I am 22 years old and just started working full time but my long term goal is to be financially free.For the short term I will continue to listen and read more books.

Plus the entity structure you choose will tailor to your goals and strategies. 

But if it's still possible, staying with a smaller mortgage payment while sinking the difference and any extra into student loans would probably accelerate your goals.

My goal is to convert it and live there while renting the other unit.

My goal is to have at least 10 properties within the next 4 and 1/2 years.

I am aiming for a 2 month timeline, for my first flip and working a FT job that might be a bit ambitious, but that's what goals are for. 

My goal is to house hack within the next 2 years with an FHA loan.

These units are rare to pop up (I stay in one of the units each Summer) and usually are gone in a week....so I know the opportunity is 'there'.The goal is to relocate in 4-6 years and use this as a primary residence (but still travel and use as a vacation rental).I'm confident w/ the rental history of these units and comfortable with cash flow (hate having to initially throw down so much $$......but HI has their 'rules').

Moving to a dedicated flip 5, buy 1 buy strategy,  help me move away from a "transactional" mindset , flipping with no goal other than to increase the size and volume of flips (which was becoming exhausting) to a grower mindset.

This sounds like a great community and I am excited to connect with people with similar goals and interests.
