I was with you until the out of area, hands-off part.We can add tremendous value ridding properties of undesirable people and conditions,  but it is far from hands-off.  

Do these things not present conflicts of interest and undesired competition?

So, management companies tend to rent to more-undesirable tenants whereas the property owner would not rent to those tenants and would leave the unit vacant longer.

Until the bank finds them or follows federal guidelines to replace them the right way.That way nobody is rewarded for their undesireable actions.Keith

The manager could issue a "Notice To Quit" to the upstairs, so that the undesired behavior of discharging a firearm on premises (without good cause) is not repeated.

Given the solid base of knowledgeable posters who post here daily, that goes a long way to keep the undesirables from feeling too welcome.Still, I think upping the minimum post count before someone can post in the marketplace forums would be a good idea.

I realize there are legal proceedings and other things that happen in the real world that make this undesirable, but in theory it would be beneficial.

If a number of years old, they may have cleaned up their act recently and might just be better behaved as tenants.If you are screening thoroughly enough, you should be able to identify the undesirables.

ugh.. didn't know this area is so undesirable.

Is this extremely undesirable to the end buyer, or is it not really a deal breaker?
