Cash-out refi as an engine, not an exit
Refinance on a schedule and it compounds. Do it opportunistically and it is just borrowing against optimism.
The pitch for a cash-out refinance is always the same: pull your capital back out, buy the next one, repeat. What nobody says out loud is that you are re-levering an asset you already understand to buy one you don't, and you are doing it at whatever rate the market feels like offering that quarter.
Done on a schedule, it is the most powerful tool on this roadmap. Done opportunistically, it is how people with twelve doors end up with negative cash flow and a great story.
The rule I'd give a version of myself at Year 6
Refinance when the debt service coverage on the post-refi loan still clears 1.30 at 80% occupancy — not at your current occupancy, and not at the rent you plan to charge after renovations. If it doesn't clear, you are not scaling. You are borrowing against optimism.
Every refinance should shorten the distance to Year 20, not just extend the runway on Year 7.
