Search volume is a narrow-sighted way of looking at a domain.
It doesn't mean much. Equally important questions are which niche, how much does it pay.
Search volume doesn't mean there will be traffic, buyers or will be easy to monetize.
Instead, ask yourself if the name makes sense on its own, why it's not registered if it's really great. Sticking two keywords together doesn't automatically make a meaningful domain. IMO it's best to focus on industries you are familiar with.
You can still resell a developed domain, then you are actually selling a website. The value will stem from contents + SEO, more than the domain itself that could be very average.
