How can I use the BP Calculators and consider a 2nd Trust Deed?

[Dolly Caswell]

I'm an avid fan of BP and especially appreciate the calculators in "Tools" that have been provided for us, however, I'm finding a need to consider "alternative financing" such as making offers to include 2nd trust deeds as part of my decision process. I don't see a way to "click" and input other financing, does anyone know how to include that or can you suggest a workaround? While I'm at it, is it possible to consider assumable loans and a remaining life on the loan of maybe 3 or 5 or 9.5 years (for example) at XX% with a current balance of XX? Or can you suggest a workaround for that as well? Thanks for your help.
