Determining Mac Replacement:

A. When to Replace it?:

When you no longer want to troubleshoot with it. I still have my 2018 MBP, and will keep using it, because it has an Intel processor. Many things just won't run on a Silicon chip.

B. Time-Limitation:

Note that Mac devices typically are supported for 7 years, and then updates for them are no longer available. So, getting a much newer Mac --one that is 5 years old or less is best, IMO.

C. Purchasing Third-Party Macs:

Avoid being Scammed: When purchasing from private party, have the seller go here: What to do Before you Sell, Give Away, or Trade in your Mac - Apple Support. That is the site the seller needs to use prior to selling it to you. So, prior to handing over the money, make sure that you can sign in to iCloud on this account, prior to handing over the money. If the seller decides to disabide by those rules you've set forth, then do NOT proceed with the transaction.

When it stops working and can't be repaired for a reasonable cost or when it will no longer run the software you need.

You'll know when it can no longer do the things you want it to do. OTOH we still use our 2008 for storing photos and watching home videos.
