This document discusses factors contributing to the increased institutional allocation to real estate investments since the 1980s. Decreased interest rates, demand for stable income assets, opportunities for higher returns through value-add and opportunistic investments, and structural changes improving real estate investment accessibility have all played roles. While allocation has increased across institutions, pension funds allocate the most at around 20% due to objectives prioritizing income. Most literature predicts continued increases in real estate portfolio weightings by institutions to 15-30% by 2030, though at a slower pace as interest rates rise.
