While doing all this, you can share your experiences on social media to attract people willing to invest their money with you.

Curious to methods people use to find distressed properties or is it truly just searching through listings on zillow/Redfin etc Yes that can be effective for finding deals but if you really want to rank out up you need a motivated seller website SEO optimized and you can run ads on google adds and social media.

You do a Google search or look on any of the social media platforms and see 100 people trying to sell you a get rich quick real estate investing strategy or whatever it may be. 

Looks like you need to talk to a tax advisor or read more on RE tax implications. 

Is it necessary or is social media sufficient? 

The big influencers on social are still talking about forbearance and foclosures - if I do some napkin math and divide it by 50 States, that additional inventory (most will sell, not forclose) will not amount to enough to fill the market.How will we get out of the inventory shortage?

HELOCs will give you powerful "check-writing ability" that works well for flipping homes, doing BRRRR style investing, and similar, but can lack the stability of a refinance.In light of the current chraos (crazy chaos . . . the only sufficient description of our social, political, and economic policy interplay right now) I'm personally looking to secure as much good debt as possible, amortized for the longest period, for the lowest interest rate.
