After basically seeing how the land grab happened on Balmung and apparently across other servers too I'm recommending some changes be done to the house system.
FCs can only own one house same with Personal House. If they want to have another house they must make another FC and obtain a certain rank level to purchase a house. The reasoning behind this is to stop people from price gouging the housing market and give players a chance to buy a house at fair market value. This would also fix the issues on Legacy servers where the prices are so high that small FCs or people who casually play can't even afford a house.
There should be preset housing on the lots that require you to purchase a permit to perhaps upgrade or alter the look. This way the lots are filled with a house. The whole buying the plot then having to buy a permit to even build is crazy. You might as well start charging a monthly mortgage on these houses based off their location while you're at it.
To be continued...
