Much cheaper and easier to run plumbing without breaking up concrete. 

What kind of plumbing is in the walls on a 100 yr old property, etc...These properties will be management intensive and even if you're outsourcing that, you're likely to get a stream of continual invoices for work being done and dealing with high vacancies.A PM in Milwaukee was just telling me about a client that was determined to buy a three family in a real war zone, because hey, it only costs 30k!

They could do "improvements" to the property like moving a wall because it gets in the way, or rewiring a few outlets because "it's fun" or re-plumbing a bathroom or two because they want the shower ""over there".20.

There are some repairs that can be done while all three units occupied (basement windows, lally columns, and some plumbing) so having consistent rents coming in during the couple of months would be great.

My current project I had to rip out most of the Sheetrock in the basement due to water damage, and move some electrical in the kitchen, and some new plumbing drains in the basement bath but the rest is cosmetic. 

I have plumbing problem ill need fixed and am interested with getting a few split systems installed.

GC to manage the whole process or do you have specific trades you are in need of like paint, drywall plumbing?

Like next to a utility room that has plumbing in & out?

All new exterior, electrical, plumbing, roof, furnace etc.  

There were a couple of things I looked over on the inspection report like a slow draining bath tub that ended up being a $250 plumbing bill for me.
