I'm thinking a pure white or perhaps an alabaster white.

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.

Or are you purely looking to go the conventional route only? 

They bought 72 houses in six months at the age of 23 and now drive their Lamborghini to their castle where they party with P-Diddy and drink champagne all day.

If not, would anyone be interested in connecting over a drink or coffee on 10/27 or 10/28?

Thought it could be of huge value as I made this purely from needing it myself when I did my first fix and flip project.

And I don't feel like I'm "missing out" on anything, because (a) I'm still close to BK and NYC by car or public transport and (b) there are plenty of things to do and places to eat and drink across the river. 

You know, I remember when I was just getting started myself... it can feel like trying to drink from a firehose with all the information out there, but places like Bigger Pockets really make the journey more manageable.

At some point, when pure cash flow is more important, then looking at a longer buy and hold strategy may make sense.

@Pradeep Roy are you purely wanting appreciation?
