Funding my business so I never realized the profit from my job, nor I consumed it, it was invested.

I am not new to investing in general - I have a passion for stock/stock options trading, but I have always loved real estate and now have caught the bug to make it a reality.I am in the Boston, MA area, and realize the market is very expensive.

Only looking back do you realize how bad it could’ve gone.

With the immediate impacts of the pandemic, that realization immediately vanished. 

In my experience, a lot of commercial investors will defend an investing strategy if it is something that made them wealthy with not realizing that trends change slowly over time.

The sellers who took their home off the market has placed it back on the market after realizing people are still moving too/purchasing homes in Las Vegas, NV.  

Some were inept, some just realized it would be too much work. 

I am in the same camp as you but also realize the opportunity cost and the ability to acquire more properties.

You have to have contractors if you aren't handy with a hammer, you need to buy well below what you will sell it for, you have to be able to accurately estimate what it will eventually sell for, you have to consider acquisition costs, rehab costs, carrying costs, selling costs, prepare for 6 months on average from start to finish, you need to know about title reports, appraisals, escrow, lenders, insurance, sequence of rehab lists, "oops" surprises, market changes, level of finish, what other rehabbers are using for materials, and realize that contractors don't always show up or finish what they start.

It will be much hard to fill units at that rate, and if you do find anyone, those tenants will quickly realize they have better options for the same rent amount elsewhere, so you'll have high turnover which is number one profit killer IME.
