Who cares, especially when very conservatively, the ultimate passive income includes a six digit or more base lease, plus an estimated additional six digits or more for rate increases and another six digits for more for various smaller and one bigger technology increase at 25 years. All four (base, rate, smaller and mega technology increases) combined, certainly could yield much more depending upon inflation, rate increases and technology increases?

If you make the choice, it is binding for the tax year you make it and for any later year that you are a real estate professional. This is true even if you aren’t a real estate professional in any intervening year. (For that year, the exception for real estate professionals won’t apply in determining whether your activity is subject to the passive activity rules.)
Finding an outstanding development team is critical for success. Don’t just go for the lowest and cheapest price. You need a balance of budget and quality. From personal experience, I’ve had the best luck with developers from Romania. That is my number one pick. When you post a job on Upwork.com, everyone will be promising you world. Do not fall for a development team that does not have good feedback and return clients. Return clients are one of the most important. This means their client was willing to return to them for more work after their job finished! That says something.
I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so. I think it is something that you could do on the side, but you would want to do in depth research on the industry you want to get into before setting up shop. It may be a little less passive up front, but over time you could take your hands off the wheel.
