If I were to take an educated guess, it sounds like a company that is looking for people to do digital grunt work (ie, going through tax records to find properties, setting up mailings, paperwork, etc).

Is it worth it to have it all replaced just so I don't have to have them dig it up again in the future?

I have accounts set up at my local hardware store so my handyman can purchase what he needs.

With rapid advancements in prop tech and a growing trend towards digitizing our daily lives, I am convinced that in-person tours and leasing will eventually become a thing of the past.  

Given that I do not want to deal with those creative tenants that may not pay eventually and have to go through an eviction, so they're free lawyers or tenant advocates will advice them to use and make a digital payment, which would make things a lot worse in trying to reimburse them since if you receive or accept payment it automatically usually voids your active notice or eviction case and you have to start over.

I have heard about this 9 digit number but I thought it was called a CPN number.

No fees after you purchase the hardware/software.

My input as a digital marketer is that the half-life of an email is generally extremely short, like an hour or less.

The only 2 solutions for me was too dig it up and take roots out and re-angle pipe  or he said instead of doing a clean out every so many years I would have to do one on that building every 6 to 12 months at a 100 bucks a time. 

Not sure how viable they are in many situations but interesting to keep in mind regardless.Since I deal with HML regularly I look at a 3-4% up front fee as standard and if I can get it with out double digit interest and secured by 1 or more properties then I will take that all the time!
