I was told I cannot do a conventional CASH OUT refinance once I lease it to an operator of RAL since lenders do not lend if you run a business in your house.

Home Equity Lines of Credit (HELOCs) or cash-out refinances can access built-up equity without selling the properties.

I inherited my father's home and am entertaining someone who has cash offer for the house.
