They asked me to fix a few light bulbs, tighten a railing, touch up some chipped concrete, and fix some paint starting to chip on the outside.

Once done, I can back out the copper male adapter if it's not badly corroded and fused.Yes one of my fears is the connections are badly corroded which will mean replacing the fittings, and if i have a hubbed fittings with the bathroom double tapped tee on top with a street end into it, I have to mess with that it may turn ugly.Even worse if the pipe below that fitting has a vertical crack into the concrete slab.Or I can even tease out the copper pipe after having the two openings because it's strapped to the framing in between, or the holes are drilled so close a copper coupling cannot pass through.I may have to replace with same copper since PVC may be too large OD to fit through existing stud holes.

Concrete forms are secured.  

They have HUGE ceilings, exposed brick and concrete walls, and I keep finding all sorts of goodies when I look in the units from when the property was a factory.This last unit I looked out (tried to view before the next lease started on the 14th of this month) had some fire hose connector still on the wall.

do granite if you can find one of the independents with the tools/connections.... half bulnose/flat in a pattern and really common color.ikea has really cheap formica (almost to the point of per/renter  expandable) but you need a quick and good handyman.formica also makes solid surface (not just foil)... not sure how it handles a hot pot and knife cutting....you can also do really large porcelain/granite tiles (18-20"+ inches) with very thin grout lines...concrete can go with a very good sealer, and somebody who knows what to do.but in the end, you want something you can replicate again and again with not a lot of headaches down the road...continuous success

I'm looking for anyone with information on a ballpark number for the cost to build a 4-plex...all concrete/concrete block. 

Thanks, Jon.Doesn't that sediment turn into something like concrete?

a lot off shops charge cheap but their polishing and installation is also cheap. so in most off cases you get what you pay for.In NJ there is a lot off wholesalers you can buy a slab and do your own fabrication .a slab costs between 500 to 800.

Show her something concrete as well, actually have a property that you are thinking of to show her so the example isn't abstracted.
