This thought led me into studying about becoming financially free and building generational wealth.

but without the whole "broadcasting" thing that you mention, I don't think I would have generated the outreach to the people of my age today who ask me for guidance on their first investment.

The pay stubs can be hard copies or digital PDFs generated directly by your employer and sent via email; we cannot accept screen captures to verify income.Once your completed application materials have been received and it appears that you would meet our qualifying criteria, we would send you a link to perform a credit/criminal background check (this minor expense would be yours), and if those results come back acceptable, we would offer to proceed.

I do not see a need for extra cost or tech not all of your guests will appreciate (i.e. older generations).

I'm struggling to generate extra lead flow from builders, mostly because it's so difficult to identify folks that are doing ground up, business purpose construction. 

No pocket listings = agents aren't even calling for new leads anymore, rising interest rate has nothing to do with an agent's ability to generate leads.If you mean multifamily apartments, 5 units and up, some of those agents will know, but not many until you are over 10 units which are more listed by only commercial brokers which I agree do understand seller finance.

Purchased and sold on the same day, it generated a $50,000 profit.

If I assume this is a rental property, your income isn't over $150k, and you're not a real estate professional then the losses the rental property generates could offset other income up to a certain amount. 

I may try a few more "flips" just for fun, but I also have money invested in Groundfloor, Fundrise, and other income-generating investments to compare (and those ones I spend little to no time on). 

What this implies to the typical RE investor is obtaining significant cash flow is a big challenge right now and relying on other RE profit sources (such as a value add and not doing a value subtract) may be a more certain path of generating returns.
