What does a "cash buyer" really mean?

[Chris Haas]

I want to understand what a "cash buyer" really is. I read lots of posts looking for cash buyers. So my questions.

Is a cash buyer really using cash, or is a hard money loan or even personal home equity line of credit being used most of the time?

What makes a cash buyer so much more attractive?

Is there a certain $$$ price limit that lends itself to cash buyers? Like distressed homes selling under $20K perhaps?

Lastly does a cash buyer often not need / want an inspection because they do it themselves? I assume even a cash buyer would want / need title insurance, perhaps they would skip an appraisal.

I tried to find some answers on these forums but it just seems like everyone assumes everyone else knows why cash buyers are nearly essential.

Thanks for your time
