Xero — Cash flow view (with principal pay down)

[Spencer Smith]

Started using Xero last year, as better bookkeeping was needed a new acquisition with a partner. Previously I'd always used Stessa, which has a great Net Cash Flow statement view, breaking down the usual income/expenses, but also includes a section for Interest/Principal, and another section for CapEx. At a high-level, I'm looking for a single page that will show the entire health of the property, from income/expenses, to debt coverage, capex, ROI, etc. Stessa had this all done by default. I'm finding it hard to believe that Xero doesn't have the ability to do this will all their custom reports stuff.

In Xero I can't figure out how to get a view in a report how much the principal has paid down over the selected time period.  I track the principal as a Liability account in Xero, and whenever I add it to a report, it always shows the current balance, rather than the change over the chosen time period (like with expense accounts).  

Any idea how to get principal pay down in a custom report?

Anyone know how to account for CapEx (setup as Asset accounts) expenses in the cashflow?

Maybe does anyone have a solid high-level example of a good Cash Flow statement in Xero?
