Final answer:
Chuck's closing costs are $2,700.
Step-by-step explanation:
To calculate Chuck's closing costs, we need to add up all the fees.
The origination fee is 1% of the mortgage amount, which is $90,000 x 0.01 = $900.
So the total closing costs are $400 (title search) + $500 (appraisal fee) + $900 (application fee) + $900 (origination fee) = $2,700.
Therefore, the correct answer is (C) $2,700.
