@leeloo , thanks for the IRS link, it clearly said here: The two most common methods for dividing an expense are (1) the number of rooms in your home. since there only 2 bedrooms, the 3rd one is converted for working due to WFH actually, so that is why i say 50% or 33% based on this # of room method. but if use square foot method, it will only be 10%, so clearly # room method or # people method gives more deduction to minimize rental incomes, so that is why i am asking can i use this method for expense deduction while using square foot method for depreciation to prevent higher tax bracket issue later after recapture.
