I would highly recommend doing a renovation loan like the 203k or homestyle - you are able to leverage SO MUCH CASH for such a low down payment. 

So I would highly recommend leveraging your money and don’t pay off your primary.

This convenience and leverage can justify the higher cost of these loans.Personally, I prefer using a HELOC because I only have to apply once and can then tackle one or two projects at a time.

Honestly, over leveraging is a really bad idea at this time (just my 2 cents). 

The real property investment can be repositioned if it proves disappointing in its original form; it can be refinanced or recapitalized if it has too much or too e pensive debt; inflation over time bales out many bad purchases, and finally the investors knowledge, experience and abilities can be leveraged to turn around a cash flow negative property.I’ll provide an exampleThree years ago we purchased a note from a bank secured by two auto repair facilities with a large amount of excess land.  

Hey @Cassidy Burns,Great deal—quick turnaround and leveraging 100% LTC financing is impressive!

@Brett Jurgens To leverage your Denver rental's equity, consider a HELOC or cash-out refinance to access funds while keeping the property and rental income.

Real estate purchase using reasonable leverage, at todays interest rates, will build up equity through amortization.  

As you and @Wayne Brooks both pointed out, could even offer some leverage to myself as the buyer.

My goal is 25 doors in 5 years, my struggle right now is deciding to either go back to work and save up money to continue or come up with a way to leverage financing to stay afloat myself and stick with it, waking up everyday 100% dedicated to my real estate.
