I would ask the PM to reduce their compensation for the year to offset their failure to execute your documented instructions. 

My opinion is to have 6 months, or min of $5k per property up to 3 properties before reducing that if the home is newer, or in good condition. 

Documents reduce debates.  

I use instant booking which reduces time.  

This takes a little more work, but it's the most fair and reduces the likelihood of tenants that squander utilities.If you choose #2 or #3, there are considerations:Start with an average.

Quote from @Chris Bergeron: I would let her leave quickly, but I would require her to allow me to market the property immediately to reduce the impact to my income.

Very often they are able to have reduced insurance rates often a 200-300/year for liability only. 

If you have a good sit down with tenants before/during the lease signing and explain everything upfront, you will reduce the risk of it coming back to bite you in the *** and they will be conscious of it.

At a reduced price and in bulk, a decreased rent may still work out to the margins needed to be profitable.

So reduce you buying price by $5,000 to compensate for it.
