(Lifted from the original mod description)

When you get the 'Deed to Goldenglow Estate' from Gulum-Ei (dead or alive), you actually become the estate's owner. Then you can keep it and get a monthly income, or sell it to Maven for a hefty sum. This is not intended to make Goldenglow the umpteenth player home, it's just for immersion's sake. ESP-FE

I'll begin with what this is not: it isn't another hyper-stylish, all-gadgets player home.
Personally I find this 'new player home' galore a little overwhelming, get them all and most of Skyrim is yours, you could just evict the dragons, no need to kill them.
That said, this is a small lore-friendly immersion mod.
You conquered an estate owned by a runaway guild member, you got the deed to it from a frightened Argonian pleading for his life, it's rightly yours now.
You can sleep in it, stroll around proudly, be greeted by the workers, get an income, store stuff, sell it.


Ownership

• Aringoth and possible surviving mercenaries are removed.
• All the items are yours.
• The bed allows for a good rest.
• The interior containers are set to no-respawn for safe storage.
• The beehives are repaired, a few farmers and beekeepers (and four chickens!) are working at the estate; they have a daily schedule and a bed to sleep in (not the chickens, I'm afraid).
• You get a copy of the keys, in case you're still missing some.
• You find the estate's monthly revenues in a strongbox inside the main bedroom (25,000/year, more or less); if you don't retrieve them, they keep accumulating.
• Once the "Scoundrel's Folly" quest is completed, you can bring the deed to Maven and sell the Estate for a whopping 60,000 gold; you lose the ownership, the keys, and the monthly income.
  

How to start
Soon after leaving Brinewater Grotto with your deed (if you had already got it before installing this, pick it up again and bring it along for a while) you get the traditional "visit your new property" miscellaneous quest objective.
Going there completes the quest, that's all.


Compatibility note
If you have mods with book edits (eg. Book Covers), the deed could still be wrongly named "Goldenglow Bill of Sale" instead of "Deed to Goldenglow Estate" [I've also keyworded it 'not sellable' because I often sell important stuff by mistake].
Although the mod would work in any case, I suggest to load this one after those kinds of mods.

Note: If there are any bugs or issues with the mod, be sure to let me know. I am not the original mod author, however, I will do what I can to fix these issues if possible. Please, however, make sure it is not a compatibility issue between mods before posting a bug! Any mods editing Goldenglow Estate will probably conflict with this mod (i.e. Owning Goldenglow Estate).

Thanks to tarlazo for creating an amazing mod which I have wanted since my first ever Skyrim playthrough!
