I am struggling financially and I need to pay off some large gambling debts & other unsecured loans. Can I get a Reverse Mortgage to do that?

No, I would say not. Lenders are very wary & cautious about lending to clients who are poor financial managers. If you have large gambling debts, and lots of unsecured loans, it can be a serious red flag indicator to a lender. It would not be financially responsible of them to lend you any more money, so it would be best not to apply for a Reverse Mortgage as you will most likely be declined.
