I'm currently a college student, so I don't make a lot of money.

Grad students are calmer, quieter, more focused, usually a bit more money.

Cash flow is realistic, but quite frankly you make your money here in appreciation.

From a leaky roof to a backyard jungle, it was a crash course in problem-solving and patience.I bought it for $145,000, powered through the chaos with a hard money loan, and sold it for $180,000.

Some of The pros  there is that I see my money first, and then I pay out my 1099 employee. 

This might not reduce your taxes, but it's a better use/return for your money than paying down a 4% or 5% mortgage. 

I didn't understand why I could not get my money out of a free and clear asset. 

If you don't need money you pay down the HELOC. 

It can save you money, strengthen your relationship with your property manager, and help ensure compliance with lease agreements.

With that money - I am using it to invest using the BRRRR method.
