Three out of four young adults who recently bought their first home needed their parents’ help to afford the down payment, closing costs or other expenses, a new survey finds. Interest in homeownership is picking up, especially among first-time buyers, and mortgage lender loanDepot LLC commissioned a survey to find out how today’s millennials — 97% of whom will take out a mortgage to buy their homes — plan to pay for their investment. It seems the “bank of mom and dad” is a fallback most count on, with 75% of young adults who recently bought a home saying their parents helped them out.
