I have purchased I preowned domain name. The old website is still indexed in google with the old content of the previous owner. I'm planning to publish a new website using the domain but in the next months. 

What should I do to restore the state of the domain and start from a clean state? Is there a checklist on what should I do after buying a preowned domain with the intention to provide a different content. Is there a way to tell Google to forget the website and clear all history and treat the domain name as a new one ? What is the best practice to keep the domain without content (while building the website) without harming the SEO (since google already knows the domain so it will try to index the empty website). Here is what I have done already:

* Changed the name-servers ns1 and ns2 to my hosting and put a empty index.html file
* Added the domain to Google search console
