My short term goal is a BMW, although would like to grow my real estate empire to the point where it would be equal if not greater than the income I will receive from industrial engineering.

I know many can't do this but the brrr strategy seems like it is really hard to pull off, and I can imagine feeling like what is going on when you look at your account but never really see it grow and you own properties.I guess if you want to expand as big and as fast as possible brrrr works, you are really leveraged, and you have a bunch of properties, and if everything goes well, you could do what I do and roll all the profit to pay down one and still pay it down quickly and soon it would become a steam roller of fully owned properties.I just can't imagine being able to find all these "deals" and expand my empire that quickly that I would be able to get the returns I feel comfortable with. 

While it's not impossible to start your empire on an investment property the financing may be easier if you use it as a primary residence. 

If you were in my shoes, what approach would you take to building your real estate empire?

I live in Newport Beach but most of my long-term investments are in the Inland Empire (Murrieta, Temecula, and Menifee) area.

I live in Newport also but most of my long-term investments are in the Inland Empire area.

I am new to Biggerpockets and Real Estate Investing, looking to network with other wholesalers and investors in the Orange County and Inland Empire areas.

The Bible has figs and an incorrect value for pi and the Roman Empire hard coded into it -- it may be a great place to draw wisdom from, but pi is still 3.14159(...) and not the number they have it as (also what the heck is a fig?).

They wanted to team up, invest a large amount money and start the ascent to building our real estate empire!

I prefer having silent investors who will be happy with the returns than having a person think that they should always have a say and right to block certain decisions simply because they are either scare or on an ego trip and think they are now running some sort of mega empire and that they will save the world.Doesn't mean it will happen, but I have learnt to do my researches, plan things out and be smart with my money.
