Primary residence loans that are not the usual product backed by the government are called "non qualified mortgages" aka non-qm.non-qm providers can be more creative like using bank statements instead of pay stubs, but I can't think of anyone that does not do income verification.

Has anyone used these products?

Going into an offer thinking "I don't know why she would want to" isn't going to be productive.

If you know someone who offers that product, please raise your hand.
