Newb - Refinance Question

[Joseph West]

Not really sure WHERE to put this.  I was always told if you have questions on here; ASK THEM...so I'm doing that.  

It's regarding a tri-plex that I recently moved from (was house hacking); and am looking for creative ways to pull cash if possible.

Current Loan Age:  14 Months

Current Loan Amount:  $287k

Interest Rate:  3.625

Approximate Appraised Value:  $405k

The area where the tri is located has completely blown up; it is a bit nuts. Should I look at refinancing the home to pull out cash for REI; or is the Interest Rate too low to make that decision financially feasible?
