Buy whatever you are comfortable with plunking down the $$ for and never seeing the $$ again.
Even if you buy a brand name guitar, the resale value
is a moot point unless you find another lefty.
I forced myself to learn how to play bass right handed even though I had learned to play guitar mediocrely left handed as a kid.
I never felt entirely comfortable with my skills picking, plucking, slapping, or strumming right handed on the bass but more than made up for it with hammer-ons and pull-offs with my left hand.
A few years ago I bought a POS telecaster knock off on flea bay, left-handed,¹ and was shocked at how much more confident I felt with my rhythm and timing right off the bat. Without having to consciously focus on them.
If you buy a POS guitar don't take it to your local music store and ask them to do a set up.
They'll just do a half assed job and tell you the problem is with the guitar.
Find an independent instructor and take a few lessons, if there really are any problems with your guitar, if they are worth a crap, they will help you fix them.
(They want you to keep playing and paying for their lessons.)
YMMV
