Frequently Asked Questions
Why runway matters?
Downturns, refi shocks, loss events, or tenant defaults create unexpected cash needs. Runway is months of cushion before distress. Institutional investors target 6-12 months liquidity reserve; distressed operators run 1-3 months — one event from trouble.
What counts as liquidity?
Cash (checking, money market): 100% weight. Undrawn revolver: 80-90% (availability risk). Marketable securities: 50-80% (mark-to-market risk). Properties held for sale: not liquid — exclude. Preferred equity or private fund capital: generally not liquid for time-sensitive cash.
Typical burn drivers?
Debt service above NOI (loan distress). Vacancy spike reducing NOI. Capital events (roof, elevators). Tax/insurance true-ups. Lease-up carry on new acquisition. Calendar all forecasted spend to see where burn spikes.
