I'll tackle one at a time.As far as saving you money, you will need to pull comps for properties that you pursue, or that pursue you (hopefully it's the latter).

I recommend professional training and mentoring for anyone wanting to tackle apartments.

If we know it is a rental and the owner isn't pushing us to finish so they can get back in 2 days before we agreed on, we can tackle multiple rooms at once and charge less for a PITA fee.

Since it's empty now and I have other rehab I am thinking about just tackling this now rather than later. 

They are taking on initiatives like Columbus 2050 to tackle the mass-transit issue. 

It doesn't take TOO much to bust up the concrete and lay a drain, but you have to make sure the fall gets it to a single point so a lot matters on what the floor in the basement is like.Its usually easier to tackle the problem outside, though. 

There is a little mold we have to tackle in the basement and asbestos around a couple of the furnace vents in the basement (scared the cr*p out of me when I first learned that) The inspector who has been working on homes and doing inspections for 40+ years said we can seal that asbestos and it won't be a problem.

For developers in Denver, City of Denver recently came out with some recommendations for tackling slot homes and rowhomes.

Builders are very busy in Denver so getting them to pack up and go to Eagle/Vail is a reach that most don't want to tackle.

This is not the type of thing that I would tackle on my own.
