In an emergency situation you could always access the HELOC at 8%-13%.This emergency situation should be considered before the funds are accessed with either method, can you afford to have no savings AND be paying 8%-13%.

This is not to say this is the only successful method of real estate investing, but as I'm sure you're well aware, with current interest rates and overall market conditions, sourcing and acquiring LTR deals is difficult unless you're going off-market.

can you share your methods and tools?
