I'm really enjoying this aspect of homestead, but if you're an enthusiast, there's a substantial cost in terms of item budget, crowns, and gold. I got Mournoth specifically for the architecture, big yard, and reasonable price, but I'm not even close to finished with my landscaping and I'm already over 50% of my total item budget (and the interior is completely empty). Most of the small plants are only available via crowns - they're cheap, but it adds up. Nice trees can be purchased with crowns (not cheap) or in-game, but they run 10,000 g and up. Rocks and boulders are generally cheap. Here's the still unfinished result:



This one is just to show the great view Mournoth has (unlike many other houses). This is from a rampart I built along the wall.
