The most common downpayment depends on the borrower. Most first-time homebuyers (FTHB) will opt for the minimum downpayment option available, which is 5% on the first $500,000 and 10% on the remaining amount between $500,000 and $999,999. For borrowers in large cities where home prices are well above $1 million, a 20% downpayment or more would be required.
