@Dave MillsSimple question: what’s the temperature in the house?

Now that that's out of the way...There are tons of economic micro-climates and each city will have a different investment 'temperature' so it would be sensible to narrow it down.

Our average temperatures are June - 75, July - 77, August - 76, September - 71.  

I did not see this forum before writing the lease and did not include that it has to be at a set temperature. 

However it does take a lot longer to move the temperature of the space and there is a higher initial system cost than electric.

What is the temperature of your private lenders?

No one turns on the central heater at home so should I install a smart thermostat to keep the house at a consistent temperature?

Welcome Melissa, Good to hear you are enjoying the Palm Springs of Washington state, without the 110° temperatures.  

Old thread, I know....but the answer depends primarily on the type of flooring:Flooring that floats above the floor… Such as interlocking vinyl planks, Should NEVER go under the cabinets… Doing so will cause the floor to Buckle (and/or break the locking system) because that type of flooring needs to expand and contract as temperature changes.Flooring that is glued to the floor permanently,  can go under the cabinets without any issue… But realize that you may STILL  very well want to replace the floor but sooner than you will want to replace the cabinets… So you could go either way when it comes to glued down flooring. 

And in my house, which is maintained temperature and humidity.
