Invasion of privacy, unclean and rude house members, maybe if they do drugs or smoke or are party animals, unwanted friends of theirs visiting at odd hours, clashes of personality

But like I said we want a specific neighborhood so since nothing has been on-market there we decided to try to and test our luck.  

The real test will be when a tenant has an emergency. 

I'm trying to stay level-headed and unemotional about it (it's not going to kill my deal regardless), but this doesn't pass the common sense test.  

Once you have a shortlist, sign up for an account with each one and test them extensively to see how they function.

. $1 billion + so if you're going to go into a Section 8 area with a lot of crime and drugs, this is the one I'd do it in.

Fix that and re-test with a hose...

So many drug addicts in Seattle and Portland. 

If one resident relapses or brings drugs into the house, the residents resolve the situation themselves, usually by requiring the offending resident to leave for 2 weeks before reapplying for residency.

My recommendation is also to do a plumbing test while piers are dug up.
