I'm going to include margin loan in there, since for me it takes the place of a HELOC. In fact I sought out a HELOC before retiring, and discovered that in NYC you pay a 1.8% on the *capacity* of the loan at close, even if you never use it. I therefore switched my Vanguard brokerage account from cash to margin, now I have a 7-figure borrowing capacity. I'll be using a portion of it soon (for a very short period of time), as I'm buying a house in the burbs and will close on it before I sell my NY condo. So the margin loan will serve as a bridge loan for the interim.
