Today's dispatch is light on rate and inventory data but carries two distinct analytical signals: a framework for reading why prices are elevated (not just that they are), and a new real-time tool for reading buyer intent before transactions close.

PRICE ANATOMY: Not All Appreciation Is Created Equal

Erdmann's latest is methodological, but the practical implication is sharp: the source of home price elevation tells you whether it will mean-revert or persist. His framework disaggregates appreciation into 3 buckets — supply-driven inflation (secular, structural, sticky), cyclical fluctuation (mean-reverting, proportional across price tiers), and credit-constraint suppression (pushes low-tier prices down without touching rents).

The diagnostic test is price behavior across tiers. Supply shortages produce asymmetric appreciation — cheap homes inflate faster relative to expensive ones because the shortage bites hardest at the bottom. Cyclical swings move prices proportionally across the whole market. Credit tightening compresses low-tier prices while leaving rents largely unaffected.

Erdmann's Mercatus paper applies this to the long arc from 2005 to now. His read: in 2005, roughly half of elevated prices were cyclical (Florida, Arizona running hot) and half were structural supply scarcity (NYC, LA). Today, it's almost entirely supply. The Covid-era 2022 bump he largely attributes to income stimulus and inflation noise — not a new demand regime.

The practical implication for anyone reading price-to-income ratios: a city that looks expensive because of supply constraints is a different animal than one running a cyclical fever. The former requires housing production to resolve; the latter corrects on its own. Erdmann's tracker tries to show which you're looking at.

DEMAND SIGNALS: What Buyers Are Actually Clicking On

Zillow's Olsen introduces the Zillow Buzz Index (ZBI), a real-time engagement metric built from views and saves across Zillow's 235 million monthly users. The signal: architectural character dramatically outperforms generic housing stock in capturing buyer attention.

Listings with exposed beams generate ~20% more daily engagement than the baseline. Victorian-style homes (+19.3%), exposed brick (+14.9%), arched details (+14.4%), and vintage features (+14.3%) follow closely. Tudor, midcentury, and A-frame styles each pull ~13-14% above baseline. Traditional forms — bungalows, Cape Cods, log homes — also outperform. Modern Farmhouse, Ranch, and split-level show negligible lift — the aesthetic that dominated new construction for a decade is now table stakes, not a differentiator.

Olsen frames engagement as more than attention: homes that exceed view/save thresholds go pending faster and are more likely to sell above list price. That makes the ZBI a leading indicator of both market velocity and pricing outcomes — useful for sellers setting strategy and builders making spec decisions.

The deeper read: in a market defined by affordability stress, buyers aren't just searching for square footage. They're filtering for homes that feel distinct and emotionally resonant. Character homes — which skew older and harder to replicate at scale — may be accruing a scarcity premium of their own.

Closing Synthesis

These two pieces point in complementary directions. Erdmann's framework explains why prices are where they are — and suggests that without supply expansion, the structural component of appreciation isn't going anywhere. Olsen's ZBI captures what moves buyers emotionally and behaviorally within that constrained environment. Together, they reinforce a market where inventory scarcity is both a price phenomenon and a preference-shaper: when buyers can't have volume, they reach for quality and character.

TL;DR - Price decomposition matters: Erdmann's framework shows today's elevated prices are almost entirely supply-driven — not cyclical — meaning they won't self-correct without new construction. - Character homes are outperforming: Zillow's new Buzz Index shows exposed beams, Victorian and Tudor architecture, and vintage features generate up to 20% more buyer engagement — and that engagement predicts faster sales and above-list prices. - Modern Farmhouse has peaked: Generic new-construction aesthetics show negligible engagement lift, signaling a buyer preference shift toward architectural distinctiveness.
