Sunk Cost in Real Estate

Sunk cost in real estate is the trap of pouring more money into a delayed or troubled property project because of the large amount already committed.

Buyers of stalled under-construction projects often keep paying instalments or accept poor terms because they 'can't lose' what they have already invested — even when the rational move might be to exit, seek RERA redress, or refuse further payment. The money already paid is gone regardless of what you do next.

The forward-looking question is whether additional rupees are best deployed here or elsewhere, given the project's real prospects. Recognising the sunk cost fallacy helps buyers make decisions about troubled property based on future value and legal remedies, not on the size of past commitments.
