"Elmer was very professional on my land appraisal. He made two trips to the planning department in order to determine the highest and best use of my land based on San Jose's zoning and building requirements. Elmer was very easy to contact by phone. He always answered his phone or readily called me back. I would gladly use him to do any future appraisals."

Property Appraiser FAQs, answered by experts

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.

Whether a scullery is worth it depends on how much you like to cook and entertain. If you frequently host gatherings—a scullery is likely worth the money. If you’re looking for ROI, it’s not so clear. It may not add significant value to your home, as it doesn’t increase square footage and may repurpose space that a buyer would have preferred to remain as-is (like a laundry room). 

Yes, built-in bookshelves can be worth the investment and can add value to your home, especially when constructed from high-quality, timeless materials like luxury hardwood. They offer a practical and stylish storage solution that utilizes wall space effectively. While they cost more than store-bought units, the custom fit and potential to increase your property's resale value make them a desirable feature for many buyers, particularly for homeowners with large book collections. For the best return on investment, consider having them professionally built.

If installing board and batten fixes an issue with the home, it could increase the value, but it isn’t commonly installed for that purpose. Board and batten is an aesthetic choice and, like most aesthetic choices, will do little to raise your home’s value. That being said, certain design elements can help attract more buyers, even if your home’s price won’t see a noticeable bump.
