Playing House achievement in The Witcher 3: Wild Hunt

This achievement is a very costly achievement and you need a total of 14,000 crowns (standard currency) to complete it as below. Note: this achievement appears to be bugged for multiple people. To fix, reset your xbox then load a previous save (autosave/checkpoint) from partway through buying, complete as normal and you should be ok.

Firstly, to gain Corvo Bianco you must defeat the rock monster and meet the Duchess. She will give it to you in a cutscene. After the cutscene you will be on your horse, you can either ignore that quest, or just keep going until you have finished it.

Once you are free to, go to Corvo Bianco (where you defeated the Bruxa, there is a green chest on the map) and head to the entrance of the main house. A cutscene will start and you must follow the quest "No Place Like Home". You will follow your Majordomo around the area until finally you will end up inside the house and can purchase renovations from your Majordomo after talking to him.

This is what I did to unlock the achievement:

Begin by purchasing the general house upgrade for 5000 crowns, then buy the grindstone and the armouring table under the grounds upgrades for 1000 crowns each. Then wait three days using meditation.

Now talk to him again and under the house upgrades buy the bed for 1000 crowns, the weapon rack and armour stand for 500 crowns each, and finally the guest room upgrade for 1000 crowns. Now under the grounds upgrades buy the stable upgrade and herbs for the garden for 2000 crowns each. Wait two days and talk to the Majordomo again for the achievement.

Total crowns spent: 14,000. If you need more money then save and go to the tournament grounds just south of your estate and sell as much as you need to the armoursmith and weaponsmith, then just reload once you have the achievement.

Thanks to HaloMonkey3009 for finding the bug fix.
