Your philosophy is a lot like mine, that's how I'm getting into notes as well.

What is your sales philosophy? 

Some say never sell in order to create long term wealth, but others dispute this philosophy.

Plus with just 2 million people I feel scared I might not get renters as fast:I guess I am not fully understanding the real estate/growth philosophy.

The RDPD philosophy is correct, in that money should be spent on income-producing assets rather than luxury items.Save the 50k and use it to buy houses, IMO.

While I make a good living from my consulting business and love what I do, I recognize the tax advantages and growth potential of converting active income into passive income (big believer in the Rich Dad philosophy).

My philosophy is  - who am I to enforce my own aesthetic values on the folks who are intimately involved in the day-to-day use of the property?  

Dishwashers, W/D, garages, storage units, extra space, etc. get more rent.My philosophy is to split the rent increases with existing tenants.  

This might be a function of location vs investment philosophy.

But when you say things like "Because the interest is calculated daily, I can pay down principal much faster than a traditional mortgage," I can't help but think you're still sorta advocating the "HELOC saves interest" philosophy.
