Interest rates are at historic lows, but they're going up. I would use this opportunity to re-fi at the very least to get you into a lower interest rate while you still can. If you're thinking you're going to want to pick up an additional property in the next year or so and don't otherwise have the cash on hand for a down payment or to pay cash for a deal, it could be a good time to do a cash out re-fi so you have that cash available when you need it. Given the market uncertainty, though, I would be wary of increasing my monthly mortgage too much (which can happen with a cash out re-fi because you're essentially borrowing more) since it sounds like your renters are just barely covering the existing mortgage. You may not be able to count on rents going up to keep pace with your new mortgage payment. As for a HELOC, someone mentioned that you only pay on it if you use it and that's true. It's like having $ you can call on if you need it and the time to establish it is when the value of your property is still high and you have equity. If values drop, so does your equity so the amount you can use can diminish. Also, if you're thinking about getting it but not using it unless you want to or need to, double check whether there's a period of inactivity after which the lender will close a HELOC loan.
