Seller Financing + Bank Loan?

[Nate Monson]

I came across a triplex today that is selling for $155,000 that has the potential to be seller financed up to $120,000. I'm wondering what other people have done to come up with the other difference (in this case $35,000) if you did not have the cash on hand. Would a bank loan the rest or would you have to go private financing or another route?

Thanks!
