Development Cycle and Overbuilding
Real estate cycles look mysterious until you understand the construction lag. A developer decides to build today, but the building does not deliver for 2-4 years. Every developer reads the same signals at the same time, so they all break ground together — and the wave of finished product lands together too. The result is a roughly 7-year boom-bust cycle that has repeated across every cycle in modern US real estate history. For an investor, knowing which phase a market is in matters more than picking individual properties.
The construction lag is the engine of the cycle. Permits, financing, design, and construction together take 2-4 years for office and multifamily, longer for large mixed-use projects. The decision to build rests on demand visible today; the supply lands in a market that may have shifted dramatically by delivery.

§ 03
The developers mistake is acting on stale signals. Rising rents in 2025 are the demand signal that prompts the build decision; the same rising rents are visible to every other developer. By the time the cohort of new buildings delivers in 2028, the demand picture may look completely different and the supply wave hits a softening market.
§ 04
The pro signal is not counting cranes — it is tracking absorption rates (how much space is being leased) against deliveries (how much is finishing construction). When deliveries outpace absorption by a meaningful multiple, a rent and price reset is essentially priced into the supply math. Sun Belt office, certain Phoenix-area multifamily submarkets, and several Las Vegas retail corridors have repeatedly demonstrated this dynamic across the past three cycles.
§ 05
Pull the latest market report for a city you know well (CBRE, JLL, and Newmark all publish free quarterly reports). Compare the trailing-12-month absorption figure to the scheduled deliveries figure for the next 12 months. If deliveries are more than roughly 2x absorption, the market is heading into hypersupply within the next 12-18 months.
§ 06
A REIT focused on a single Sun Belt office market discloses that its market has scheduled 5 million sf of office deliveries over the next 18 months against trailing absorption of around 1.5 million sf annually. The REIT trades at a 25 percent discount to NAV. What should an investor reading this make of the situation?

Sit with the ideas.
A growing Sun Belt metro shows office absorption running near 2 million square feet annually for the past three years. Cranes are visible across the skyline, and a regional REIT discloses that 6 million square feet of new office is scheduled to deliver across the next 18 months. What does an investor reading these numbers reasonably conclude about the next phase of this market?
