Is there such a CMS or plugin for Wordpress to create a website?

Question

CMS

Please advise a CMS (easy to learn) or a plugin for Wordpress (since I am familiar with WordPress) in order to create a complex site, for example, for buying and selling real estate and so that users can register on the site. For example, one user could add a picture and description to a certain catalog, another user could find the necessary information in a catalog search. To have a forum or a way to connect it. Well, and so on. I hope the point is clear.
Example: something like this . It is clear that there is no CMS here (although hell knows), the site was probably made manually. Anyway, there is an engine to do something like that.

Answer 1

the site was made manually by 3 programmers since 97.
it seems to still work on 3 puff under Windows) (although something may have changed since then)
on your question google realty cms , google realty wordpress plugin theme
or just a directory of articles can be represented as your ads

Answer 2

Search themeforest.net/search?utf8=%E2%9C%93&term=realty&...

Answer 3

Wordpress seems to imply the registration of users with rights to add content. It is enough to change the role of the new user in the general settings. And you can make your own add-on forms.
Another issue is the scale of the project. Portals of this level are made on their own cms, otherwise you will face a number of restrictions.
