The risk is huge that a new domain you have bought will be penalized by Google in the beginning and put in the so called sandbox if if you build links to the domain to quick.

What you need to do to avoid the sandbox, and getting listed way back in the SERPS, is to as quick as possible put some relatade content on the site. Just some text including the keywords your site is about.

By doing this the search engine can easier identify you site and when you are ready to start your project your site probably has enough trust to avoid the sandbox.

I do this with all my new domains and it certainly helps alot. Try it yourself. This makes the SEO work much easier.
