But I am open to ideas.I see this environment as quite challenging to find a deal that will cash flow reasonably well in my area due to HCOL and interest rates (even as somebody with some resources). 

The only way to answer that in general (whether house hacking in today's market is still a good option) or for a particular property, is to learn how to run the numbers and analyze a specific property to see whether it will be able to stand on its own as an investment when you move out someday.There are a lot of resources here on BP for doing that but I'd just say, make sure the assumptions you're putting into your spreadsheet or deal analyzer are realistic.Make sure the rents (especially for vacant units or pro-forma #s) are realistic by doing your own rent comps; make sure the mortgage rate is realistic by doing some research online and/or talking to some mortgage folks; make sure insurance #s are realistic by getting a couple of quotes for the # of units and zip code / area you're looking in; etc.I hope that helps, and good luck 😊

Small entrepreneurs should not diversify their limited resource if they want to grow.

Can anyone suggest training videos, books, or other resources that would help educate me on the topic?

What resources do you use to do market analysis and what are the nuts and bolts of using those resources to actually narrow down a location?

I just feel like you’d be way better off joining one of the larger multifamily networks that has actual resources and successful students.I really truly believe that Ryan and Tyler started off with good intentions, but I feel they saw how much money they can make off of tuition and have made a ton of promises that they haven’t kept.

I have resources I use to get an estimated idea of that, but always good to hear from someone whos already in the game.

Lots of methods and resources.
