I'm seeing that there is a strong resistance in certain neighborhoods (maybe rightfully so if there have been poorly overseen party houses in the neighborhood). 

I'm resisting articulating all the reasons why their email was out of line and that the increase was justified, but I am sure that will come across and defensive.I am now thinking this might be a case of "keyboard cowboy" syndrome on their part.

That means seven bazzilionty circuits in the kitchen, one outlet on every wall in the bedrooms that is at least 3' long and one every 6' on each wall, tamper-resistant outlets where needed, GCFI where needed, etc.

I've hit some resistance finding the right team members as far as contractors, lenders, and home inspectors go.

My significant other is pretty resistant to 'downgrading' to another duplex/multi-unit for 12 months, which makes things a little more complex...

When you take out full height walls you reduce the structure's resistance to wind and earthquake forces. 

Some must have heat packs for supplemental resistance heat....
