Should a home seller get an Independent appraisal?

[Mark Belenky]

I've just renovated my primary residence and am about to put it on the market and I'm wondering if it would be worth getting an Independent appraisal done.  

The reasons:

I live in 1 of the 18 unit townhomes located in Keyport, NJ and these units are quite unique.  There aren't any true comparables within this or nearby locations.  Throughout the years these units ranged in price from $255k - $292 and now with real estate prices at a high, I don't want to leave too much money on the table however, I want to sell this home quickly.

The doubts:

I don't want to waste any more money than I already have renovating the home.
