The DSCR (debt service coverage ratio, the ratio of your monthly rent to your monthly mortgage payment) is what keeps the deal alive, so clearing 1.25 is genuinely meaningful. But the cash-out amount matters for a different reason: it determines how fast you can run the next cycle.
The way BRRRR is supposed to work, you pull most of your capital back out at the refinance step and redeploy it into the next acquisition. If you leave $25,000 in every deal, and you want to buy four properties, you need $100,000 more than if you had recycled that capital. The deal works. The pace slows.
The strategy guide for this version of BRRRR names this directly: the current rate environment is leaving capital partially stranded in each deal, and that is the defining friction right now, not a sign that you are doing something wrong.
On your Conroe situation, 68% LTV before the appraisal is actually the more important variable. If comps in that market drifted during the eight months of construction, the appraised value could move either direction, which changes your LTV and therefore how much you can pull out. I would not frame the leftover capital as fine or not fine until you see that number. A licensed appraiser who knows new construction comps in that submarket is the right person to pressure-test the value assumption before you set expectations.
As for your actual question, there is no universal threshold where stranded equity stops mattering. It depends on how many deals you plan to run, how much capital you have waiting, and how long you are comfortable waiting between acquisitions.
How many more acquisitions are you planning to run in the next two years? That would help frame whether the recycling gap is a pacing problem or something worth restructuring around.
