I should return the 1K loan in a month, in case everything is ok. But given my property as a collateral, may be this can ensure that I will return the loan amount some time in the future anyways.
Thanks
Did you contact them first or they contacted you first?
How are you going to spend the $1K? Some paperwork in the government in your country? Some paperwork in a bank of your country? Do you have to send the $1K to them? Do you have to send the $1K to an "independent" third party? Do you have to send the $1K by Western Union?
It smells like you are getting scammed. Show all the info to a trusted friend that knows about business and ask for advice. Do you have a accountant? Do you have a lawyer?
