1st Investment: House-hacking strategy

[Michael Bangsal]

Niche: Buy & Hold

Strategy: House-hack 1st investment 

Challenge: Expensive area (Bay Area)

I want to start my real estate investment by using the house-hack strategy for the first investment. I am open to a duplex or triplex. The issue is I live in an expensive area to start looking for this type of property that demands a high down payment. I want to move fairly quick with a second property without having most of my money tied with the first property's down payment.

How do I go about this? 

All input is appreciated!
