If you reinvest the cashflow you'll be able to scale a lot faster with the 30 year mortgages

I currently own one two family and want some advice on how to scale with little of my own money to get to achieve my goals.  

If you are interested in scaling, this will make you an excellent project manager.Because of your experience, I would strongly suggest seeking out an experienced investor partner in the area who has access to deals and capital, but may not have the time or desire to be involved in the day to day project managing of multiple flips.  

It is a great way to start to scale up.  

What makes it even worse is that I have been in real estate investing for about 20 years now....just on a small scale, on the side as a sole proprietor, with a rental and have flipped a home, which made a substantial profit. 

But playing devil's advocate: you won't be able to scale your business if you keep doing it all yourself.

I want to record my experience, help newbies but now I'm think longterm...how does this website scale and how can I protect myself?

This is a business of scale.

Make your mistakes on a smaller scale before you start borrowing other people's money and making mistakes on a bigger scale.
