Insight needed on Refinancing

[Geni P.]

I am looking to see if it is possible to refinance one of either of my two houses in order to pull cash out to invest in additional properties. I would like to know what my options are, and if this is even an idea worth pursuing? My first house I have owned for 2.5 years, I owe 84k at 5.0% 30yr fixed it and it is possibly worth 112k. House number two I have owned for a 1.5 years, I owe 110k at 5.875% 30yr fixed and it is possibly worth 158k.
