Should interest rate rise significantly, we may find a completely different experience.As per your second question, while many may disagree with me here, I will tell you that based on my 40 years experience in real estate, tax savings as a selling tool to convince a seller to owner finance is the most over hyped and least successful argument anyone present to a seller.Years ago, when interest rates where high double digits and few people qualified for a mortgage, sellers had little choice but to owner finance or accept a very low price from someone who could buy for all cash.
