Don't disqualify yourself without talking to an expert. 

Consider doing this personally or using an LLC.

Hey Mike, always nice to see attorneys who get into the investment game themselves, and great to hear about what you're doing.

However, after talking to some loan professionals, it seems that there are always origination fees, appraisal fees etc.My question is, what fees should I expect to pay when opening up my first HELOC.  

If they do, your best bet is a local community bank that funds these types of properties.Another option is a private lender but that money will be pretty expensive, as mentioned 10%  + 

If you're willing and able, I do recommend the "house hacking" strategy which is just a fancy name for buying a rental property and living in one of the units, because you'll get very favorable financing - an owner-occupied fixed-rate 30-year mortgage.I'd also say, analyze that property as if you won't live there and it's a pure rental, and make sure the property is still cash flow positive if there's a tenant in your unit because then you'll know if it's actually a good investment.And when you analyze it, include payment of a property manager in your #s because if you don't, and doing so would make it go cash flow negative, then you've just bought yourself a job because you literally can't step away from managing it without losing money.

You'll do well if you're this disciplined at 18!

The short answer is yes, but it's much harder.
