Yes you may purchase a house in the United States and use if for any purpose you so desire, you need not be a citizen of the United States.
If you are applying for a mortgage loan you might want to speak about the use of this house with your mortgage loan officer. The purpose of the house would depend on your interest rate. You would also need to have the documents necessary to be approved for a mortgage loan, whatever is equivalent in your country to the Untied States as proof of income, paid taxes and pay stubs.
You would have to make sure you have the proper immigration documents to enter and stay in the United States.
I hope this has been of some benefit to you, good luck.
There are no restrictions in the US on property ownership by foreigners. Plan on NOT being able to get a mortgage – foreign purchasers pay cash (even for multi-million dollar condos). And remember you will be subject to 35% withholding tax on sale of the property.
Owning property does not, however, qualify you for any visa! Most foreign owners have visa waiver for up to 90 days, or for Canadians, visa-free entry for up to 180 days (lots of "snow bird" retirees wintering in FL or AZ from Canada). If you need to get a visa, owning property in US can make getting a visa difficult as your property is "ties" to US. Make sure you have extensive ties such as job, business, properties in your own country.
How many celebs and millionaires have houses all over the place?
As long as you have the money and pay the bills and taxes you can do what you want.
Sure – but owning a property does not guarantee that you will get a visa. In fact, unless you have considerable assets in your home country, it could make it harder to get an entry visa.
oh yea, especially if you are paying cash
you might not be able to get mortgage loan for one
If you have the cash to do so!
