Every month is good to check smoke/carbon monoxide detectors and replace air filters.

I use the standard California Association of REALTORS package, which is 6 pages plus another 2 pages for lead paint, smoke detector, carbon monoxide detector and water heater disclosures.

Quote from @John Carbone: Quote from @Collin H.: Dynamic pricing is critical to achieving maximum revenues.  

The price of these devices has really come down and they are as affordable as the old carbon filament lamps once were.

This is very market dependent, in California where there are additional and significant economic benefits to having a small carbon footprint, the appraised values to seem significantly higher when you have panels.

I disagree with @Dennis M. about smoke and carbon monoxide detectors.
