Cash out Refinance to purchase more properties

[Mary Javier]

Hello, just want to hear your advice if cash out refi is a smart move to fund the next investment property even if it means the mortgage will increase? We currently own 2 single home properties (one is rental and one is primary residence). Is it better to cash out refi the residence or the rental?   Our goal is to build our real estate portfolio and thinking on investing into fourplexes next. 

Thank you!
