What customer service programs do you have in place?

You would use custom soft-close cabinets in a more expensive place and stock normal-close cabinets for an inexpensive place.

Customer service has been increasingly more difficult to deal with.

Is there something I can use to customize and send 3 day notice, lease violations, etc?

Unless you are their only customer, I think it seems presumptuous of you to expect that they've got guys sitting around just waiting for your property so they can get it done immediately. 19 days from the day they got the keys to listing doesn't sound that bad to me.

I always get a live person open the phone when I call their customer service line and the ladies that I speak with are very helpful.  

Customers that I had up there with apartments, generally owned them for a long time, inherited from the family, paid cash etc. and do well from that, but will never sell their cashcow at a steep discount. 

Although Hemlane is an acceptable software for 50 units it's clear it won't be a long-term answer since it lacks some customization and automation abilities.  

*Adding high efficiency water heater & furnace so we didn't have a chase in the kitchen *Custom bar and hand crafted bar top in the basement - we could have gone with something pre-made or not have done a bar down there at all - just a cool feature we added cause it added value/storage to the space  *Upgraded plank flooring in the basement - it had a water proof sealant and was about $2+ more per sq foot than the cheaper stuff *Demoed walls that would have closed off the kitchen - requiring electrical movement *Added a sprinkler system/new sod - we had a sewer pipe we replaced in the yard, so instead of just patching up what we had to, we made the backyard brand new Again, we did make a profit so in no way was this a sour deal for us, just added a lot of really unique personal touches as well as going the extra mile in certain areas.  

If so you can do both and use the cashflow from the snow business to invest in more properties.The main thing to keep in mind is this will not save you money directly on your existing properties as you want to charge market rates for your properties just like you would for any other customers.
