The best bang for buck are those laptops with a 256gb SSD drive and long battery life. 

The first property we had inspected is in great shape and we were asked to fix a handrail and replace a battery in a smoke detector( simple $150 charge for the inspection and $20 for me to fix).

My guess is they were in a hurry and skipped the scan or they had a bad battery or some reason it didn't get picked up.

Calling Florida Power and Light, told me I am caller number 475, please wait patiently, and my cell phone had 30% battery left, with no way to recharge. 

I replaced the batteries at the controller near the bedroom and it worked.

This is only a 4-plex but the CE officer told me that the big complexes will send someone through a few days before to change the smoke detector batteries and make sure they work but by the time the inspector comes, 25% have been removed by the tenants. 

They battery went out on the garage remote and they told me the garage door was broken. 

Have you checked the batteries ?

At the same time , not only does the 90 day challenge put a battery in my back, but a mentor falls out of the sky.

It's true that Battery Park and Barton Heights are dramatically improving.
