Just need to adjust the way you perceive the market.For example, a $10,000 increase in NOI equates to a ~$140,000 increase in value in a 7% cap rate market but a $200,000 increase in a 5% cap rate market.

Do they perceive that they are great people and spent money on landscaping? 

Always turn the perceived weakness into a strength.

To date, no improvements have been done; however, due to the existing improvements, value and perceived value have been on the rise.

Eviction may indeed be the best option, but first verify if what you perceive is actually occurring.

It is only a perceived loss.

Maybe that's how I'm perceived at this point from the players that could actually bring me the deals I want.

Some rentals will drag you down in ways that a tenant or buyer cannot perceive value, like plumbing electric, etc.

The negative is that they can run straight to HUD and complain if a repair isn't done or even if they perceive it and HUD has to do a complaint inspection which can be a headache. 

Not fluffy income used for depreciation or some perceived tax benefit. real solid figures you can take to to bank.
