They did not make me aware of the daily compounding interest this would cost me.

It is not really apples to apples, but generally speaking the more money invested the further ahead you will be eventually in the future, just because your compounding base is higher, regardless of where the money comes from - ie, 4 300k properties are 1.2 million on property, which is double the 600k property.

It grows so much faster and that early growth compounds over time, so having a little more invested early on is worth more than a ton invested later.There is a metric called cash on equity return.

Your ROI needs to be much higher the older you get started because of the loss of the magic of compounding. 

Additionally, don’t overlook the opportunity cost of pulling money from your 401k—those funds could have been compounding in the market.I’d also suggest stress testing your ROI by running scenarios with higher expenses or lower rents to see how resilient the investment is.

This isn't just high risk your talking about Zach, your talking about compounded high risk. 

Long-term planning allows for steady growth, compounding returns, and the flexibility to adapt to economic and societal changes.

This strategy lets you keep your equity growing and compounding, year after year, property after property.

Once again, the loss of the compounding factor by concentrating on my personal home rather than an investment was significant. 

They all seem to be fascinated by, and inexperienced and unknowledgeable about the concept of compound interest.
