Guest house, big shop, or extra land? These homes get overpriced fast.
• Price the main house first, then adjust for the extra feature using local comps.
• Build cost is not resale value. Buyers rarely pay dollar for dollar for a new shop or cottage.
• Extra land adds more when it is usable, private, and easy to access.
• The more niche the feature, the more believable the price needs to be.
In Clark County and nearby Oregon, I price unique homes by buyer behavior, not wishful math. If you want a second opinion, I’m happy to help.
