Creative ways to find down payment of $475k duplex?

[Steve S.]

My lender requires 25% down so that's $118,750. Closing costs is guess would be about $10,000 It Thee than writing a big fat check, any other options y'all are familiar with to find the downpayment? Should I pursue a loan different than a conventional 30 year? I have 3 other properties with about $110,000 in equity but the LTV is around 30% on those.
