Batteries could go dead but if you are responsible you won't have an issue.

Ya be careful with innovation as well.Toyota now developing battery a battery that can last 1,000 miles.When it's commercialized Tesla is wiped out if they can't enhance their product.And the job loss would be significant enough LOL

I can have 19 codes, unlock or lock the door remotely, change codes remotely,  see the battery life, and get an email or text when the door is used.

How much do the registered brokers charger to bid on hudhomes? 

We need to keep our batteries charged and stay the course, right?

Same goes for things like batteries in smoke detectors. 

And, for batteries there is how much really nasty stuff in those?

So far thinking things like:- replacing air filters- testing and replacing batteries in smoke detectors and carbon monoxide alarms- carpet and floor cleaning and/or replacement - assessing for leaks and all working sinks, showers, toilets- wall repairs and painting - appliances are in working order- deep clean- change locks and battery -replace all lightbulbs inside and out- minor repairs- landscaping Anything I am missing?

We actually preferred the composting toilet because there were less chemical smells, etc.Both camps we stayed at had us bring our own water.Neither of the camp sites had electrical, but we could bring our own generator or battery system if we wanted.Mike
