Cash out re-finance advice

[Toni Conway]

I’m a rookie that just bought my first two long term rentals in Austin just quickly without a lot of self education first. 
I bought the first one in cash ($290k) and second one with $150k down on $370k house... definitely ill advised and know I need to fix. 
Fortunately both are renting and cash flowing but I’d like to get money out to invest in a multi family #-plex next. 
What advice do you have for the options I can explore and do you recommend lenders featured on bigger pockets or finding someone local in Austin where I'm investing. (Really need a REI mentor big time).
Thanks for your help!!!
