We recommend it be evaluated by a qualified electrical contractor or engineer at this time.KITCHEN / LAUNDRYThere is a stain from biological or fungal growth on the inside bottom of the kitchen sink cabinet.The kitchen GFCI outlets did not trip when tested with our tester(button on the outlet did work), and also tested as being ungrounded.There is no anti-tip bracket installed on the back of the stove to prevent tipping when the oven door is open. 

Depending on the class of this property get rid of that sprayer too just close off the 4th hole on the sink with cover plate.  

Check under sinks if you can, many times slow leaks occur there that go unreported.6.

His estimate was $1400 to fix a leaky sink, unclog a drain, and replace a faucet!

I think this would make sense in the long run for the rental property as it will extend the life of everything it touches like the Sink, faucets, showers, water heater, dishwasher, and Clothes washer while also providing clean drinking water in addition to the reverse osmosis drinking water system I already have installed.The main problem with this hardness level is that we get a major deposit buildup on all of these items, which will eventually clog up the faucets for tenants and lead to rusty shower enclosures that take forever to clean.In addition to this, it looks like we could likely have the salt added every couple of months by the property managers in addition to that it would allow for a quick inspection from them, and then also we would instead bill the cost of the service onto the ledger for the tenants.For reference, it does not look like the landlords in the area have water softeners.Thank you everyone for your input ahead of time.

If so what favorite paint colors do you all use, should I replace the sink or any fixtures?

Further to @Shawn Clark's point, if you don't have easy access, one way to tell if a property has been winterized is to look at the MLS listing photos.If there are small signs or tags that are taped on sinks, toilets, dishwashers, etc, those normally are signs stating the the water is off and that the property has been winterized.Around here, they're usually neon green or orange stickers with a few that are just white slips of paper. 

Example: Bathroom remodel (tub, sink, toilet and floor "laminated" $750).
