The roof is fine until it leaks, decks are fine until they are not, things wear out, line blockages don't happen overnight they most often are buildups over time until the result IS seen overnight. 

Example $1300/m for rent + $50/m - water $50/m for gas/eletric

We're selling off a couple, keeping the easiest to manage, and using that capital to throw gas on our other fire. 

Hello, we sold a house and during the final walkthrough the buyers noticed the well pump leaking.

and that they are not able to fix the gas leaks until after the home is sold? 

RE Professionals should prepare for an active Q4 and investors looking to close deals before year's end are recommended to get their financing and property search profiles clarified, and then...step on the gas. 

The hired leak detection company states there is no leak, the roof has been replaced as a result, and the crawl space has also been encapsulated.

Each unit has its own electric panel, gas meter, furnace, water meter.

It's the same case for hiring a highly referred plumber who will fix the leak and a few other things for the right price, or take the new guy no one has ever heard from and your leak has now turned into an explosion. 

From the floor joist being cut from the sill plates and the entire house needing brought to level, the foundation requiring correction, to the no slope rubber roof leaking and needing replaced when I say I renovated every square inch of this property I mean that literally.
