Investors & landlords

What impact would not having any profit from the sale have? The house is a long-term asset in a community property state, and my husband died a year ago. Because of the 100% step-up in cost basis I should receive for the house due to his death, plus the cost of improvements we made to the house, I shouldn’t owe any capital gains taxes. Would offering owner financing interfere with getting the step-up in basis?
