Are there any advantages/disadvantages to selling to a builder?

[Chris L.]

I may be selling my property in Bergen county. It's an older one story that is in an area zoned for two story. I'm presently renting it out. I'm wondering what the pros and cons of selling to a builder would be and is there a time of year that is best to sell to a builder-profit wise. Would I make more money by not selling to a builder?  Most single stories are being knocked down and two stories built so I'm assuming that whoever buys the property will knock it down 

 Any input would be greatly appreciated.
