What made you interested in investing in this type of deal?

This depends on the lender and what is charged in the orig fee.

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.

Devin,Thank you so much for the info, I will look into this.

There are a lot of great resources on BiggerPockets, whether you are just getting started or have 30 rentals under your belt.If you have specific interests or questions, find the appropriate forum category to read what others are saying or ask questions. 

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?
