It had been more than a decade since U.S. home sellers netted a greater profit than they did in 2018, according to ATTOM Data Solutions' Year-End U.S. Home Sales Report. The average home sale last year gained a massive $61,000 since purchase, good for a 32.6% return on investment; both of those amounts were the largest since 2006. That year, homes sold for a net gain of $68,000, or 43.3% ROI, on average. By comparison, 2017's home sellers saw profits of only $50,000 (27% ROI).
