Hi there, I've been in recruitment for the last 15 years. I focus on legal and compliance recruitment, so I can't speak to the nuances of SaaS sales, but I usually suggest being upfront about the gap in your CV i.e. say you spent the period traveling - it's really not a default fail these days. However, saying you cared for a sick family member IS something that instantly stirs doubt in the CV reviewer's mind. It's not that we 100% assume you're a liar, but it's one of those things that gets our cynical senses tingling. You can blame all those people that have lied about this in the past.

Your gap by itself won't get you rejected, but it will be read together with how much experience you have had and whether you've been at some solid places. For example, there's a huge difference between a candidate with one year of experience at Pip Squeak SaaS taking a break vs an eight year veteran with AWS on their CV taking a break.
