I've been told by plenty of people just to wait until I'm a few years older and I have more savings, but I am really wanting to get started as soon as humanly possible.Ideally, I am looking at private financing to purchase the property and then eventually refinance the property since I know the interest rates will be higher and I would like to pull some cash out to possibly fund another deal. 

Why would you pay off the rest of the loan instead of doing a cash out refinance?

We live in one unit and working on renovating to increase our appraisal for a cash out refinance to fund the next deal!

In the context of BRRRR refinance means pull out all or most or some of money you invested into the deal so you can go onto the next step, repeat.

It took talking to several mortgage brokers to even find someone who could help me get refinances.

We want to renovate the units ourselves to get a cash out refinance. 

Also, make sure you make your payments on time and make them trackable (Venmo or check are fine, but NO CASH) so you don't blow your refinance; especially if the renovation or stabilization of the property goes long and you run into a situation where there's a balloon or you're in default. 

I personally would spend an afternoon and reach out to different local lenders (banks and credit unions) and see what they will offer for a HELOC or possibly refinance the existing loan if your rate is high.

What advice can you give me on funding through a cash out refinance versus a heloc.

I have a 36 month period of time that I have to wait to refinance the property or pay a penalty.
