NEW YORK (CNNMoney) — Consider this one more sign that the housing market is heating up: Appraisers are putting higher values on homes again, allowing for more deals to go through.

During the housing bust, sales were often derailed by low-ball appraisals that fell far shy of a home’s selling price.

For example, if a home cost $500,000 and required a 20% down payment of $100,000, the buyer would need to finance $400,000. But if the appraiser valued the home at $450,000, the buyer would only be eligible for a $360,000 loan — making the home too costly for some buyers.

But now, as home prices climb and housing inventories shrink, appraisers are valuing homes at or above their selling prices, according to Lawrence Yun, chief economist for the National Association of Realtors.
