Trying to get 10% down or less on owner occupy new construction

[Levi F.]

I am working on financing an owner occupied 4-plex construction project. Is 10% down realistic?

My plan was to bundle the lot and construction together. The builder will buy lot after pre-approval and contract. He will then build the structure and apon completion I finish the loan and pay him. Builder is on board but bank is asking for 20% down. The project is upward of 700K and 10% makes a huge difference. We just sold our primary residence to fund the project so we no mortgage other than two rentals which have 28 and 27 months of rental history and are in LLC's.

Opinions please

thanks
