Financing a tiny home just got easier. Here's why.

• A change in housing finance policy will make it easier for people to build ADUs.
• Fannie Mae and Freddie Mac will now consider projected income from ADU rentals when lending.
• It's a step towards building more ADUs, an expert said, but not everyone will benefit.

It just got easier for many homeowners to build a tiny home on their property. That's thanks to a major change in federal housing finance policy.
