more subjectivity and risk of error.
Dollar Adjustments: What Features Are Worth
For each comparable sale, the appraiser adds or subtracts dollar adjustments for differences between that comp and the subject property. These adjustments are based on paired sales analysis and market data: Extra bathroom: +$5,000–15,000 (varies by market; higher-value markets show higher bathroom premiums) Garage (comp has no garage; subject has one): +$8,000–20,000 depending on market and garage size Pool: highly variable. +$10,000–50,000+ in warm climates (Florida, California, Arizona); minimal or even negative value in cold climates where maintenance costs exceed demand Square footage: typically $50–150/sq ft depending on market price level Lot size premium: highly market-dependent; rural markets value acreage more than suburban Condition/updates: a kitchen or bath renovation adds value, but typically at 50–80% of renovation cost — not dollar-for-dollar Individual adjustments greater than 10% of sale price or net adjustments greater than 15% require additional justification. Appraisers with large adjustments are more likely to face scrutiny in a Reconsideration of Value review.
“The most common misconception I see sellers have before an appraisal is that the improvements they spent money on will come back dollar-for-dollar. They almost never do. A $35,000 kitchen renovation might produce a $15,000–20,000 adjustment in the appraisal. That does not mean the renovation was not worth doing — it may have helped the home sell faster and at a higher price overall. But the appraisal adjustment process values market-based evidence of feature premiums, not renovation receipts. Understanding this helps sellers prepare realistic expectations and focus on what actually moves the needle in an appraisal.”

How long does a home appraisal take?
The physical property visit takes 30–90 minutes for an average single-family home. Larger, more complex, or unique properties take longer. The appraiser then researches comparables, writes the report, and submits it — a process that typically takes 3–7 business days from the visit. Total time from ordering the appraisal to receiving the report is typically 7–14 days. Rush appraisals are available from some appraisers for an additional fee.
Do appraisers look inside the house?
Yes. A traditional full appraisal involves an interior inspection. The appraiser documents all rooms, measures square footage, photographs interior conditions, and notes any deficiencies. Desktop appraisals (using existing data without a physical visit) and hybrid appraisals (third-party inspector visits; appraiser works from photos and data) are alternatives approved for some loan types, particularly conventional loans for refinances. FHA and VA loans generally require a full interior inspection with specific minimum property requirements.
