When you're finally ready to finalize the purchase of a new home and have a mortgage ready to be signed, you may be responsible for paying up to several thousands of dollars in fees associated with the mortgage closing upfront.

Any professional work or documents that need to be prepared to finalize the purchase of your new home may increase your closing costs substantially. In some cases the seller may agree to cover some, if not all of the closing expenses. Otherwise, you'll be responsible for paying these fees at closing, which range from 3 6 percent of the total mortgage loan price, out-of-pocket. Fortunately, you may be able to deduct closing costs from your yearly taxes if you pay the closing costs in a lump sum payment.

Some of the more common closing costs you may have to pay include:

Processing Fees

Application fees and fees for accessing your credit report when you first apply for a mortgage. These fees are usually nonrefundable if you arent approved for the loan or dont make use of the loan. Loan processing fees may cost anywhere from $350 - $550.

Appraisal Fees

The fees charged by a professional appraiser who inspects the home before purchase to verify its market value. These fees cant be deducted from your yearly taxes. Appraisal fees may cost anywhere from $300 - $400.

Origination Fees

A flat fee or percentage of the mortgage loan value charged by the lender for all the costs associated with prepping the mortgage. This fee is typically 1 percent of the loan amount. For example, you would pay $1,000 in origination fees on a $100,000 mortgage. Some online lenders have eliminated this fee.

Discount Points

Points are the monetary equivalent of a percentage of the mortgage. For example, 3 points is the same as 3 percent of the mortgage price. If you have extra money you can pay the mortgage lender discount points, which will lower the interest rate youll pay throughout the life of the loan.

Document Preparation Fees

The costs of all loan papers generated and processed throughout the loan process.

Attorney Fees

Any costs related to attorney representation of both the buyer and seller. You may be responsible for your own attorneys fees as well as the sellers attorney fees.

Title Insurance Fees

A one-time fee you pay to insure no monetary losses caused by title defects, liens against the property or other title problems regarding the property that may not have been resolved before you purchased your home. The insurer will search public records, fix any potential title problems that can be fixed before the title is issued or exclude the items in question from your policy. You may pay more than $400 for every $100,000 in home value for title insurance.

Home and Pest Inspection Fees

Fees that may be required by the lender to pay for inspections to verify your home is structurally sound and free of any insect infestations.

Insurance Fees

The premiums you must pay to open homeowners and hazard insurance policies on your home. These premiums must be paid by closing.

Private Mortgage Insurance (PMI) Fees

Fees you'll probably be responsible for if you're making less than a 20 percent down payment. Private mortgage insurance protects lenders against loss if you default on your mortgage loan.

Survey Fees

Fees the mortgage lender may charge to have a surveying company verify the boundaries of the property you'll be purchasing.

Prepaid Interest Fees

All the interest that accrues on your mortgage before the first payment must be paid in advance when you close on your loan.

Assessment Fees

Additional fees you'll pay if you buy a condo or property governed by an association.

It's important to get full disclosure of all related closing costs before youre ready to finalize your mortgage. Otherwise you may end up with a very costly surprise when it comes time to sign the dotted line.
