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. 

That's the simple, proven method that leads to success.

@Alessa LeSarThe BRRRR method is a way to grow a a limited-capital real estate portfolio by buying homes, fixing them up, renting them out, refinancing, and doing it all over again.

can you share your methods and tools?

Per my request they sent me a YouTube video (see above) where it’s placing a bracket to hold the filter and disconnecting the cold water faucet hose from the shutoff valve, then installing a water supply line adapter to the cold water faucet hose.

I feel my current method is working me too damn hard but it is working and moving me in a steady upward direction...    

Although it can feel 'old-school' sometimes local buyers prefer traditional marketing methods.
