Can someone explain Seasoning?

[David Woz]

I'm looking to pay cash for 3-4 properties in the next year.  My primary reason for paying cash is to be strong in my offers.

My goal is to pull out money but still maintain a 30% or so equity position in each property shortly after the purchase.

I have heard the term "seasoning" before and always see it used when refinancing property.   Will I have issues pulling money out of properties after paying cash for them assuming appraisals and everything are in line?

My wife and I have credit scores in the 800's and significant cash reserves in place.
