How to structure an offer for $650,000 for land

[Joe Garvin]

Hello BP Community,

We want to make an offer for a piece of land that the asking price is $650,000.  We want to offer full asking price but request owner financing over a 10 year period offering 1.5% and a balloon payment of $50,000 on the 10th year.  Does anyone know f a calculator online that could compute this?

Thanks in Advance!
