Next update - new water softener. Any input on the value of adding a reverse osmosis system?

6. My plumber had me drop off water samples from an inside tap, and an outside tap

I have no idea how old this water softener is, but the test results showed, at this point, it is pretty useless. The old furnace and well pump and tank were about 32 years old! I think the water heater wasn't much newer.

I've used this plumbing place for my new furnace/ac and water heater, and it came recommended by my cousin, who used them for EVERY plumbing need and highly recommended them, so I'm confident they will give me the best price, possible.

All of my replacement/upgrade decisions have been based on what will make this house easier to sell, for a good price, either by me or my estate. A well is a big selling point for some, and not so much for others, so I'm leaning towards the reverse osmosis unit as a 'mitigating selling point', if it isn't ridiculously expensive.

Next is painting and then pulling out the carpets and getting the oak flooring up to snuff. It's been covered by carpet since it was installed, and from the little we've seen by pulling back carpet, it is in pristine condition.

Who knows, I might get this Brady Bunch style era house upgraded and so beautiful (shag carpeting in the den and bedrooms) I'll spend the end of my days here.
