You need to know – What is the sales comparison approach to valuation?

YouNeedToKnowWeb500The sales comparison approach to valuation is based upon the principal of substitution and is one of the three main approaches to value

Used mainly for single family residential properties and vacant land, value is estimated by studying the sale price of similar (comparable) properties, and adjusting the comparables to the characteristics of the subject property

If a comparable is superior to the subject, the comparable value is adjusted downwards

If a comparable is inferior to the subject, the comparable is adjusted upwards

The adjusted prices of the comparable are reconciled into an estimated value of the subject using a weighted average

You need to know – What is the appraisal principle of regression?

YouNeedToKnowWeb500The appraisal principal of regression states that the value of a property is negatively affected by association with an inferior property of the same type

This principal tells us that the value of a high priced property will decrease in value towards the value of less expensive property in the same area

Along with the principal of progression (which has the opposite effect), the principal of regression leads to property prices moving towards a narrow band within the same area

You need to know – What is the appraisal principle of progression?

YouNeedToKnowWeb500The appraisal principal of progression states that the value of a property is positively affected by association with a superior property of the same type

This principal tells us that the value of a low priced property will increase in value towards the value of more expensive properties in the same area

Along with the principal of regression (which has the opposite effect), the principal of progression leads to property prices moving towards a narrow band within the same area
