Has anyone ever used an All-in-One Loan instead of a fixed loan?

[Brian Goss]

The flexibility of an All-in-One loan has some appeal on a primary residence to be able to keep your equity working for you. The lender gives you a 1st lien HELOC with a 10-yr draw period, rate is variable , and it is attached to a checking account where the money sweeps nightly as needed to keep the account at $0. I was wondering if anyone has experience with this type of loan and what have been some of your learnings?

Thanks!
