Daniel,
Nope.
If the seller wants a minimum of 25% down and you want to 50% that's OK. You have met or exceeded the minimum. The Escrow Company or real estate attorney holds your $80,000 in escrow to give to the seller and you take out a loan for the balance, in this case only $110,000 plus some closing costs and fees.
Your down payment is not in addition to the 25%; the 25% is included in your 50%.
Best of luck
