Hi Dragon. Sorry for the delay in getting back to these questions. Hope you had a good memorial day.

What are the required closing costs for USDA Loans. ie
Is Private mortgage required?
There is no monthly mortgage insurance with a USDA loan.
There is a funding fee, which is financed into the loan. It is a one time, low 2% fee.
Will I obtain my own homeowners insurance and hazard, or is it through the lender.
You choose you own homeowner's insurance and hazard, however it will be paid monthly to the lender, who will hold it in an escrow and pay it when it is due for you. So you do not have to worry about the taxes and insurance creeping up on you, they will be broken up and put into your monthly mortgage payments to make things easier for you.
