Many, many people on podcasts only have a few years of experience (not all, but like @Jaron Walling notes, you can save yourself a lot of time if you skip over the people on podcasts that have only been investing the last 5 yrs or less).  

A prospective tenant views the apt with me, and I tell them "What you see is what you get, aside from a good cleaning, if you were to move in here, this is how you would get the apartment" .....then they move in and it's "what about this little paint blemish on the wall, what about that 1 cracked floor tile in the kitchen" ......I shut it right down.

The walls are open so now is the time to install a wired system. 

Now the tenant is claiming the smell is back and is likely due to water getting in the walls from the toilet that was fixed and he wants the walls gutted and repaired, because he feels there is mold there.

Get the floors and trim done, then let the painters do their thing.Are you moving/deleting any walls?

We are leasing a large industrial warehouse for 2 years to utilize as a build space to build the walls and parts of the roof in the warehouse and then shipping the pieces to be assembled onsite.

Quote from @Jaron Walling: @Jenifer Garcia The theoretical example you provided is already a great deal.

Maybe they could use the mount that comes with the TV and set it on the mantle vs. the wall mounted one they have to pay for and then have professionally mounted and repaired when they leave in 9 months. 

We have a 3-story apartment building and are having major water (rain) intrusion issues along the back wall of the building.
