I wouldn't worry about it, unless it seemed like something else weird was going on - like you though it was just a place to manufacture drugs or something.

My neighbors said they are 99% sure there is some sort of drug operation that the tenants are doing out of my house in Hawaii.

From my own experience, if I simply stick to these items and know nothing else, I manage an excellent batting average when it comes to tenant selection.First off, if ANY of the adults who will be on the lease have evictions or violent or drug related criminal convictions, I reject the entire group/family.

There is also a page they sign that says they are out in 24 hours if there is any drug activity, and another stating if they want to grow their own medical marijuana (legal here) then they have to get their own liability insurance.Things I added include that the tenant is responsible for replacing light bulbs within their unit, they are responsible for clogged drains and my use drano, replacing a missing smoke detector will be $50, no flushing things other than human waste and toilet paper- no flushable wipes specifically.  

However there have been numerous reports from other tenants of illicit drug use to the point where it is affecting the health/peace of the other tenants.

Even though I wanted her to stay because she paid on time, I found her to be very demanding (she did all sorts of bizarre things like claim the neighbors were drug dealers, stalking their activities, hassling others in the community, continuous repairs - I have other properties and no one is as high maintenance as her) and I was upset at the state of my newly rehabbed place.

Landlords who don’t want tenants who are going to mug their neighbors or deal drugs will now be treated as racists and potentially sued.Last week, the Department of Housing and Urban Development issued new guidelines to landlords, warning that bans against renters with criminal convictions violate the Fair Housing Act because they disproportionately affect minorities.In effect, the Obama regime is now outlawing criminal background checks for apartment rentals, even though such screening is critical for the protection and security of tenants and property, and serves a legitimate business need.In a newly released 10-page missive, HUD warns landlords they can be held liable for discrimination if they deny housing over criminal records.

One of the existing tenants has informed him that he suspects the new tenant of dealing drugs.

You only have yourself to blame if your tenant doesn't do the right thing, or maintain your property well.I meant with my agent who owns a property in the high class suburbs of Atlanta, and he seems to having if not the same, but more issues with his suburban tenants with drugs, headaches and disputes, then another individual would have on section 8. 

When I received information that one of my tenants was a drug dealer I took the advice of a prominent defence lawyer here who had previously worked as a prosecutor.
