There are some post on other forum that it is risky to buy High PR Domain, because the PR of the domain will drop after the transfer of the ownership..

 

How true is this?.

Google Pagerank takes a long time to build up, and is based upon many factors (the true algorithm isn't actually known).

 

Some important things are the content of the domain, amount of backlinks, age of the domain, etc. If you buy up the domain and completely change the content and start losing backlinks as a result, obviously this will have been a poor investment.

 

The point is that the transfer of ownership won't cause the decrease in PR, but rather a change in the content will. If you're buying a high PR domain, make sure that you're getting the content as well.
