Surviving the Refinance Wall: Lessons From an $8B Portfolio with Sarah Esler, Managing Director of Mortgage Investments at AIMCo

AIMCO’s mortgage investment platform, backed by Alberta’s pension funds, oversees roughly $8 billion in private mortgage assets. About 55% of the book sits in Canada, with the remaining exposure spread across the United States and Western Europe. The fund’s structure reflects a client‑driven allocation model, where each pension, endowment or insurance sponsor earmarks roughly three to five percent of its portfolio for private mortgages. First‑mortgage term loans dominate, while specialty bridge and construction financing represent a modest slice of the overall mix.

The current credit environment is exceptionally competitive. Short‑term capital is abundant, compressing spreads to historic lows; five‑year loans are priced near 4.25% and the gap between five‑ and ten‑year yields is unusually wide. This steep yield curve enables AIMCO to secure higher returns on longer‑dated deals while maintaining disciplined leverage ratios—typically 60‑70% loan‑to‑value—and a preference for non‑recourse structures. Canadian borrowers lean heavily toward fixed‑rate financing, contrasting with the higher‑leverage, floating‑rate appetite seen in U.S. and European markets, a divergence rooted in differing banking systems and institutional investment horizons.

Risk management remains a cornerstone of AIMCO’s strategy. A two‑tier watch‑list system flags early‑stage stress signals, focusing on cash‑flow adequacy and cap‑rate trends rather than merely missed payments. Construction and floating‑rate loans have posed the most volatility, but fixed‑rate, income‑producing assets have stayed resilient. With confidence growing that the market is at a low‑cycle inflection point, AIMCO is eyeing further expansion in high‑growth Canadian regions such as British Columbia and Quebec, betting on renewed equity conviction to drive the next wave of mortgage activity.
