What is the correct adjustment when comparing properties with different numbers of bedrooms?

When determining the value adjustment for properties with different numbers of bedrooms, it is essential to reflect the market value objectively based on the added utility and desirability that a bedroom provides. Valuing the additional bedroom at $10,000 is considered a reasonable assessment in many markets, as it recognizes that an extra bedroom increases a property's value significantly. This amount is based on factors such as local market conditions, buyer preferences, and the overall demand for homes with more sleeping space.

In contexts where additional bedrooms provide clear advantages such as increased space for families or the ability to use a room for offices or guest rooms, pricing the additional bedroom at $10,000 aligns with how buyers might perceive value. This value accounts for construction cost, market demand, and the typical appreciation associated with residential properties that offer more living space.

In contrast, lower values (like $5,000) might underestimate the real estate market's willingness to pay for extra bedrooms, while higher values (like $15,000) could overestimate the demand or restrict the property's price in a competitive market. The notion of no adjustment also overlooks the significant role that the number of bedrooms can play in assessing property value.
