Personally, I won't buy property with such suppressed rents (unless I can significantly improve them). 

Flood zones, train tracks, industrial areas, etc. tend to suppress land values which means that the other residents are likely to be in a lower income and education demographic.

Due to the water used during fire suppression, every wall has been damaged and must be removed and replaced. 

Perhaps, you can make BP's terms a little more clear.It seems to be okay to offer free advice and help other investors.It seems to be okay to put the website addresses and contact information for vendors as long as the BP members are not affiliated with the vendor, or directly selling services for the vendor.It seems to be okay to put my website address and my youtube videos in my BP profile where BP members can access the exact same information that I include links to in my posts.Can you please tell me why I am accused of 'self-promoting'  and why you are removing my posts when you allow the same information to be accessed in my profile and when I am not selling any type of service or product.My thought is that removing my posts and access to my videos is suppressing information that is useful for investors.

Is there fiber in the building (or to the building) and is there a fire suppression system.

Kitchen fire + no commercial kitchen built in fire suppression system + no insurance = ?

Specifically fire code; fire escapes, fire suppression systems, stairwells, doors, etc.2) Insurance costs.3) Elevators.4) Parking.5) Security.These are over and above what I would already be looking at with a single story garden style complex.

Continued new construction in the area will suppress the value of your purchase, but not depreciate it.
