Are you using apple pie scented candles to set the mood?

I have met/known over a thousand Realtors and a few hundred appraisers, on the average, I'd have to say a Realtor does not hold a candle to a state approved fee appraiser in any professional ethical issue as there are many more bad Realtors than Appraisers (there are bad apples in all professions) and the very best BPO performed by one with only education and experience gained as a Realtor(since these are relatively new in the industry) won't come close to the quality of work of a Certified Apprasier.

Well, that would avoid the need for scented candles in your staging.

For example, if someone is burning a candle in their house in a way that is unsafe and can lead to a fire, the right thing to do is tell them.

Scented candles work too, as well as a couple of potted (fake) plants on the countertops.

Such as: freezing pipes in the winter, overheating in the summer, tenant actions that endanger your property (such as cooking with BBQs indoors, using candles for light, use of extension cords from one dwelling to another and overloading of electrical circuits), humidity build up, garbage overflow and vermin that follow that, etc.

Should you always stay at home eating beans and rice and use candles and have no cable or furniture?

never. see the pics on my website.... put some towels,  candles,  seasonal signs,  a smelly filter in the furnace and drapes.  

no seriously by candle light, I haven't had the contractor come over and install the fusebox yet..."

Other than that, candles and stove heat are likely in your future.
