Spreadsheet using private money for down payment with owner carry balance

[Page Huyette]

Wondering if anyone has put together a spreadsheet that utilizes private money at a higher interest rate for the down payment, with owner financing or a conventional for the rest. I've worked out two separate spreadsheets, but would like to see it all pulled together.

For example: down payment loan at higher rate with shorter term. Balance at lower rate over 360 months.

If anyone has already created something like this, I'd be grateful for the share.
