Edit: I should say anyone can buy a house for 20% down or less. In much of the world some can do this, but credit is not extended to nearly as many of the population as it is in the US
With government assistance programmes it can be even 5% down but you'd have to qualify for some protected category.
Good luck!
Also, in case there's some confusion, "deposit" and "down payment" are distinct. In American real estate parlance a deposit is earnest money (often 5% of the initial offer) to bind the seller into closing--the process of finalizing contracts among all involved parties, and transferring assets. A deposit might be forfeited if the buyer pulls out. A minimum down payment is the minimum equity a mortgagee (e.g. bank) requires the borrower to hold in the property as a condition of making the loan.
I don't know about "anywhere else in the world" but I can guarantee you that you can buy a property everywhere in EU with a 20%. Also, property taxes in EU are generally lower than US.
I keep saying that americans, pay lots of taxes, they are simply not aware of it.
> The average annual wage in 2019 in the US was $51,916.27, and the median annual wage was $34,248.45. The median wage is the wage “in the middle,” while average refers to the measure of central tendency for all the data.
