While we don't have a ton of moisture issues here with basements, we have expanding soil issues and have to build floating walls in basements. 

A sub contractor I spoke with recently told me that some homes have issues with moisture from the ground.

LVP has the upper hand when it comes to moisture, but in my experience I've found that it scratches easier than laminate.

Thanks John, the LVP that you buy, if it has the underlayment included (moisture barrier) is that enough for you and your basements or do you put a moisture barrier anyway?

Appears that he redone the ceiling and moisture damage in baseboards).

There is also some moisture stains in the roof.Wires on the outside of the house seems to be defective.

If you have made any effort to reasonable air seal the building envelope, then you need the range hood to extract stale air and humidity as a regular air exchanger will not typically be able to adapt to accommodate cooking.Even if your house is not tight, it is still appropriate to properly vent the cook top to prevent moisture damage and grease build-up on the ceiling above.

Also thinking of buying moisture meter to check reading.

The carpet is so stain resistant that a Sharpie permanent marker cannot stain it; also bleach will not damage it.We also use stain guard pad with the carpet that will not allow liquids, and pet urine to penetrate into the pad or flooring below.When tenants moved out, we require them to have the carpets professionally cleaned.

Could also be the damage you noticed on the roof while looking at it from the backyard or moisture you saw under the kitchen sink that "could" cost a lot of money to repair.
