WHEN ADNAN SABIC started searching for a house in 2023, he was shocked. The lodge govt, whose spouse had simply given delivery to twins, couldn’t consider how mortgage charges had rocketed. Then he discovered a four-bedroom home listed for $775,000 with a pleasant promoting level. Somewhat than borrow at 6% and pay $4,500 a month, Mr Sabic might “assume” the vendor’s mortgage, at 2.6%, and pay simply $3,100.
