Did you know that you can bank with some of the newer systems for property management?

I manage my own properties as do my clients; with the electronic resources for screening, rent collection, more - the ROI is greatly improved and you retain control of the property.Hope this helps.

Neither VRBO nor Airbnb are vetting guests, either.The best you can do is have some internal controls, such as minimum number of nights.

But, for instance, I sent them a notice of rent increase effective February 1 and needed them to confirm that they have accepted the new payment terms through our electronic payment system, and even after repeated notices, they are not responding.

Single family homes are exempt from rent control everywhere in the state.  

This is something their screening probably would have caught, or their system would have a legal procedure to deal with it.

Early testing of this new system indicates that it’s a pain to get access to.

It was the system that afforded this.

Like you I also have the RE license to keep some of the commissions and better control. 

I control all the money and pay all the subs directly.. that's how we got in trouble the first time GC not paying subs..
