ADU in SF Bay Area - loan question / advice

[Andy C.]

HI Bigger Pockets,

I'm looking to add an attached or detached ADU(granny unit) on my existing home here in San Mateo in SF Bay Area.

The rough estimated costs for contractor, labor and materials is between 280-320k. (about 6-800 sqft)

Is anyone on here familiar with or aware of any programs or products out there that would allow for financing this? And or has anyone been successful with this sort of a project?

Thanks in advance for any tips!

Andy

Ps. Last we talked we had a few blemishes on our credit report hopefully that does it make an impact but I want to see if there are any other products or programs out there that would not affect a loan like this.
