Only in the USA can you get these 30 year mortgages at a fixed rate of interest.

All other countries it is variable rates with fixed rates only available up to a max of 5 years.

Most other developed nations are monetarily and militarily subservient tribute states to the US Empire.

Access to fixed rates for 30 plus years is an exceptional privilege only available to citizens of the US- but the US global military/monetary hegemony is unlikely to remain for more than another decade and certainly not 3-5 decades.

China already has won the trade war -USA cannot fight a war of any size without rare earths and China holds a near monopoly on their supply for the next decade at least.

Enjoy your exceptional privilege while you can but do no count on it being around in another 30 years.
