Turnover/vacancy can certainly be a cash flow killer so youd have to compare what the total expected vacancy/turnover could cost vs. keeping the unit rented for less than its full potential to see which is most cost effective.

Anyway,  if your basics aren't working to get rid of then you can try rolling the mouse killer pellets in peanut butter to entice them to eat it.  

Or you'll hear one of them say, "Oh, Bruiser and Killer would just love this back yard."  

Some killer good deals and ability to scale along the way may even allow me to reach my goals sooner!  

If it’s a few months and the Fed keeps pumping Americans with money then stagflation will be the mid to long term killer.

Vacancy is the killer- I’d rather stick $3000 of granite and stainless in an apartment than be 4 months vacant.

I think @jose r. bucio is giving you killer advice. 

Acquire the most desirable properties you can which will 1) attract the high quality tenants, 2) increase the average length of stay which 3) minimizes turnover, ie the #1 cash-flow killer.

For me, in any kind of contract situation, this would be a deal killer. 

Now: the killer: are registers open?
