Self manage versus ten percent to a manager

Part of: Cash Flow

rental cash flow: 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. Cash Flow 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.
