Ag well + domestic well, or just one well and does that require softener (component inspection and well inspection). 

This strategy, however, should soften the blow, allowing your move to be a smart financial step and add a personal touch to your investment journey.

Real estate markets change slowly over time, and while it's possible you see prices soften somewhere a little for a couple years, look at the big picture. 

It's a great way for the land owner to draw cash out of their land over a long time, softening their tax impact.

I'm not that professional but I think a whole house filter would filter particulates like dirt but not chlorine. for chlorine you might need a reverse osmosis system for a specific drinking water tap to eliminate the taste as it's not practical or efficient to put an RO on the whole house supply. if skin issues from bathing are a problem you might need a softener. sometimes when kids have eczema doctors actually prescribe "bleach baths" where a small amount of chlorine bleach is added to the bath water. also many of the water treatment systems can be rented so maybe just rent it while they are there. regardless, proceed with data. water test, pediatrician diagnosis (if it's legal to ask for, no clue), and a system that is right for the application. sounds like the tenant is willing to help out which is awesome.

Some of the work and tanks have been covered by warranty.We have a Rayne water softener installed and they are coming out in a couple of weeks to test the water.

Plus I just spent 4K on the AC and did some other repairs (about 2 k total a couple of months ago)... her one year lease will end in the beginning of May, so couple of weeks ago she told me that I should lower the rent by $300 per month "to persuade her to stay" because she said the rents have softened.

IF that was the case then we would not have homes sitting on markets and prices declining/softening.

The softening in multifamily rents, in some markets, is largely attributed to the supply of new luxury product coming on the market.

Nationally, rents are even finally softening.
