I recently had an electrical panel that needed to be replaced that the inspector missed which ended up being $1,100.

I even added the electric bill showing them its in my name.  

It has separate gas, electric, two hot water heaters, etc. 

I will say for myself, I'm fine paying $X to install a faucet (for example), but when it is broken down into $A for travel, $B for labour...it bugs me-stupid, I know, but I'm being honest. 

Plumbing drains, water, and electrical were all VERY easy to run. 

I do know that some of the supply houses are great for lighting/electrical/plumbing/HVAC/etc.

Currently, there is a bug that is limiting the functionality of this feature but the team is busy resolving it. 

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.

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

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