Financial questions that need an answer

I am worry about the USD dollar inflation/depression

I am not sure if I should invest in gold or buy a house (some property) to keep from the lose of USD.

The gold price is a little high now, so I might lose money later.

With the house price going down, I think maybe it might be better if I buy one and sell it later, when the economy picks up??

I am not sure which option is better, please give advise.
Thanks
