They keep the property in a condition that it appears owner occupied with a pride of ownership.  

Yesterday I went to the home to see the condition, there was no car on the driveway… I opened the main door to peep inside…looks like they still have lot of their stuff inside and I can smell bad odor; I just closed the door and returned back.

You’re kinda stuck, as you can’t clearly “evict” the tenant…maybe only if there were hazardous conditions.

According to the National Association of Realtors' Code of Ethics, realtors must avoid concealment of pertinent facts and should not misrepresent the condition of the property.

Found a really good deal on a 2 bed 1 bath older home in pretty decent condition.

We price the properties according to their current condition.

In this scenario, you have to make sure the house conforms to VA guidelines in regards to its condition when you purchase. 

Most properties in liveable or renovated condition receive multiple offers.

It was a fairly nice house, somewhat dated but in good condition. 

For a tenant to receive a reduction, the landlord must have actual or constructive notice of the existence of the defective condition."
