You are very welcome. The majority of my experience is in home lending, and you won't be in the USA to know that the vast majority of loans for homes are invested with Fannie Mae and Freddic Mac, so no matter what bank you go to, it is their guidelines that are used for the best interest rates on mortgages.
I have just seen so many times people having to go through subprime lenders (which is mostly for people that have bad credit, but people that hve no credit go through them as well) to get money for homes and get taken to the cleaners in their rate.
Fannie and Freddie always requires at least 4 lines of credit, open for a minimum of a two year history, one must have a high credit line of at least $5,000 (that is where the major credit card comes in), and have been active for at least the last six months.
There are thousands of variables in-between, but if you follow along those, you should never have a problem getting a loan at the very best interest rates once you get here.
I also, cannot emphasize enough, that once you "mess up" your credit, it literally takes years to correct. There are tons of scams here in the USA that offers to "wipe your credit clean", etc...they are ALL scams. They will tell you that they are based on such and such law, but in the end, they don't work, and they charge a hefty fee for the service as well.
Bankruptcy used to be a relatively easy thing to file here, but not anymore. You generally will not lose your home and one vehicle if you ever have to file, but just be very careful, deal with names that you recognize (many of the major lenders have banks in Europe as well), so you know you are dealing with a reputable lender until you learn our economic system. All of the banks are required to be what is called "FDIC Insured"...if you don't see that posted on the front door, you might be dealing with a finance company that isn't a bank.
There are so many Americans that get taken advantage of every year, so I can hardly imagine how hard it must be when someone is a newcomer.
If anyone has any questions, I'll always be more than happy to help. I do maintain a state license in my field.
