For example, if you can prevent the nightmare tenant, you avoid--well-- nightmares (like real ones, where you lose sleep or wake up worried how the eviction will play out or toss and turn wondering if the non-paying tenants are trashing your place; you drift off imagining them doing nefarious things under dim lamps with bunson burners and beakers amid a pile of trash surrounded by half feral pit bulls resting on dirty mattresses)... 

While there I went into the closet to reset the beaker, I open the door, leaned in to reset a breaker and was done.

Let's talk about double tapped beakers.

We have always gone to 200 amp but then again 300 amp would definitely be a plus for a geothermal configuration, or the 240v 3x50amp breakers for a LARGE on-demand HW system or maybe the HVAC of a discreet 'grow' facility :) Admittedly the extra amps would adequately supply the future ADU BUT assuming it's allowed I would be inclined to install a separate meter/feed for that.The $3500 sounds reasonable...the last 200 amp upgrade I did myself ran about $800 in materials as those 'code required' AFCI beakers will 'break' you $$$.

.- Supply and Wire new 100 Amp Panels with New Beakers for each unit and (1) House Panel with New Breakers- Rewire all units with new wiringI spoke to one electrician, and the amount he estimated is staggering.Anybody experienced could help me guide with ballpark numbers?

the electrical is waay under-powered just 2 beakers per unit..

Tell the tenant to unplug all the electronic applications connecting to this circuit beaker.

This is bogus as far as I'm concerned, unless all The breakers are GFI beakers.

Trying to decide if that's a deal beaker...
