I also configure thermostats, timers for lights, heating and fountains.

Does anyone offer this type of thermostat for their tenants to control?  

If you needed to move for work (or another reason), you could live in it for less than 12-months.In our programme here in Canada, you can have only one insured mortgage at a time (legally) ... check out the details of FHA or other programmes available to you.Most such programmes are aimed at owner occupants and that is how the rules are structured.

I've had thermostats successfully repaired, and I just replaced the motherboard in my own fancy Samsung.

We send someone in 4-6 times per year to change filters (furnace and HRV), batteries (thermostats, detectors, etc).

I'm a computer programmer by trade but have always been handy.

Since she is a computer programmer.  

Also changed furnace filters, and new batteries in the thermostat every other year.

Once you know the features you want, a decent website programmer should be able to create your site for a a few thousand dollars (price may vary depending if you are satisfied with a template or want the site created from scratch).
