Adding the burn arithmetic to what the guide reply laid out, because it's the line that decides whether tally's deal works.
Minimum compliant staffing on a licensed six-bed is roughly one caregiver on days, one on evenings, and overnight coverage that may have to be awake depending on the state. Call it 225 hours a week at $19, so about $18,500 a month once you include payroll taxes and relief coverage. You cannot run half of that because you have two residents. Licensing minimums are per-shift, not per-resident, at that size.
Fill at one resident a month at a $4,800 blended rate and cumulative operating deficit through month six lands somewhere around $70k to $100k depending on how fast you get the first two admits. That's the working capital number, and it's larger than the sprinkler retrofit and the license process combined.
On insurance, general plus professional liability for a six-bed private-pay home is often in the $4,000 to $9,000 a year range, and it moves hard with claims history and state. Workers comp for caregiver class codes runs several dollars per $100 of payroll in many states, so on $220k of annual wages that's a real number, and it's underestimated in nearly every spreadsheet I see. Get bound quotes before you close, since some carriers won't write a first-time operator at all.
One more thing to check before you spend on plans: ask the fire marshal in writing which occupancy classification six ambulatory residents triggers versus six residents where any are non-ambulatory. In several states the answer changes the sprinkler and egress scope entirely, and that's the difference between your $18k bid and your $31k bid.
