Hello, I'm a mortgage professional.
There are several steps. Generally after you apply, submit your income and asset documents and get pre approved you then find a home, get a contract, submit whatever other paperwork the bank needs, order the appraisal, get the loan approved by an underwriter and close. There are a few other steps in there.
I can explain more.
If you have any other questions or would like help with this you are welcome to get in touch with me.
