Of you did one you can do 2 then 4 etc.Wholesale takes a consistent commitment to marketing spend to be effective and build momentum.Retail flips are a great strategy.

One thing that was consistent, I found, was the description of their selling techniques as super aggressive. 

Turnkey investing is very dependent on the market the companies are located, level of involvement desired, policies of the companies, pricing, warranties, and whether they have in-house property management.For example, the seasoned turnkey companies realize that their demand is driven by investors looking for a safe, consistent return.

I think your first step is to educate yourself thoroughly on different passive investments that produce consistent income.

A marketing strategy consists of (1) committing a felony by not filing a tax return or by not declaring income on a tax return and (2) incurring interest and penalties and legal fees and being foreclosed on by not paying property taxes?

Obviously management is going to be more intensive as will some of the owner costs as community features usually consist of Wifi, common areas with respective utility costs. 

I tried a few meetups but with my shift, 1pm to 10pm, it is hard to find a consistent group.

Like 99% of people on TV or Youtube,  I wonder if he's looking for controversy or attention..... hmmmmmmmm....RE will be more consistent that the stock market for many many decades to come. 

It kind of depends on your needs-- my bank counts the full amount of the HELOC as credit card debt :(  So if you use all of it and/or don't make consistent progress paying it down, your credit score could take a hit.

Don't want to put the cart before the horse... and speaking from experience it can be somewhat challenging to qualify with limited work experience or in trades if there's not a consistent paycheck :)Any successful business will take some time to get up and running, wholesaling included.
