Minh, I'm a FL based mortgage broker, and I understand where you are coming from. It seems to me that the individual you were talking to didn't:
1) Give you ample time to ask the necessary questions to give you peace of mind
2) Properly educate on WHY she needed certain information
I'd be happy to connect with you when to further explain, but basically she was looking to build a two-year work history for you. If you don't have a two-year work history, then you'd need to use your schooling and any internships that you might have had to fill a two year period in a way that would be acceptable for a lender.
Regarding closing costs in Florida, there generally 5 distinct types of closing costs:
1) Taxes (transfer taxes imposed by state, and taxes to record information)
2) Insurance (1 year prepaid upfront, plus 3 months of escrows)
3) Inspections (Survey, Appraisal ect.)
4) Title Costs (Florida generally uses Title companies to close, and they handle all paperwork to transfer title and insure your TItle)
5) Origination Fees (only charged by certain lenders to increase profit)
Frankly, 6% is extremely high for closing costs in the state of Florida. 3% is a good rule of thumb when calculating closing costs on most conventional loans. This does vary however, and I'd be happy to explain further if you'd like to connect.
