Log what a project actually costs as you go: refurb invoices, legal fees, agent fees, utilities and mortgage payments while you hold it. Log the income too, including recurring monthly rent on a lease.
Because TakeFlight already holds your analysed figures, you would see actual against analysed side by side, and your real break-even point rather than the projected one.
Vote if you would use this, and tell us in the comments which costs matter most to you.
