Buyers assume new-build flats are likely to rise in value over time
An analysis of 10,000 sales in the period 2015 to 2025 showed that profit outcomes diverged markedly
What this means in real terms
Across all resales, profit outcomes ranged from -52% to 50% – most buyers lost money, some large chunks of their capital, but some made substantial gains
What you get
Same flat resale outcomes
Profit after Stamp Duty and adjusted for inflation
The reasons why profit outcomes diverged
Why profit drivers remained consistent over time and in different market conditions
Clear tables you can use
This is not a get-quick-rich guide to property investment but rather a clear, evidence-based examination of a market where expectations and reality often diverge
