Fran has a business, at least technically. Could she not claim that the location being purchased is a facility to grow that business?
She doesn't have much cash flow that the banks would recognize as stable income, which is why she couldn't get loans the last time she was in the moving situation. And as it turns out, the banks were entirely correct in that evaluation! Youtube/patron/solicited/gift money is not reliable long-term income!
For my personal property loan the banks did require an income statment from my accountant for my Pty Ltd business, and that
didn't break down income into Patreon income/donations.
So all the banks were looking for was consistentcy of business income, they didn't really care nor ask for where it came from.
I refuse to believe that it's not possible for Fran the restructure her business in some way that obfuscates the income source.
If the banks see the detail that the income comes from Patreon then you aren't doing it right.
Maybe the US is vastly different, but I doub it, remember it's the land of the 2008 subprime mortgage crisis that still perpetuates to this day in many ways.
If there is a will there is a way, but the problem is there is no will(ingness) to be flexible in location for starters.
