It has gotten increasingly frustrating to deal with inadequacies and complaints from my tenants as far as payment processing.

in the desert units are often on the roofs.. you can only hope the criminal stumbles and falls off the roof and breaks their butt and decides thats not a good play for them..

However, if that effort fails, the local agent is equally liable – criminally and civilly – for any fees, fines, etc. associated with the property." 

The tenant hasn’t been the greatest: late payment with not always paying late fees, multiple complaints from the neighbors, changing phone numbers, ect .

We have to file the paperwork for the DC complaint.

I weigh more on making 3x rent and having great rental history of on time payments with no evictions, no lease violations or violent criminal history.

A local couple who’se combined income is 300K and who sponsored the family’s immigration to US is willing to be co-signers for the family of 5.I am thinking that Party2 will put more miles on the house and may be harder to deal with in case of any complaints or eviction, though I am not an experienced landlord so I am not sure what are the factors to evaluate or what all can go wrong?

Use services that can validate the authenticity of documents and employment history.Require Detailed Applications: Ensure that the rental application captures comprehensive information, making it harder for fraudulent applicants to provide fake details.Conduct In-Person Interviews: Meeting applicants in person can provide additional insights into the authenticity of their application and allows you to ask follow-up questions based on the details they've provided.Utilize Professional Screening Services: Professional tenant screening services are invaluable for conducting background checks, credit checks, and criminal history checks.

I don't try to evict based on neighbor complaints as those aren't super reliable and the people likely won't show up to court. 

Non-compliance can result in penalties up to $500 per day and potential criminal charges.
