Hey Zack,
I'm up in Maine so I'm not too familiar with the Long Island market, but there are a lot of advantages to investing locally, so my advice would be to buy local and house hack your first deal. When house hacking, you get much better financing terms (less money down) compared to if you weren't living in the property. Also, I know most people start out wanting to buy a duplex, but don't shy away from the three and four unit buildings if you find one that you like. More units typically equal more cashflow. You can get up to four units with an FHA loan.
My advice for getting started out would be to:
1. Go to a local meetup to network and talk other investors
2. Talk to a few lenders at local banks/credit unions and get pre-qualified
3. Find an investor focused real estate agent in your market. They'll get you setup with an email list and should be able to help you analyze deals.
4. Analyze deals every day so you get comfortable with running numbers. When you see a deal that matches your buy criteria, setup a showing.
5. Make offers on properties - this one sounds obvious but is important. If you are analyzing deals but not making any offers you won't ever get a property!
What are you next steps to move closer toward your goals?
