Personal Value vs. Market Value
An owner may value a highly customized improvement more than typical buyers do. Appraisal value must be supported by market behavior.
Frequently Asked Questions
Does a $100,000 renovation add $100,000 in value?
Not automatically.
Does maintenance count as an improvement?
Replacing a failed system may preserve condition and marketability without creating an equal increase above comparable properties.
Can poor-quality remodeling reduce value?
Yes. Incomplete, unpermitted or poorly executed work can create cost and risk.
Renovations can add enjoyment and utility even when the financial return is less than their cost.
