Put in the house, the community's fee sheet and Mom's money. See how many months of care each choice pays for, side by side.
Rough numbers are fine. Everything updates as you type.
Use the community's fee sheet for the monthly fee, including the care level charge.
A cash buyer who takes it as-is usually pays 20 to 50 percent below what the house would be worth fixed up, depending on condition. No repairs, no commission, and it usually closes in weeks instead of months.
These are questions to ask, not advice. Each one depends on Mom's state and her paperwork.
