After doing the same kind of screening that I do out here in the Bay Area (No Smokers, No Pets, No Felonies, No Evictions) we still had many people that wanted the units.

On thanksgiving last year our tenants wanted to grill on the one we had and asked if we could get them propane...If it were me I would just fill it up but since they asked we went ahead and asked her brother to fill up the tank and bring it to them.We want to hand off the property management in the near future with someone that has a good team in place as we do not want to put unnecessary stress on our family but most of the people we interviewed managed from out of state which is the same thing we do.

I would also put some sort of outdoor grill with the unit. 

Also, comparing professional services to TurboTax is akin telling the restaurant manager that their chicken de bleu is not as moist as a grilled chicken from Walmart. 

Even won a smoker! 

DING  DING  DING   We have a winner Give the potential buyer a WOW to take away with them    Even better if you can put in a sliding window with a small simple inexpensive patio    I put in outdoor kitchens with fridge, cook top, gas BBQ grill, bar counter, sink and cement floor for not much over $1000 And 10 hours of my time. 

4) Are any in household Smokers?

I have had tenants tell me I could not discriminate against smokers, had no right to verify employment, no right to look at credit scores, no right to restrict countless things but most often it is pets, no right to do inspections even though it is clearly spelled out in the lease agreement that they signed. 

Because she was a smoker, the cobwebs were like yours except they were black and tarry.  

Perhaps place a couple gas grills in the common areas.
