Refinance then Home Equity Loan? or Cash Out Refi?

[Jace Im]

Hello BP family,

Being new, I'm still in the process of getting everything to sink in and digest with all these methods of financing options and need some guidance. 

My mom has a home (in her name only) and now she would like to add me as a co-owner to the home she currently lives in in Las Vegas.  

The loan balance is now 80K and home is now worth 170K.  I want to take out about 60K in equity (I have about 20K saved up) so that I can purchase more properties.  

Given my situation, what would be the best financing method?  

I would think cash-out refi would be my best option but then again I was also thinking of refinancing and then doing a home equity loan.

Can my mom and I instantly do a cash out refi even though I am not on the initial loan? or does it even matter? 

Thank you for your help!
