Buy and Hold - 5-6 year ...Napkin math

[Damon Tyler]

I would love your opinion - especially if you have over 12 3-4 unit properties. I have heard some guru's say "Buy and hold doesn't work - I got a ton of properties and never could get the cash flow to flow" - these are normally people selling notes or flip programs... 

Here is my napkin math for my 'plan'. If I buy in markets that are solid but I do NOT assume appreciation. If each 3-4 unit costs about $30K down and returns on average $100 per door net (or $400 per investment even if 3 fam) and if I invest $4-5k per month AND all of the cash flow from the rentals and just keep rolling the snow ball then...

Will I have created a yearly cash flow of around $85K?  People who have been here and have done something similar... does it actually work something like this?   What actually happens at what point do most jump up to larger commercial? Please share some details. PM me if you don't want it to be public.
