Since she is a computer programmer she can work at home.She still gets paid as a full time worker.  

Lock the thermostat so tenants do not have ability to change temp settings as well.

From their work, you could go to Excel and run your VBA, or just have your programmer generate the report in Excel format for you.If you have the programming done, do the post processing in Excel, it's just easier to make that happen using VBA or some sorting.Good Luck!

I am a computer programmer so I am good with computers and making website, which can definitely lead to consulting business.  

Luckily she is a computer programmer and makes a decent salary and is only expected to come to the office for a 1/2 day and do the rest from home.I was lucky that I collapsed in the evening and my wife was there and called an ambulance and I was in the hospital for 30 days and I do not remember any of that.

My wife, a computer programmer, makes enough money to support us all without going into long term debt.  

Also what's the best cheapest digital thermostat I can buy?

As for the furnace you are best to lock the thermostat.

Since my wife is a computer programmer she is making pretty decent money.  

Thank God that she is a computer programmer and makes a decent salary.
