What it would mean
If this plays out, it is a risk-on shock. Institutional build-to-rent communities expand to meet priced-out renter demand, giving builders a steady offtake channel that supports starts even with weak resale; BTR-linked builders and operators re-rate. The trigger decomposes into signed root‑shocks — Consumer spending ▲ · Mortgage rates ▼ · Risk appetite ▲ — which propagate through our causal graph to the markets below.
