sacrifice cashflow for another rental property?

[Joe Capobianco]

Since the interest rates dropped I decided to refinance my rental property into a 15 year mortgage which raised my mortgage $200. The mortgage now is $1200 and im receiving $1750 per month in rent. I just received the appraisal that needed to be done prior to closing of the refinance and realized it was appraised about $60k more than I was expecting. right now i'm kicking myself for not keeping the cheap 30 year mortgage and doing a cash out refinance and buying another property. I believe I can call my lender in 6 months and do a cash out refinance but that will most likely take away the cashflow im receiving from this property. 

  im writing this post see if sacrificing cashflow for another property would be worth it or if refiancing to 15 year was my best option?
