How appraisers value homes in a hot housing market

Didier Malagies • May 13, 2021


Robin Sheridan, a real-estate broker with Compass Washington, recently listed a three-bedroom home in Seattle for $795,000. The 76-year-old brick home had what Sheridan considered a “funky layout,” with two rooms added to the back that didn’t quite integrate into the flow of the home. Still, they functioned well as office spaces.


Sheridan received 29 offers on the property, which went pending within five days – and sold for $1.013 million, or 27.4% over the list price.


As anyone involved in the residential real-estate market knows, bidding wars – and contract prices exceeding the list price – are the norm today in many markets around the nation.


Sheridan’s listing appraised at the contract price, and the deal went through without a hitch. But how do appraisers value a home in a market where prices are escalating rapidly – and where nearly two-thirds (64%) of listed homes faced bidding wars in March, according to Redfin, due to low mortgage rates and a severe shortage of homes for sale?


“The challenge is that the sales data you’re looking at is dated,” said Shawn Telford, chief appraiser at CoreLogic. “While the comparable sale might have closed three months prior to the appraisal, it went under contract before that, and market conditions five months ago were different than they are today. That’s where appraisers put on their thinking caps and dig in and do their research on how they might adjust the comparable sale they’ve selected to account for current market conditions.”


Indeed, time adjustments are a valuable tool that appraisers use to reflect changing prices in the local housing market. “They might look at the last three to six months of sales activity – or longer – in a defined market and try to extrapolate what the trend is,” Telford said. “If home prices increased month over month by 1%, they can use that pattern to support an upward adjustment to the comparable to accurately reflect what the subject property might be doing.”

Older Americans maintain record share of housing wealth Redfin says housing wealth held by those 70 and older has reached $13 trillion

By Didier Malagies • March 18, 2026
That Redfin data point—$13 trillion in housing wealth held by Americans 70+—is a big deal, and it ties into several powerful trends reshaping the housing and mortgage markets. What’s driving this record wealth? 1. Long-term home price appreciation Older homeowners bought decades ago at much lower prices and have benefited from massive appreciation, especially post-2020. 2. Low mortgage leverage Many in this age group either: Own their homes outright, or Have very small remaining balances So their equity = real wealth , not just paper gains. 3. Aging in place Instead of downsizing, many are staying put longer, allowing equity to continue compounding. Why this matters (big picture) 1. Supply constraint in housing Fewer older homeowners are selling, which: Keeps inventory tight Supports higher home prices This is one reason younger buyers are struggling to find affordable homes. 2. Wealth inequality across generations Younger generations: Face higher home prices Have less access to equity Meanwhile, older Americans control a disproportionate share of housing wealth. Implications for mortgage and lending 1. Rise of equity-based lending This trend directly fuels growth in: Reverse mortgages (HECMs) HELOCs Cash-out refinances That $13T is largely untapped liquidity . 2. “Living off equity” becomes more common With concerns around: Social Security stability Inflation More retirees are using housing wealth as: Income supplementation Emergency reserves 3. Intergenerational wealth transfer We’re seeing more: Parents helping kids with down payments Early inheritance strategies using home equity The hidden risk This isn’t risk-free: If home prices flatten or fall → equity shrinks Property taxes + insurance (especially in places like Florida) can pressure fixed-income retirees Liquidity is still “locked” unless accessed strategically Bottom line That $13 trillion figure isn’t just a stat—it represents a shift in where wealth lives in America : Housing is now the primary balance sheet asset for older Americans It’s becoming a retirement tool , not just a place to live And it’s quietly shaping everything from housing supply to lending innovation  Didier Malagies nmls212566 DDA Mortgage nmls324329
