The lender deemed the master policy provided by the condo association to be sufficient for their purposes.

In addition to ensuring that the room is built to the proper load bearing capacity as @Mike Reynolds mentioned, you should also keep in mind that you need a second egress point, such as an egress window, for any habitable room especially if it is designed for sleeping purposes.

And presented in very complicated way, hard to bring them to an apple to apple comparisson.One way to mitigate the lack of a net metering agreement is with a battery system (see Tesla Powerwall) - a very expensive way to become a truly self-sufficient energy producer (basically you become your own power plant), which rarely makes financial sense unless in a region with frequent power loss or in an off-grid scenario.

If I was younger and needed less sleep it would be even better.

I've never really had a problem with that, but if it makes you feel safer and sleep better at night, I say go for it!

When I see rust eating at welds like this I wonder how much of the problem comes from the management company (Rust never sleeps).A maintenance tech scheduled for some time with a wire brush and some Rustoleum could have saved this expensive cement tread stairway.Now it a welder (if it's salvageable) and the Rustolem, plus the cost to construct that ugly unpainted wood bridging system, and tear it down.And despite all of the drama that's going on, Mrs Kitty still has her favorite spot in the shade next to her food and water--a natural foe to garbage rats.
