The thing about luck here is that it applies to not the refurbished sets but new ones too. Look at those with hissing issue for example.
Quality test wise probably the refurbished sets will be better I guess?
Actually my concern is more of whether next time I want to sell off the phone, will it affect the price.

Yep, there's always a bit of variation for buying new and also replacement. I've seen others complaining that their replacement phone produce worse hissing and with yellow screen while some fixed their problem completely. I would definitely prefer new though as the chances of having an issue should be comparatively lower as compared to a replacement phone which definitely have had some sort of issue before.
You can say that refurbished phone goes through a more thorough QC as it should be testing each and every component again to ensure no issue exist, especially when it has been returned for some issues before. Might have a different tolerance level compared to brand new but we would never know. I'll always treat replacements as brand new since we won't know what is new and what isn't. Replacement phone at this point of time should be relatively new as compared to phones that were released longer since there is no way your components can be more than two months old be it brand new or went through refurbish process.
Replacement phone should NOT affect reselling pricing, unless the buyer is an** about such things then he will nego for a lower price. If that's the case, move on to the next genuine buyer. If you can get a replacement phone for some reason closer to its warranty end and sell it shortly after, it should fetch higher price due to the new battery and component etc.
Since your issue is with the vol up button cannot be repaired and cannot be overlooked, you got not much of a choice anyway than to replace it. Just look at the positive side like I mentioned that the components are definitely not that old.
