Pay down rental mortgage or buy a second building

Part of: Leverage in Real Estate

mortgage leverage: you rarely get maximum monthly cash, maximum appreciation bet, and minimum landlord time at once—choose which you are optimizing.

The trade

Pick one primary goal: monthly cash now, long-run price gain, or least time on operations. Leverage in Real Estate maps the usual tradeoffs.

Constraints

If you will not handle tenant calls, include property management in the model or choose a different market. If you may need cash soon, do not rely on illiquid equity alone.

Two cards

Compare two bids: cheaper property with $40k immediate repairs vs. higher price with newer roof and HVAC. Use the same loan, reserve rate, and rent assumption for both before you choose.
