To add to what Beix mentioned as she pretty much mentioned it all I just want to add a couple of things. If one day you plan to sell your beloved house you need to keep in mind several things:
Who do you see living in this house? Are they wearing the Nobleman outfit? Do they like solitude? Do they not care about the size? Do they not like paying so much rent? Etc. Think about what you like about the house and why you originally picked it and how much it means to you.
The market prices right now in your server might differ based on numerous factors. The time of year, population, the hot town to be in, etc.
I personally love the look of certain towns and a lot of people can agree Venore or Yalahar houses look stunning for the most part.
Your home is where you hunt in as well. What spawns are in Ankrahmun? The mother Scarab Lair? Maybe promote the spawns.
The last thing I'd like to add if your going to get rid of a house, plan beforehand. Is it worth the rent to try to find another owner or would you rather ditch it if no one buys. Make sure you check your worlds Trade Boards to get an estimate of the house prices at that time you plan to sell. I noticed prices change on a daily basis at least on my world.
