What part of buying a house would make my net worth go down?
Houses depreciate. Period. Things break: the hot water heater explodes, the AC cuts out in August, the roof leaks, the basement floods, toilets back up, raccoons dig up the garden. Each time something breaks, the house loses value. Every year the paint fades a little, the house loses value. Every time GE comes out with a more efficient washing machine, the house loses value. The only reason a house appears to maintain its value over time is because the money you spend repairing and improving it offsets this unavoidable depreciation. Even then, over extended periods of time it will typically just track inflation--so you're treading water. Not that there's anything wrong with that. You need to live somewhere.
