The optimal thing is to not mix them up.

Research Search Engine Optimization, consult a SEO professional.7. 

I was thinking maybe a session on building a basic website for real estate investors, real estate investors guide to understanding social media (maybe a four part- 1) understanding the platforms & identifying what works for you, 2) optimizing and measuring success and analytics, 3) crafting the message & building your community, 4) managing the process and content creation calendars). maximizing technology/automation for your real estate investing business, email marketing success strategies, and whatever else real estate investors wanted to learn about to DIY on the web.

Where would you say that number is optimized?

I'm very excited about this, because I view it as a way to optimize my opportunity cost in life.

Congrats on having the foresight and maturity to start at such a young age.My knowledge and experience are limited, but my optimism and positivity is not.Let me know if I can ever help.

My understanding is that if you get someone to partner with your SDIRA/401k, they are a managing partner of the JV, and do not need a license.So this leads me to the optimal SDIRA/401k cocktail ...1) Say 20% in cash from your SDIRA/401k, with proof that it could have bought the property on it's own with a non-recourse loan.2) say 75% from you as a mortgage, with proof that you could also have bought the property another way.3) 5% from a non-disqualified party who will act as a property manager without a real estate license.

I understand cash will be optimal but what are the options if it will be your primary residence?

So then the question is, what is the math that goes into finding the optimal building size?

Learning from others first would be optimal!
