There are several different ways to increase a property's value. In no specific order, you could: build an addition to your house, thereby increasing its size; finish the basement, thereby increasing its livable square footage; change out the exterior materials (like from wood or vinyl siding to stucco or brick, etc.); remodel certain rooms in the house (like especially the kitchen and master bedroom/bathroom); or even just update the house in general (like new carpet/tile/hardwood floors, paint, appliances, lighting and plumbing fixtures, etc.). Any of those items would increase a home's value. (If you're selling, home staging could temporarily increase a home's "perceived" value as well.)
