The appraisal should be order by the lender and is a reflection of the market value of the home. A licensed appraiser is well trained to spot those items which can be detrimental to the value of your new home. there is no need to "forward information" which may in anyway be construed as influencing the appraiser.
In the future, please run these questions by your Realtor before asking one party to share information with another.
Hope that helps.
These are two different parts of your home buying experience.
The appraiser appraises the property for the value for the lender, the inspector is the one that finds any defects for you.
