The framework treats public and private real-estate valuations as differently biased signals during a dislocation. Listed markets reprice daily and rapidly incorporate changes in rates, sentiment, and broad stock-market flows, but they may overshoot fundamental asset values. Private valuations depend heavily on appraisals and comparable transactions, so they adjust slowly when few properties trade. Investors first normalize for asset quality, leverage, and sector exposure, then use public discounts to net asset value as the lower or faster-moving signal and current private appraisals as the slower signal. Fair value is bracketed between them and refined as forced sales and other transactions create credible evidence. This avoids blindly accepting either market's temporary distortion.

Core principles
- 01Public markets incorporate information quickly but can overshoot
- 02Private appraisals update slowly and can understate market change
- 03Low transaction volume weakens comparable-sales evidence
- 04Fair value may lie between public prices and private appraisals
How to run it
- 1
Define comparable exposures
Match public and private assets by sector, geography, quality, occupancy, and leverage before comparing valuations.
Pro tip Use the underlying properties rather than broad labels such as office or residential.
Watch out Differences in debt and asset quality can make headline discounts misleading.
- 2
Read the public signal
Measure listed-market prices against net asset value and examine how quickly the securities reacted to changed rates and sentiment.
Pro tip Look for indiscriminate selling across both strong and weak assets.
Watch out Stock prices reflect flows and sentiment beyond property fundamentals.
- 3
Audit the private signal
Determine when appraisals were updated and which comparable transactions support their assumptions.
Pro tip Focus on the freshness and relevance of transaction evidence.
Watch out Quarterly appraisal marks can remain stale when market activity collapses.
- 4
Adjust for current capital costs
Recalculate yields, financing expenses, and required returns using present conditions rather than historical debt costs.
Pro tip Stress-test the valuation across plausible refinancing scenarios.
Watch out Healthy property income does not eliminate capital-market risk.
- 5
Create a valuation bracket
Treat oversold public pricing as one boundary and slowly adjusting private values as the other. Place the working estimate between them based on evidence quality.
Pro tip Use a range rather than false precision while price discovery is incomplete.
Watch out The midpoint is not automatically correct if one signal has materially better evidence.
- 6
Update with completed transactions
Narrow the range as sales close and establish credible market-clearing yields and prices.
Pro tip Weight forced transactions carefully but do not ignore them when they become the only available evidence.
Watch out Indicative bids do not carry the same evidentiary weight as completed sales.
In the wild
Marcus notes that listed office vehicles owning modern, transit-accessible, ESG-qualified assets suffered roughly the same market hit as vehicles holding Class B offices. That indiscriminate decline suggested the public market had overreacted relative to differences in underlying quality.
→ The gap identified a potential opportunity in higher-quality listed real estate trading below net asset value.
Private appraisers need comparable transactions to substantiate lower values and higher yields. When liquidity disappears and transactions take two or three times longer, quarterly appraisals adjust gradually even though financing conditions have already changed.
→ Investors avoid mistaking slowly updated appraisal values for current market-clearing prices.
Common mistakes
Taking public prices literally
Daily markets can overreact to sentiment, index flows, and macroeconomic news unrelated to the exact quality of the underlying properties.
Trusting stale appraisals
An appraisal supported by old comparables may understate the effect of higher rates and weaker liquidity.
Comparing unlike portfolios
A discount is not meaningful until differences in leverage, property quality, geography, and sector exposure are normalized.
Is it for you?
Best for
It is best for investors comparing REIT pricing with private commercial-property valuations during market dislocations.
Not ideal for
It is not ideal when public and private assets are not operationally comparable or when reliable current transactions are abundant.
From the transcript
“the public markets have overreacted and overshot, and the private markets have underreacted and somewhere in the middle is the right value.”
“in the private markets it's appraisal based, and so it takes a long time for appraisals to really reflect market value.”
