Be sure to have the gas, water and sewer lines inspected as these may be dug up or collapsed - and very expensive to replace/repair.

This way you are trying to get top dollar for it but are also going to be notifying those who have saved the property every time you drop the price. 

Could stocks drop a lot very shortly - sure.

I know this industry may be hit or miss, but if anyone can drop any kind of advice that would be great!

I think @Brian G. and @Jaycee Greene hit it on the head: an event occurring/debt resetting.When the debt forcefully resets on some of these assets, valuations drop if the submarket cap rate has expanded and/or if the operator can not show a good t-3, t-6 etc due to economic vacancy and rising opex (insurance, r&m etc).If the operator can't inject equity to cover the difference, then trouble arises.

Your question about hydrostatic pressure is getting into the weeds for sure...I would ask myself, does the potential water infiltration have the possibility to damage the unit and tenant property?  

My rental condo in Asheville, NC was spared damage from the flood, but when the city finally turned the water back on a few days ago, they somehow overpressurized and blew out a fitting inside a wall.

This may not seem like a big issue, but if you're paying for premium data, like I am, it can drive up your cost per deal drastically.I switched to REI Reply last year and can send off over 2000 texts in one drop.
