These are all great questions
Getting your real estate license will help you save some money procuring your investment properties so yes I think that’s a good idea to invest the 40 hours for your license
In real estate the way to Find clientele or investment properties can be done in a multitude of different ways.
There are laws that prohibit you from going behind the sign and calling the listing agents sellers directly not to mention it’s unethical
I think the best way to find Sellers who want to sell multi family, Duplex & investment properties Is simply by calling from the Whitepages on Properties with absentee owners or driving by. but Never call behind the sign
Another great way to find investment properties is with a relationship of a trusted real estate agent. There’s a lot of pitfalls in investing in real estate if you don’t know what you’re doing you can get financially upside down relatively quickly.
My advice to you is to secure yourself with someone who works with multi family properties to learn how they did it and who they use in your area before jumping in head first.
