I purchased two sets sets of indoor / outdoor units.

For example, a Smartthings hub with various sensors that would alert me immediately to water leaks, temperature extremes, frequency of furnace filter changes, and access gained to off-limit areas to name a few that come quickly to mind.The problem is that I really don't want the expense of providing internet & wifi, which would leave the renter's wifi as the only way to connect.  

It is now 200 plus 18 outdoor spots.

The contractor should have known better than to use thin rock that would move under stress of walking, expansion and contraction of temperature. 

The Heat Ordinance mandates that during cold weather months landlords supply heat to rental units or to any unit where owners do not have individual control of the heat.From September 15 through June 1, the temperature inside a rental residence is required to be at least 68 degrees from 8:30 AM to 10:30 PM, and at least 66 degrees from 10:30 PM to 8:30 AM.Landlords face fines of up to $500 per day, per violation, for each day they do not supply adequate heat.

I can see how your tenants would be especially happy about being able to control the temperature. 

It has a great layout and outdoor space, but it is small is square footage and has a tiny bedroom.

The biggest focus of the amenities will be the outdoor pool and property.

We bought our office in 2013 and have room for about 16-20 desk spaces and 1.5 acres of green space with agent vegetable gardens and outdoor areas to work or just recharge.

Another thing to consider is that windows are a major source of temperature loss and sun can heat up the property through the windows.
