Make sure you factor in long lead time items in your build (electrical panels have a 14-week lead time right now). 

I have a large MF lot I am looking to put a modular pre-fab or panelized 5-10 unit building on due to lack of available labor...builders are all busy.

Got an inspection report done and it noted a few panels that might have needed replacing (nothing to serious), but once we started opening things up, we realized minor patchwork won't work.

Quotes to add new meter and panel from excel are a lot not to mention Xcel and Denver permits are months behind and I don’t want to wait that long.Would sub metering be a simpler solution?

It'd be like if I told you I was thinking about buying a hybrid car to save on gas and your counterargument was that I shouldn't do it, because if I had a solar powered jetpack I wouldn't need to pay for gas at all.

I like when the tenant puts a check in the electrical panel box and landlord picks it up on the first.

my wife just sold a property for one of our new construction buyers.this client also got talked into buying the property without a home inspection.so she had to put a new roof on it new Hvac upgrade electrical panel and a plumbing issue.the agent that sold it to her is known to us and he is a slime ball no question.bottom line your the client you dictate what you are going to do or not do never let the agent tell you what to do.. 

One example I upgraded a 100 amp panel to a 200 amp panel. 

For example, a house built in 1920 with new HVAC, new roof, and a new electrical panel might be a better buy than a house built in 1950 with original systems.For the gardener services, why have a line item for it if you are handling it?

Run  some 220V wiring in pvc underground (licensed electrician) to power a good pump if you have space/amperage reserve in your electrical panel. 220V requires less current to run than a 120V for the same power, so it's more efficient.This guy has a lot of good videos on diy yard drainage systems.
