The referral network question is the one that actually kept me up. My operator on the triplex conversion I did in Wrocław, different country and not apples to apples on regs but the ramp math translates, came in with what she described as "solid hospital contacts." What that turned out to mean was she knew two social workers by first name from a previous job, neither of whom were still in discharge planning roles. We were at three residents at month four. Month seven we finally cracked five. Full at nine months. That gap cost me about 28,000 PLN in carry beyond what I had modeled, which at the time was around 6,500 USD, and that was with lower baseline expenses than a US operation.
The thing I would push back on with your 90-day assumption is not the number itself, it is that you are starting with four bodies already in the home, which is genuinely different from a cold start, and I think people are not weighting that enough. The two open beds are not equivalent to six empty beds. You have proof of concept in the building, existing residents generating word of mouth in the family network, and a seller who presumably has some goodwill with whoever placed those four. I would be asking hard whether the seller will make one warm introduction to the discharge coordinators at those two hospitals as a condition of close, or at least as a handshake ask. That is worth more than any organic ramp your operator builds from scratch in an unfamiliar market. If the seller says no or hedges, that tells you something about whether those referral relationships are actually portable or whether those four residents came in through some other channel entirely.
