Are asset-based mortgages a thing?

[Sherry W.]

I am moving to a new state, and want to keep my current property that I live in as a rental. I have a mortgage of roughly 100K left. I want to buy a new home in the new state, however, I am early retired with no W-2's. I do have significant investments though, 1.5 million in stocks, (available and accessible) and 1.1 mil in an IRA (not accessible). I could pay cash for the new property, but I'd rather keep that money invested, and get a mortgage at the current low rates. FICO of 757. Is this possible?
