On the low end in California I see custom houses get built for $250/SF + land acquisition costs - on the higher end I've seen easily over $1,000/SF.Easiest way to build would be to find a partially developed piece of land off an existing tract where roads, utilities, and zoning wont be an issue and you wont have to go through lengthy entitlement processes.

I find that finding reliable and quality service vendors is a numbers game just like getting good leads.

I wouldn't be surprised if a veteran in the game is impressed with you being so interested at your age takes you under their wing as a mentee, or even some sort of unpaid intern type gig.As for investing your current $$, I'd say open a high yield savings account (Ally, Citi, or Marcus by Goldman Sachs) and start stuffing money away from your part time job or side hustle, and save towards a down payment on your first investment property. 

The old adage "location, location, location" rings true in this game.  

Why do you want more real estate when you just got into the game?
