@Michael Ealyi wish I understood that lol but I’m new to the game and have little knowledge on this stuff.

For plumbing they generally (it's different in different cities) will pass the rough in inspection first, then you have to do the other stuff (like install the bathtub and fill it with water) and pass that stuff before you do the wall tiles etc.  

For multifamily i'd focus on stuff newer than 1950 so your maintenance costs are lower.

One thought off the bat: how did you arrive at wanting "generates cash flow of roughly $800/mo" and what is your goal, budget, and plan to do so?

Now that was my first event and I don’t know if they are all like that, but I feel bad for those who feed into this stuff. 

When talking with people they would ask about my experience and I would inform them about doing stuff for myself and I'm looking for side jobs. 

It'll be a regional bank doing them for a loss to build karma, or to check Community Reinvestment Act boxes, that sort of stuff... still kicking and screaming, but they'll do it, they have some incentive other than making a buck on that particular loan (they won't). 

Redfin, Trulia etcSolds - Same as aboveTax data- Title Co's, etcThere are paid services out there for all that stuff depending on what you are looking for.

I definitely need to check out the podcast though, and I wasn't familiar with David Greene's stuff, so thank you again for the tip!

Contractor problems, small typical stuff, unreliable, not completely honest and forth coming.
