You should get these things for all applicants:1. rental application with employment reference and personal reference2. credit3. past landlord reference4. check for eviction historyMost apps like RentSpree include all this in what the tenant pays to send you a report.I cosigned for my daughter and her boyfriend on their first lease.

Since your a hands on person and have contractor contacts.  

While I haven't personally experienced any negative impacts from this fraudulent listing, I'm concerned that it could mislead potential renters and cause them financial distress.

Hire a company/person that is solely a QI like @Dave Foster they do it every day and will keep you legal and on track. 

It should go away.If it's only them smoking and a personal issue, I would reconsider dropping this if they are otherwise good tenants.

Personally, I've been in the mobile home investing niche since 2007.

However, I also have ways for them to pay with cash, card, money order, cashiers check, and personal check.

That's the way I look at things personally. 

Plane, Train, or Automobile and meet in person.

Personal recommendations don't always work.
