Most were 2/1s.I want to close the back off and make a nice outdoor area.

Connecticut housing judges usually frown on this kind of behavior from tenants.Be careful, if your tenant's heat has gone out AND the temperature in the unit has dropped below a certain temperature (usually 65℉) the property could theoretically be declared uninhabitable.

Would you rather be home based in the Bay Area with tons of things to do nearby, good weather, lots of nature, etc. or someplace with little culture, extreme temperatures, bland immediate environment, etc., etc.

They were thrilled to have him and not deal with copperhead snakes infesting the outdoor space near the house.  

Also, I now leave a bottle of that indoor/outdoor safe-for-kids-and-pets insect spray that's supposed to stop bugs for months but usually needs more frequent applications, and tell them they can spray around the perimeter if they want to when it starts getting warm outside and the bugs start showing up and that it should last them all season.  

I want to mention from your last posting if it has no outdoor storage you want to think about where they put the lawn mower, bikes etc. 

-outdoor grade carpet (if you have a flood, you just take it out, clean, hose it off, dry, set back)-bamboo (you want tough; you want to control humidity, you want low/no levels of formaldehyde etc etc, you want good installers and product on the market for at least 3 years)-bricks/pavers-plywood (4x4' or 2'x2' or planks) @Michaela G. / @MichaelaATL-tongue-and-groove OSB refinished as squares/planks ("looks like cork") @Cristian Morentcy-luck: you lift the shaggy-get-a-mower carpet and there's old growth wood under it :-PP.S. sorry, my google fu is low today so not links

If you feel that strongly, be sure to say no visiting cats, no feeding outdoor cats, etc.

I've got a neighbor who leaves two dogs outdoors and I can tell you their work schedule to the minute from when the noise stops. 

In a great and perfect world your A/C would be zoned so you can set the temperatures for each floor, the norm however is that the thermostat is downstairs so the A/C turns off before it cools the upstairs.
