I dont understand your question? People whose home has a mortgage can deduct the interest....maybe
People who own mortgaged property used for business (rental or other) can claim the interest as an expense
But yes, you could set up a corporation or a nonprofit foundation to own your home, Rahm Emmanuel did/does this as was determined from property tax records, surely many many sharp lawyers could help set up tax-advantaged shelters for your family home and income. Tax avoidance is how many of the real “rich” became rich and will stay rich
I just read that Ted Kennedy’s widow is “donating” his mansion on Cape Cod to become a nonprofit “retreat” - with lots of room for family vacations...err retreats....at any time, of course
In case thay drop home owner interest deductions.
