A great question.
My observation is that leveraging a simple business with which to eventually fund real estate is a common approach.
Ray Kroc did so with McDonald's.
The family that ran the bodega in my neighborhood in New York did so.
The pizzeria owner in my home town did so.
In each case, the eventual real estate investor found the least capital intensive cash flow generating business with which to fund higher value investment in real estate.
They each organized a simple funnel.
Low capital, cash flow generating business to leveraged investment in rental real estate to passive income and wealth generation with tax offsets for them.
Most people place themselves in the first position of the funnel with their own job.
But a business can serve the same role.
The simplest formula I have observed is:
Get a steady job
Buy an inexpensive primary residence
(Not your forever home but something lots of people live in in a safe but inexpensive neighborhood)
Rent out the extra rooms while you live there
Save money by living for free at your roommates' expense
Buy a second similar place with your savings
Move out, rent out your first place fully, and repeat the process
Good luck,
