The requirement of a 20% downpayment for a home loan is no longer the standard, and buyers can now put down anywhere from 5-20%, depending on their situation. Factors such as credit score, income, and age all affect the amount of the downpayment, with conventional loans requiring a minimum of 3%. Additionally, there are favorable first-time homebuyer programs with even lower downpayment requirements, allowing more people to own their own home.
