Should I update the kitchen?

[Loc R.]

So...the kitchen in one of my rentals really bothers me. It's really old and tired looking.

It's apparent that the cabinets have about 20 coats of paint on them. Some of the cabinet drawers don't slide/close nicely or flush, some of the doors/hinges are warped.

The tile on the floor is an off-white; not sure if that is what it's supposed to look like or if that's just the result of years of abuse.

The tile on the counters are small (4x4) white tiles.

The last time I had to go through it, I repainted the cabinets and had everything deep-cleaned, twice...and it looked "OK" at best.

I don't know if the return will justify the expense...I rent the place out just fine, but in the back of my head I feel like I'm bordering on disinterested landlord (slumlord?) with it.

Any thoughts or suggestions?
