You are almost always better off with a VA loan if you can get one.
Not only do VAs offer 100% financing (conforming loan limit for VA loans is $417,000 in most parts of the country so it is likely that at 330K you qualify for 100%) but you also are not required to pay monthly mortgage insurance premiums.
There are the VA funding fees that have to be paid which varies based on the type of military service you performed and also varies based on if this is first time loan or second/third... loan. Yes, you can take out VA loans more that one time! If you are a qualifying disabled Vet then you will never pay any VA origination fees.
Did you mean tax rate or interest rate at 3.25? You really need the interest rate, tax rate (annual or monthly stated) and homeowners insurance rate as well as your VA service level to calculate the expected payment. Can you supply those details?
