People join BP every day and a large majority will never make a deal, investing in them would just be exhausting. 

I can cover about 200sf in 10-12 hours with the pad sander but it is exhausting riding that thing around all day.

We spend a ton of time finding the right contractors on jobs and its exhausting... 

The annual contributions are way higher than an IRA or SDIRA (about $59k/year), you can buy real estate, be a lender, take loans against your asset balance, buy into syndicates partner up with other businesses on investments, and a host of other things, as long as it's PASSIVE INCOME (ex, no buy/sell type transactions.)

The yard is manageable for me at less than an acre.

This is not passive investment for me.While I still work in what I used to teach in, adult ESL, I have mostly traded in one dead-end poorly-paid job, teaching, for a much better-paid one, rehabbing property acquisitions into rentals (which I spend a lot of time on), and managing rentals, EXACTLY as @Jay Hinrichs said, EXACTLY as I said in my first post in this thread.As @Randy E. pointed out, I too usually spend less than an hour per rental per month on average managing them.

A few weeks ago we actually closed one at very low LTV (like 50%) because it was a 1031 exchange where the borrower exhausted some of those funds for maximum rate buy down and ended up pushing it a hair below 7%.

@Benjamin A ErsingA down payment is different than an expense, so purchasing another property by itself would not offset income.

Obviously, a single fam B grade 3 br 2 ba house is completely different than an A+ luxury apartment, and rent increases may look completely different at each of those properties (even if they're in the same neighborhood).2.

I spend less than an hour a month and occasionally have a run where I do more if repairs are happening etc- the rest is on auto pilot..
