Lifetime Planner and Living expense inclusion

You would include the mortgage P+I and other asset expenses under Current homes and assets (image 1) OR you would include them as Living Expenses using Category Detail. (image 2) - but do not include them in both places.  Its your call.

Check to see if your exenses are reported correctly by inspecting the Income and Expense Summary tables for any given year by clicking on the bar chart year in the Plan:Results graph.  (image 3).   In my test file example, I purposefully included P+I in Asset Expense and Category Detail to illustrate how they are reported in the table and an example of "double dipping".  Disregard the rounding errors...

Personally, I account for all my home expenses PITI, maintance and improvement expenses as part of my asset expenses (image 1).   Including them here, IMO, makes it simplier or less confusing to do "what-if" scenarios around home buys and sells in the future.    Also, these are future planned expenses and not subject to what I've spent in the past.   My take....

Good question,  its easy to double dip when setting LTP up, for sure.  Hope this helps.
