Hi India,
No need to be a real estate agent to begin investing. It helps to write up your own contract and represent yourself so you can save money on buyers side commission. If you think those are some good perks then I would say go for it. The great thing too of being licensed is that if you end up loving real estate that can be a source of income for you that can possibly help you get to your real estate investment faster as its a high ticket sale with the possibility of earning great compensation. Having a high income will also give you an advantage to get there more quickly.
As for gaining knowledge your in the right spot reading other peoples forums on Bigger Pockets is a good resource. I would also look into Real estate meetups in your area to meet other like minded people and discuss whats worked for them and maybe you'll find a mentor at those meetups.
When looking for a lender I would suggest to work with a lender who also is an investor themselves as they will be more familiar with the guidelines for investment properties and how to strategize when buying your first deal while also already pre planning your next purchase. Theres different strategies to make sure your set up for success. You dont want to be stuck after your first deal.
Lastly Banks are more strict and when working with self employed and real estate investors. I highly suggest working with mortgage brokers.
Good luck with your real estate journey.
