A "piggyback loan" will allow someone with a low down payment, or even no down payment, to purchase a home without PMI. This is actually a name for getting two separate loans. The first loan will be for of 80% of the property’s value, so there will be no PMI requirement.
Home buyers who don't want to make a 20% down payment or pay for PMI. To get a conventional loan without PMI, you'll need a 20% down.
