The differences between market value and appraised value depend on the local market, so they can match, or either one can be higher than the other. In a “seller’s market,” where there is an abundance of buyers, market value will likely sit higher than the appraised value because there’s more demand for the low inventory of homes. In a “buyer’s market,” where there are more homes than there are buyers, the market value is more likely to sit below the appraised value to entice buyers.

While there’s technically no limit to the dollar amount you can borrow for a home addition, the standard limit is around 80% of the value the addition is expected to add to your home. That means you could feasibly borrow up to $80,000 if an appraiser determines that the addition or bump out will add $100,000 in value to your property. You might also be limited by your debt-to-income ratio or credit score.

Mobile homes weigh anywhere between 45 to 50 pounds per square foot. Some newer options weigh up to 70 pounds per square foot. An average single-wide mobile home weighs 45,000 pounds, and a double-wide mobile home weighs about 70,000 pounds. Triple-wide mobile homes range from 90,000 to 100,000 pounds.

While a finished basement adds value to your home, it is assigned a different value than space on the main floors. An appraiser will assess the square footage of a finished basement at about 50% to 60% of the value of the square footage for the rest of your home. Appraisal value for a finished basement depends on your location’s real estate market and the specifics of the basement and how it was finished.
