I have heard some people setting up their heating cooling system to shutoff if a door or window is let open for a certain amount of time.You can also add a temperature offset to make it look like it is a few degrees cooler or warmer than actual since sometimes temp setting is a mental thing.

I have never seen walls painted this thickly.The kitchen cabinets have also been painted so thick (so many times) that the doors were pinching and scraping the paint near the hinges.The entire place was done in either satin or semi-gloss kitchen/bath type paint.

Especially if doors have to come off or even trim.

I also use the Schlage Camelot door locks, and a small iHome device that monitors temp/humidity/lumens and sound in the house. 

In the words of Master Yoda Do or Do Not there is no try.

I have great relationships with him, referring other clients, and he always shows me how to do it right way, and I already did multiple things by myself - making window screens, painting of 8 interior doors in 2 days, hardware for kitchen cabinets, replacing bathroom faucets etc.

It depends on a lender I just closed in a building 4 doors which two of them is store fronts and it was considered as a commercial by the  lender.

It would be difficult to keep up the ruse if you're living next door.

My husband and I flip houses and own two rental properties (4 doors plus 1 garage/storage rental)... still just getting started.

We have around 105 doors.
