How nice to make low-income rentals look?

[Larry T.]

How far do you go and what is the minimum you do to make them look nice and welcoming without spending unnecessarily?

Also, I always seem to find ones with fake wood paneling, in this market is it worth having them sanded primed and painted by someone? (I cannot do it myself) They are not bad just dark and kind of depressing but that's my perspective, not sure if the tenants care or not or if I should worry about it even if they would like the walls a light color.
