A Reverse Mortgage or HECM loan is an Agency backed mortgage that allows you to access a portion of your equity with no payment required, the interest you're not paying gets added to the loan. This is called reverse amortizing b/c rather than paying down your loan the loan increases over time. It's designed for individuals over 62 that want to stay in their home but otherwise can't afford to.
We do offer bank statement HELOCs for business owners who don't show income on paper but can show revenue coming in(bank statements), doesn't sound like that applies here.
Freddie Mac allows for assets to be counted as income, 70% of total divided by 240. So for every Million you get $4167/mn to use as income. But again, 62 and older. - Only allows Rate/Term but we could add a HELOC on top of it to access cash in this instance up to 95% CLTV.
Long story short, there are ways but you'd have to get creative and be over 62.
