I moved on to purchase rentals that are clean BRRRRs and built a rental portfolio of over 7 figures.

I say that because you may have different inspectors calling out different items at each inspection for instance you may do a rough electrical inspection with one inspector and do a final with a different inspector that see's things a little differently forcing you to redo work already inspected.

Insurance probably sent an inspector who gave a ballpark repair cost in addition to the cost estimate the clean up company provided.I'm assuming you used the clean up mitigation company the insurance suggested, who may not be your best choice.Get another estimate to return the property to full glory, cost for paint, glue, dumpsters, every nitty gritty drywall screw, plus putting your tenant in like kind housing.

I think a ReafCo filter would clean up half of the issues.

Instant water heaters take up less space and come in electric or gas versions.

When we do rent it out, we plan to add a flat fee for the included electric.

I have seen properties convert the radiant heat system to electric board heating style during remodels.

I have 3 bedroom 2 bath residential home in a nice area on a nice block which all the neighbors have well kept up and clean homes.

Otherwise, the renters could be bitcoin mining or driving 2-3 electric cars and you’re paying for everything. 

No personal experience here but here's a helpful reference from someone who wrote a blog about different aspects of a 2 flat remodel in Chicago Scroll to "Two-flat journal 6: How to make an all-electric house" - - speaks a little about heat pumps and cost In the HVAC section.
