As a very generous estimate in my favor, I'm guessing the water heater, ac unit, fridge, dishwasher, and microwave will all need to be replaced in 10 years.

I had to replace fridge, fix 3 outlets, a few other things.  

Buy a new fridge and it could have been much worse, there could have been holes in every wall and the copper could have been stripped.

Remove the "complicated drain" and let them use a rubber stopper, no programable thermostats, no fancy ceiling fans with remotes/wifi, no fridges with water/icemakers, etc.

I like that people aren't stupid enough to take a saw to it to try and fit their brand new oversized fridge....I like that it can't be burned when someone puts a a pan with the flaming remains of the thanksgiving turkey on it...I like that it doesn't soak up stains when the kids spill koolaid on it.Lol.

One stole a fridge on the way out.

I purchased them at Lowes on sale and the fridge was a scratch and dent special (and they even replaced the missing part for free!). 

No ice maker on the fridge as it breaks down and the line in back tends to leak and cause damage.No legal advice

Right now at our house we have a big wall cavity open around our fridge because we haven’t decided how to do it and have learned to live without it finished. if I were you I would run the numbers on buying a fixer.

Its the stove the city cracks down on, as you can work around this by installing a wet bar which can include a sink and fridge,does not include a stove, built-in microwave, dishwasher, a garbage disposal, or a gas line.With the second kitchen your house would act more like a duplex with two units rather than a house with roommates, in practice the pwnership experience is pretty different when you have a separate entrance and separate dwelling units.
