[Verse 1]
Property values scattered across the land
How do we track what's changing by hand?
Appraisal-based indices start the game
Sample transactions, but who's to blame?
When markets move slow, data gets stale
Six months behind, the numbers can fail
[Chorus]
REIT returns, repeat sales, hedonic too
Three main methods, each one's got a view
But watch for lags, smoothing makes it clean
Real estate indices aren't what they seem
Transaction costs and liquidity's lean
REIT returns, repeat sales, hedonic scene
[Verse 2]
Repeat sales method tracks the same address
Sold twice or more, removes the guess
Controls for quality, that's the hook
But sample bias skews how markets look
High-turnover properties dominate
While stable buildings never participate
[Chorus]
REIT returns, repeat sales, hedonic too
Three main methods, each one's got a view
But watch for lags, smoothing makes it clean
Real estate indices aren't what they seem
Transaction costs and liquidity's lean
REIT returns, repeat sales, hedonic scene
[Bridge]
Hedonic pricing breaks down every trait
Square footage, bathrooms, calculate the rate
But characteristics missed distort the price
And model specification needs precise
REIT indices trade daily on exchange
But property exposure gets rearranged
[Verse 3]
Appraisal smoothing hides volatility
Professional opinions lack objectivity
Temporal aggregation blurs the trends
While geographic coverage never ends
The heterogeneity challenge grows
Each property's unique, as everyone knows
[Chorus]
REIT returns, repeat sales, hedonic too
Three main methods, each one's got a view
But watch for lags, smoothing makes it clean
Real estate indices aren't what they seem
Transaction costs and liquidity's lean
REIT returns, repeat sales, hedonic scene
[Outro]
From Case-Shiller to commercial trust
Index construction faces headwinds robust
No perfect measure for this asset class
But understanding flaws helps knowledge pass
