I bought humblemud house whats next buy¿

[Phil khajeets]

I need something cheap and cool only with gold though

[marstinson]

"Cheap" is going to be any of the inn rooms. The rooms in Ebonheart (Pact), Rosy Lion (Covenant) and Vuhkel Guard (Dominion) are free to toons from that alliance. The ones in Rimmen, Solitude, Vivec City, Leyawiin, Alinor, Gonfalon Bay are free to any toon, but it's one per toon. They're otherwise a few thousand gold each. They hold 30 regular furnishing items with ESO Plus or 15 without.

The houses in Skywatch, Sentinel, and Mournhold cost about 10-12K gold and hold about 100 furnishing items with ESO Plus or 50 without.

Humblemud is the cheapest of the small houses; the other eight are between 43K and 73K. Except for the Cyrodiilic Jungle House (Bandaari Trading Post in Malabar Tor), each requires that you complete the zone's story before you can buy them. They hold 200 furnishing items with ESO Plus or 100 without. They will hold all eight coffers/storage chests if you have ESO Plus, but will not if you don't.

There are a dozen or so medium houses and they're between about 200K gold and 350 gold. They hold 400 furnishing items with ESO Plus, but 200 without. They will hold all eight coffers/storage chests.

There are 14 large houses and they cost between about 750K and 1.3 million. They hold 600 furnishing items with ESO Plus and 300 without.

There are a half-dozen or so large manors. Hall of the Lunar Champion in Rimmen is free once you complete the Two Queens quest, but you must unlock two sections of it by completing Lair Of Maarselok and Sunspire (I think) on Normal difficulty. I believe Doomchar Plateau was also free, as in "no gold or crowns to get it," but you had to unlock it with stuff purchased from the Impressario with event tickets a couple of years ago. You might still be able to pick up some of those through guild traders, but you'll pay a lot of gold for those pieces if anyone is selling them. The other manors are a few million gold, but you must complete either an alliance story line (get the "Hero of the <alliance>" achievement), or Falkreath Hold and Bloodroot Forge on Veteran difficulty for the one in Craglorn, or the main story before they're available for purchase. The one in Coldharbour is the cheapest at 1M and is unlocked after completing the main story.

The rest cost Crowns and many are no longer available. They might appear again in the future, but you'll wait a while (I'm holding out for Jode's Embrace).

There are likely others that I'm overlooking/forgetting. As others have observed, fashion and/or furnishings are the true end-game.
