How to add 301 redirects for multiple paths

Hi – I’ve tried research this myself but am actually overwhelmed by too much information. I just changed my theme and now have a bunch of crawl errors in GWT from disabling a plugin that had generated its own paths. I now have crawl errors that look like:

properties-home12345
properties-home38295
properties-home49283

and so on. What I’d like to is to redirect all paths that contain the path “properties-home” to another directory of my choosing, like simply “properties”.

I already have many 301 redirects in my .htaccess which I don’t want to alter, so if your suggestion involves editing that file, please be aware of this.

Thanks so much.
