New - Looking for advice on our real estate holdings

[Keiko Bake]

Hello BP,

I'm a former Marine and was on a plane with a Sailor  (CH53 pilot) when we started talking about real estate and he introduced me to BP.  It's now been a month and I've listened to over 30 podcasts and am now just getting into communicating with the community.  What an awesome place.  I've definitely grabbed the Kool-Aid jug and am ALL In.  Love the podcasts and the site so far.  This is one of my first posts so my apologies if I broken some posting etiquette.

Having said that, here's our (My wife and I) real estate situation:

We currently have 5 rental properties (single family) and a home in San Diego. 3 of the rental properties are in different states (accumulated through my moving and were Primary Residences over the past 17 years) and 2 of the rental properties we've accumulated as previous residences in San Diego. 2 of the 3 out-of-state rental properties are cash flowing with a total $800 cash flow (after expenses with the non-cash flow costing around $150 per month) and each property with a 60% LTV. Our 2 San Diego rentals have a $1000 cash flow with a 50% LTV. All homes have

Our Goals are to significantly build out rental portfolio (exponential growth over the next 10 years and currently thinking  multiplexes) more than likely outside of CA (thinking Syracuse NY, due to awareness, potential and family location) with the ultimate goal of transitioning from our W2 jobs to full-time real estate.

Key Questions:

1. Having being introduced to the BRRRR strategy, inadvertently through the years (thanks for putting a process around it), what is the best way to effectively/efficiently pull cash (minimizing overall costs) out of our current properties in order to fund future purchases? Or is there a better way to fund our future purchases?

2. Is there a Note strategy with our current properties that may allow for a better approach on maximizing cash flow?

I look forward to hearing feedback from the BP community.  We're in San Diego and very open to meeting great people with similar interests so if there's a meet-up, please let me know. 

Good Investment Building to ALL,
