Is it safe to build Tier 2 Links to your main site?

I am getting a good amount of Tier 2 links at an awesome price. Mainly I don't eye much to these links. Since, the links are good and coming from good sources. So, I am mulling regarding this.

My question is that, how will these type of links effect my main site? I will be setting them to several pages of mine but the majority will be directed towards the homepage and main landing page.
