Formula
Price = SqftValue x BedroomMult x BathroomMult x AgeMult
Home price is estimated by calculating base square footage value (with diminishing marginal returns for larger homes), then applying multipliers for bedroom count optimization, bathroom-to-bedroom ratio, and age depreciation/appreciation. Location tier sets the base price per square foot from which all calculations derive.
Worked Examples
Example 1: Suburban Family Home
Problem:Estimate the price of a 2,200 sqft, 4-bed/2.5-bath suburban home built in 2005.
Solution:Base PSF (suburban): $175. Sqft value: 1500 x $175 + 700 x $175 x 0.85 = $262,500 + $104,125 = $366,625. Bedroom multiplier (4 beds): 1.05. Bathroom ratio 2.5/4 = 0.625 -> multiplier: 1.0. Age: 20 years -> multiplier: 0.975. Estimated: $366,625 x 1.05 x 1.0 x 0.975 = $375,350. Range: $319,000 - $432,000.
Result:Estimated: $375,350 | $171/sqft | Range: $319K-$432K | Monthly: ~$2,350
Example 2: Urban Condo
Problem:A 950 sqft, 2-bed/1-bath urban unit built in 2018.
Solution:Base PSF (urban): $280. Sqft value: 950 x $280 = $266,000. Bedroom multiplier (2 beds): 0.95. Bath ratio 1/2 = 0.5 -> multiplier: 1.0. Age: 7 years -> multiplier: 1.0. Estimated: $266,000 x 0.95 x 1.0 x 1.0 = $252,700. Effective PSF: $266. Range: $215K - $291K.
Result:Estimated: $252,700 | $266/sqft | Range: $215K-$291K | Monthly: ~$1,580
Frequently Asked Questions
What features have the biggest impact on house price?
Research consistently shows that location is the single largest factor, accounting for 30-50% of a home value. After location, square footage is the next most important feature, typically explaining 20-30% of price variation. Bedroom count, bathroom count, and lot size each contribute 5-10%. Age and condition matter but less than most people assume — a well-maintained 30-year-old home in a great location outprices a new home in a mediocre area. House Price Estimator Features Based focuses on physical features but remember that school district quality, crime rates, proximity to employment centers, and neighborhood desirability are the invisible forces that set the baseline price per square foot.
How accurate are feature-based price estimates compared to actual market prices?
Feature-based estimates (also called hedonic pricing models) typically achieve accuracy within 10-20% of actual sale prices when calibrated to local market data. Professional appraisals using comparable sales achieve 5-10% accuracy. Zillow Zestimate, which uses ML on millions of data points, achieves about 7% median error nationally. The main limitation of feature-based models is that they cannot capture hyperlocal factors: the house backing onto a busy road vs. a quiet cul-de-sac, views, specific school attendance zones, or unique renovation quality. Use this estimate as a starting point and adjust based on comparable sales in your specific neighborhood.
