Failure to disclose certain life endangering issues may be considered criminal.  

My biggest problem right now are probably things you already thought about, but my ignorance has caused me many issues: have a visitors clause in your lease, and on the application be sure to ask about past criminal history.  

Focus on screening your tenants effectively, checking financials, credit, criminal backgrounds etc...

Tenants will have bad credit and often criminal records.

.- friend submits application after a days online after a day.Several back and and forth for corrections and then based on his checks, income vs. spending more than earning (has traffic / DUI related misdemeanor and criminal tickets; several traffic citation; spending more than it's earning;  has considerable debt) , I informed him that I cannot rent him based on what income information and reports I see (this is prior to employment check).He then decides that his mother will also live with me and then started submitting his application.

You should always do a judgment and criminal background search before hiring any contractor; as a landlord I always do those checks on tenants to confirm they aren't shady - so the same applies to contractors. 

John,Please don't take offence, but that's a "Let Them Eat Cake", good in theory, but unrealistic response form someone who is Obviously not a Mortgage Broker and has never had to deal with the Builder's or Builder's Lenders relentless efforts to Coerce and Steer their client.I could be beating them in rate and in closing costs, but when their title company feeds the Builder's insider info as to what lender I'm using and then they come waiving $7,000 in builder credit to pay closing costs and/or home upgrades, client loyalty goes out the window!

Same question goes for applicants who pass the initial application phase but fail the criminal/credit/eviction screen.Thank you.Joe Butcher, Dallas TX

If the tenants are not violating criminal laws, then most often there is nothing you can do besides buying them out.

Filing a criminal theft complaint is free.
