Recent Home Sale Values Appraisal Value During Refinance Would Effect Future Sale Price Of The Home?

Appraisal value during refinance would effect future sale price of the home? - recent home sale values

If you sell my mortgage refinance with a lower valuation is below the real price of housing purchase, not if I will influence at home in the future?
I bought the house about 15 months, 265K, and now I am trying to refinance the house, apparently evaluator lender has less value 15K. I doubt, not knowing if they come with a good value.

I am sure that my neighborhood does not reduce value because some of the recent events, such as selling my house in the same area has sold slightly more than 10% of the purchase price, and a few "friends who have the same plan to refinance my house (my lender) provided a best value evaluator price.So his fault that the medical expert for the home.

My question is: If I go by offering more money to refinance, I am a little nervous about the future price of my house.
It will have an impact on the selling price for my house with the decline of the estimated value?
