I have also found on HUD where they support these types of loans mentioned in the article from rocket mortgage. Where’s the banks that do this and are the qualifications similar to single family 1-4 unit FHA?

From rocket mortgage copy and pasted: What Is An FHA Multifamily Loan?

A Federal Housing Administration (FHA) multifamily loan allows borrowers and real estate investors to buy a multifamily home, which is defined by the FHA and other mortgage investors as a property that has 5 units or more. Homes with up to 4 units are considered single-family housing, so those properties wouldn’t qualify for this type of loan.

I’m aware of the well known info that FHA only works for properties with up to 4 units. But I found this article along with HUD applications for this specific loan without much info as to qualifications such as down payment or any additional specifics other than the physical state of repair and maintenance on the property which would be deemed appropriate or not by an FHA appraiser.
