Have you looked at 2mm peel and stick vinyl tile/planks?
Here is why I recommend it.
1. $0.69-0.99 per sqft
2. Non-interlocking
3. GREAT over concrete
Pros:
If you damage a piece, you can lift the corner, peel it up, drop in a new piece and it cost you ~$1 and 30 seconds.
( I have done this SO many times after damaging pieces moving appliances etc)
We buy a couple extra cases and use the same pattern across multiple properties. I always take a case when doing turnovers.
Cons:
Needs good surface prep (flat smooth clean)
Needs to be rolled with a 100lb roller at least ($20 rental at hd)
Not waterproof over wood
Will curl in hot/humid/direct sunlight sunrooms etc without being glued down.
Applications we have done with success:
Floor leveler over existing tile bathroom then peel/stick vinyl tile
Over level wood floors (plywood)
Over existing linoleum
Over concrete
Over damaged and stained oak hardwoods (when you pull it up it does not leave a residue)
