Another thing you can do when you receive one of these texts is immediately report them as spam to your cellular carrier. 

I have around $1.5M in Mortgage debt locked at below 3% 30 year fixed. i have stable income from a big cellular company in San company so i have stocks.

If you're in a very competitive market you may want to get the house staged (filled with furniture) for marketing purposes.If you must list it in such a way as to disclose the address (for example you list it with an agent as a rental) please spend the extra $15-20 bucks to install a simplisafe alarm system: this is an inexpensive alarm system that works over 3G cellular networks.

The $1,000 estimate for the equipment isn't unreasonable, but my concern is that this system requires internet/cellular service to transmit data to the provider.  

Some security systems will operate over cellular but there is a monthly fee.

This is what I'm thinking:service setup through Guardian and they will do the bilingpulse output meters installed at streetgateway system that has both cell and wifi (assuming buyers have wifi, they can save $10 per month by not using cellular)gateway has app built in for owners to connect and see usage via mobile appwater bill paid by HOA and the owners pay the HOA for their individual billsMy goal is to make this as seamless and painless for the buyers. 

There is not internet in the house, so the system has to be cellular with remote monitoring.

Owing money to cellular phone companies, student loan debt, and medical debt is common.

I have never used Simplysafe, but most security systems use cellular and the cost of service is part of their monitoring fee.
