Newbie with refi questions

[Dakota Cochran]

So I know a lot of this depends on specific numbers but I will try to keep it simple. I’m trying to refi my Florida home, I occupy it, credit is good, income is good, increased value, and current interest rate is 6.5%. I wanna take advantage well I can and I plan on trying to buy a multi family soon.

My two questions are:

Should I pursue just a rate and term or cash out?

How do I compare lenders to know if I’m getting the best deal? Is there a  certain fee, percent or closing cost to use? 
thanks in advance, newbie
