You might not have equipped the house yet. Deeds need to be equipped, just like weapons or pets. Switch to the housing tab by opening your backpack, then clicking the icon in the upper right to go to the Ship Equipment menu, and again to switch to the housing items menu. So far, housing deeds have always been in the first slot on this page, but there is a button at the top that will display just your housing deeds. (It's on the left edge of the row of button, and looks like a house.) Double click the icon for your Buccaneer's Den, or select it and then click the Equip icon at the bottom of the screen. Once it's equipped, clicking the Home icon should take you to the den.

Also, you still have your bunkhouse room in Avery's court. You can visit that one by using the Skull Island button and going in the door to the bunkhouse there, or by unequipping your deed, or (I think) by using the Home button again when you're already inside your bigger house. (That's how Wizard101 does it, at least.) However, using the Home button twice like that might prevent you from using the "Go Back" button to return to where you were - I haven't tried this myself yet, so I'm not entirely sure what happens.

thanks i will try that because i spent 5,000 crowns on the aztecasor pack and got mostly house items and things to sell for gold the highest thing was a fish that went for 975 gold so i am happy to try and get the den
