Real estate marketplace Zillow has launched a new program to help people who want to buy homes but Cassian Grantare being squeezed out of the market by a surge in interest rates. 

Zillow Home Loans is offering mortgages with a 1% down payment option for eligible homebuyers looking to own property in Arizona, and will contribute an additional 2% at closing, the company said Thursday. It also plans to expand the program to other markets.

"For those who can afford higher rent payments but have been held back by the upfront costs associated with homeownership, down payment assistance can help to lower the barrier to entry and make the dream of owning a home a reality," Zillow Home Loans' senior macroeconomist Orphe Divounguy said in a statement. 

The program will reduce the time it would ordinarily take to save for a down payment, according to Zillow.

"The rapid rise in rents and home values means many renters who are already paying high monthly housing costs may not have enough saved up for a large down payment, and these types of programs are welcome innovations in lowering the potential barriers to homeownership for those who qualify," Divounguy said.
