I’m Selling My Law Practice and Retiring. Do I Pay Off the $2 Million Loan on My Office Building — or Keep the Mortgage?

Why It Matters

The decision illustrates how high‑net‑worth retirees balance debt, liquidity, and tax considerations to protect income streams and mitigate market‑timing risk during the distribution phase of wealth management.

Key Takeaways

• $2M mortgage yields $300K annual rent versus 4% portfolio return
• Paying off loan ties up equity in a single commercial property
• Interest rate determines whether debt service costs less than market returns
• Using practice sale proceeds avoids extra capital‑gains tax on investments
• Maintaining liquidity protects against early‑retirement market downturns

Pulse Analysis

Retiring attorneys often face a binary choice: eliminate debt or preserve capital. In this case, the 64‑year‑old lawyer owns a $3.5 million office building with a $2 million mortgage, generating $26,000 a month in rent. With $2.5 million in investable assets, $4.5 million in retirement accounts, and an expected $2.5 million proceeds from selling the practice, the couple’s net worth exceeds $12 million. The decision hinges on whether the predictable rental cash flow outweighs the concentration risk of having a single tenant and a large real‑estate exposure.

The mortgage’s interest rate is the decisive metric. At a low rate of 2.5 %, the cost of servicing the debt is well below the historical 7‑8 % equity return of a diversified portfolio, making it sensible to keep the loan and let the market work. Conversely, a 6 % rate erodes potential gains, favoring an early payoff. Tax efficiency also matters: using the $2.5 million practice sale to retire the loan avoids a separate capital‑gains event, while pulling cash from taxable accounts would trigger additional taxes.

Given the likely moderate rate—between 4 % and 5 %—a hybrid approach often provides the best balance. Allocate a portion of the practice‑sale proceeds to reduce the mortgage, preserving some equity for liquidity while boosting cash flow to roughly $200,000 annually. This maintains a safety cushion against early‑retirement market volatility and the risk of vacancy after the ten‑year triple‑net lease expires. Ultimately, the couple should prioritize tax‑neutral debt reduction, retain enough liquid assets for the sequence‑of‑returns risk, and reassess the loan strategy if rates shift.
