Hi Jermaine! Great question with so many options. Lots of good advice already. As a veteran investor of 20 years, here are some of my humble thoughts to get started. These are not in order.
1) Get involved with local investor groups, go to real estate investor meetups, network and meet people. You will find many people willing to share and advise. Just do your due diligence and make sure you connect with ones that are vetted and real. You will learn so much having your feet on the ground in your local market. You just have to be careful who you connect with and make sure they are what and who they say they are. You want to network with everyone you can, though you want an experienced investor with a track record that can guide you.
2) You will need to build a team. Find a good realtor or two that work with investors. Find lenders, contractors, suppliers, property managers, etc.
3) Find an experienced investor that is willing to help or coach you, you’ll be surprised. If you find the right person, it would even be wise to pay them. The right coach will teach you how to make money in this business which is priceless. They will also greatly expedite your learning curve. Again, make sure you vet them. You might even try to intern with someone experienced who needs help in their business.
4) Make a detailed plan, you may need help here. I can’t say flip or rental is best to start, it depends upon what you want and what type of deal comes to you first. You can with help minimize the risk on either one. Rentals are great to build passive income and flips for short term gains. Wholesaling is another option, though don't mistake it as being not needing funds and doing part time. This is a business like rentals or flipping. Decide where to start, it doesn’t matter, just start!
5) Learn as much as you can. Spend time on bigger pockets, lots of resources here. Read books, podcasts, audio, etc. Network at events, seminars, etc. Just remember, you cannot learn how to do this from books, you need action!
As Grant Cardone says, 1) Invest in yourself 2) Invest in others that can help you 3) Invest in your business. This is just skimming the surface. I wish you good fortune and if I can help in way, reach out.
