I bought a DSLD home before they built it and watched them construct it and live in a neighborhood that has had about 500 homes built in it in the last 6 years. 

You can quit your job and live of REI, but it takes on average 10 years of throwing everything you have in time, money and energy into this endeavor.I quit my W2 in 2015 and learned very quickly that you can watch only so much daytime TV.

I have bought recently plenty of deals in the MLS that hit the 1% rule some investors target.The wholesaler route can get you some below market deals but, man you have to watch those wholesalers.

And watching tons of tons of videos/podcasts  

@Bruce WoodruffJust watched a Tom Silva tutorial, it’s easy!

As you read these books, watch the BiggerPockets podcasts.

I can't wait to see- The fire in the sky.https://www.youtube.com/watch?

@Bruce Woodruff there used to be a TV show where they showed how they forcibly repossess these commercial properties, collect on judgement debts, etc all over in England.

By having more tenants there are more eyes to watch for issues that may pop up, more people paying rent, and if you have one of the units vacant for a bit, it will not hurt the bank as bad as it would if you only have two tenants in the building and one of them left.   

That new flat screen 60 inch TV you need for "zoom calls" might be a write off if your actually using it for zoom calls.
