Two different numbers, easily confused
Market value is what your home would sell for: land, location, comparable sales, and current buyer demand all factor in. Replacement cost is what it would actually cost to rebuild the structure from the ground up, at today’s construction prices, with no relationship to what the property would fetch on the market. Homeowners regularly assume these two numbers track each other. On a luxury Ohio property, they often don’t, in either direction.
Where the two numbers diverge
A custom home on a small in-town lot, in a neighborhood like German Village or Victorian Village, can have a market value driven heavily by location and land scarcity, while its actual rebuild cost, stone, custom millwork, period-appropriate materials, runs well above what the market value alone would suggest. The reverse happens too: a large custom estate on acreage in a less land-constrained market can have a rebuild cost that outpaces its market value, since construction cost doesn’t discount for a softer local resale market the way a sale price would.
Insuring to market value in either direction is a mistake. Insure to a market-value number that’s too low, relative to rebuild cost, and a total loss leaves you short of what it actually costs to rebuild. Insure to market value when it’s inflated relative to rebuild cost, and you’re simply paying premium on coverage you’ll never use.

Why this matters more for custom and luxury homes
Production homes in standard developments have market values and rebuild costs that stay reasonably close, since comparable sales and comparable construction costs move together. Custom homes break that relationship, precisely because there’s nothing directly comparable to price either number against.
Your home’s insurance number and your home’s sale number answer two completely different questions. Only one of them matters when you’re rebuilding.
Getting the right number
A full asset review prices your dwelling coverage against actual construction cost, not an appraisal or market estimate, which is the only number that matters when a policy actually has to pay for a rebuild.
