@Vanessa Gonzalez,  I will say I had to get a thicker skin to be a landlord.  

It's a little thicker than the typical dusk mask and had some layers that help filter out latex fumes.

Over the course of 100 years these have probably bio-degraded to useless pulp.If any of the bathrooms still have their original subway tile they're going to be thicker than modern subway tile.

The wood is very thick, probably 50% thicker than stock cabinets.  

Superpaint and/or Duration are good unless you need something to fill in cracks, then you can move into something more commercial-grade, like an elastomeric, block filler or even epoxy if that is the look you want but, careful, the thicker and more commercial the product, the tougher it is to get off if needed in the future and anything not water based, be prepared to toss out or clean with a chemical and not ever use it for a water based product again.  

With underlayment, people state what seems obvious -- that a thicker product will do a better job of deadening noise and perhaps of blocking moisture penetration through a concrete slab. 

Once the weather started getting better we started getting a lot more people applying.As far as developing a thicker skin, it takes time.

It’s property Incased in metal electric tubing with those thicker boxes for light switches, plugs, etc. you are right in that there might not be enough slack to go inside the wall but it might be possible as I remember the plugs being a foot or so above the baseboards.If I was to help the electrician fish everything, I am above average in labor, what do you think a ball park would be?

so i was hoping to just purchase bulk roles of thicker linoleum in sheets and glue it down to the porous cleaned concrete and install painted real wood or plastic (not mdf) molding around the trim for a finished look.how much would linoleum cost per sq ft and wheres the best place to get it the cheapest around here in LAcounty?

Thicker grass would be nice, but I am not sure it is worth doing sod.
