First let me say that I'm all for housing being somewhat expense and something to work towards.
However, I feel that the current suggested prices will have a negative effect on the game and it's economy.
It was mentioned before by the devs that they hoped the demand for housing and furniture would help alleviate the flood of materials and items on the market that have pretty much ruined the economy. I am a crafting enthusiast myself and I can say with confidence that most FCs that can afford a house will not need my (or anybody's) crafting services. They can and will craft anything they want or need and the market will remain stagnant with either materials or furniture that not many people can make use of.
I guess what I'm trying to say is that the economy is garbage and cannot support the suggested prices of land. This looks like it will be a huge bottleneck.
