Ceramic Tile is probably the right choice, especially if you're on a slab. 

okay here is a little story about this house. i bought the 1200 sqft house for $14k from a owner, and spent around 12k for remodeling such as a new wooden floor, paint inside/out , window and tiles and some new dry walls.  

Hardwood, parquet, faux-hardwood, tile, etc. are much easier to clean and you won't reduce your pool of potential tenants/buyers.

Also, tile in bathroom/kitchen. 

I’ve ran numbers on houses from the 50k to 75k initial purchase price but wondering if buying something more expensive is the better way to go as the “percentage” of repair cost goes down. ( example it cost about the same for new an HVAC system or shower tile) 

We refinished the existing hardwood, updated the kitchen and bathrooms, set new tile and backsplash, and added a utility room.

And someone saved you the vinyl asbestos tile removal/disposal headache but you can see the marks from the pull up....maybe some good bones left and ideally it looks better for the outside, so much interior work to go...Best of luck

If it is a slab floor, I would install the least expensive ceramic I could find.

I would have the saltillo tile professionally cleaned and it should come out good as new. 

Don't put things in that you would be dissapointed to have destroyed because it will be.I like fake wood floors and tile.
