Trying to modify purchased theme Texts

I have purchased a theme from wpzoom called domestica. I am trying to modify some of the native theme elements. For instance, when you view a list of properties it has a button that says “View Listing”, I need it to say “View Home” I don’t know where to go to change this. I also have a few other changes that I would like to make but I think if I can figure out where to go to find this change I may be able to find the others and if not I will come back here and ask again. Thanks in advance for your help.
