Jumbo Loans: Complete Guide to High-Balance Mortgages

When you're buying a luxury home or property in an expensive market, you may need financing that exceeds conventional loan limits. That's where jumbo loans come in. These specialized mortgages help qualified borrowers purchase high-value properties with competitive terms. Here's everything you need to know about jumbo loans in 2024.

What is a Jumbo Loan?

A jumbo loan, also called a non-conforming loan, is a mortgage that exceeds the conforming loan limits set by the Federal Housing Finance Agency (FHFA). Because these loans are too large to be purchased by Fannie Mae or Freddie Mac, they're held by lenders or sold to private investors, which typically means stricter qualification requirements.
