The current plumbing stack iis not connected to the man line.

Is there plumbing?

So now that it is empty, I have been doing as much work as I can myself, such as painting all the walls, replacing damaged bricks, drywall repairs, AC duct repairs, plumbing repairs, and simple electrical stuff to save money, but do not feel like I have the woodworking skills needed to install cabinets or siding and have it come out looking professional and clean.

 This house im am locoking to fix and flip does not have the plumbing waste line connected  Couldnt have a sewrr scope (see photos).

I get a hold of this girl upstairs and sternly explain that she absolutely can not allow water to go all over the place and how she has now caused damage downstairs. ...All bathtubs I have ever seen that were properly plumbed have an overflow, behind the shiny plate or lever near the top of the tub, which directs into the drain any water trying to get above that level.

As you know labor is the biggest expense and sometimes the owner can float out a lot of the expense on time for the products.A good example of this is a 4 plex that needs complete rehab minus major electrical or plumbing and the bid from the contractor may be $44,000 in labor ( $11,000 per unit )   The contractor may suggest I will take half of the first two years of rent or the equal of same. 

Enneking Plumbing and Fosters HVAC.

Many of the cleaners or contractors locally will have a network of people for handymen, HVAC, Plumbing, etc. so reaching out and setting an agreement in place has been helpful - if you agree to be on call for us, we agree to pay you $$ for the service call + any additional time and materials on top of it. 

In my mind, plumbing adds an order of magnitude in difficulty when comparing it to adding just a bedroom. 

We removed wall (plaster and lathe), added walls, re-did all electrical and plumbing, added half bath, full remodel Of existing bathroom, expanded kitchen.
