This would be a group home for medically fragile children that foster care agencies could utilize. There are well run ones and abysmal ones. One of our children came out of a home like this. The place sucked and ran into all sorts of issues. There were 6 kids, 4 were in foster care, 2 were parental placements. Their primary issue was that the state (Medicaid) was paying for PDN nurses for two of the kids but the home used those nurses to care for all the kids and oversee the staff CNAs that worked there.
If you do your research, run it well, don't utilize fraud to save money and don't become greedy, it could be a great thing. It's a lot of money to modify a home (doorways, ramps, driveways, bathroom, showers, kitchen, generators). Also consider that you will need lots of space for storage for medical supplies at the bedside and someplace else for the overflow/back-up. You also need a place for potentially six wheelchairs, six standers, six corner chairs/floor sitters, six seating devices, six shower chairs, etc. Pedi cribs/beds can run from $5K each to $30K each.
Start googling and see what's out there. You'll also see what you do and don't like out there.
Please let us know how you progress!
