low - USPS operates as an essential government service with constitutionally mandated mail delivery, making rental income highly recession-resistant. Mail volumes may decline during economic weakness, but USPS maintains physical infrastructure regardless of economic conditions. The company's growth through acquisitions may slow if sellers delay transactions during uncertainty, but existing cash flows remain stable.

Rising rates negatively impact PSTL through multiple channels: (1) Higher borrowing costs compress acquisition spreads and returns, reducing accretive growth opportunities; (2) REIT valuations compress as dividend yields become less attractive relative to risk-free rates; (3) Equity cost of capital increases, limiting ATM program effectiveness for acquisition funding. However, fixed-rate debt (estimated 60-70% of total) provides partial insulation. The company's 7-9% acquisition cap rates provide cushion versus current financing costs, but sustained rate increases above 6-7% would materially pressure economics.

dividend - Investors seek stable, government-backed income with 5-6% dividend yields and modest growth. Appeals to income-focused portfolios wanting defensive real estate exposure with lower volatility than traditional office REITs. Recent 46% one-year return suggests momentum investors have entered, but core holder base values predictable cash flows and USPS credit quality over growth.
