- Major Renovations: Complete remodels of kitchens or bathrooms often lead to higher valuations.
- Swimming Pools: Installing a pool is considered a luxury upgrade that can increase property value.
- Energy-Efficient Upgrades: Adding solar panels or energy-efficient windows can also impact the property’s assessed value.
