We as individual paper investors can't compete with the high velocity trading computers exploiting arbitrages out there.   

I can see the brain drain for that. but not to buy notes or lend money.. just can't get enough velocity. 

The save and use compound interest model could take a life time and you may only reach a fraction of the 100M net worth figure or you need luck like others have mentioned.The quickest way is to do what the rich do and that is to do what JJ Marco focuses on in his book the Millionaire fastlane by either focusing on the 1) Magnitude or the 2) speed/velocity.Increasing Magnitude would be like increasing the ticket item size so if you're a real estate agent instead of selling 250k homes you sell luxury items that you receive your 2.5% commission off of 10,000,000 instead.Increasing Speed/velocity would be how many times you can transact and earn that commission above, profit above in whatever business model it is  whether you're a RE agent, you're selling burgers, or widgets. 

Top brokers want velocity of transactions just like investors want velocity of deals.

They were way to late to hike and are now arguably too aggressive but in the grand scheme of things we over printed (money that will basically be sucked back out of the system by high rates and the loss of velocity of money, for everyone taking about how much money we’ve printed right now the biggest issue the world economy is facing is literally a too strong dollar not a diluted one.) and avoided a much worse catastrophe where people starved during a pandemic.

Now, keep the velocity going.

I can see the following as options:Get rid of the steam boiler and install high-velocity AC/heating (seems like the best, but PRICIEST, option)Limit steam heating to a single unit and install electric baseboard heating on the other two units (perhaps the most cost-effective way to go, though I would still have to install separate AC window units)Limit steam heating to a single unit and install ductless mini-split AC/heaters on the other two unitsRepair/replace the steam boiler with another steam boiler, fix any radiators that have issues, and keep the status quo without zoning heat (not ideal - I can already imagine the third floor being one extreme temperature while the first floor is another)I'm really new to all of this and at a complete loss right now for how to proceed.

I think once the weather pics up sales velocity on cars like this increase so maybe get an ad going in a couple months. 

Matt, the appreciation rate may top off, the velocity of money, the time to recover the money increases the IRR as the return is measured over time.

Plus...escape velocity...Episode 113 – Jay Papasan - Very practical slow and steady adviceEpisode 221 - Tim Shiner - his concept of equity build up and "shearing the sheep" shows some of the flexibility of real estate vs a 401k Last but not least, I also recommend all the tax advice given by my fellow CPAs on the BP Podcast.
