Asset Ownership

Since I only own 50% of my homes I would like it to reflect that as my net worth, not 100%. Is there a way to do that?

Yes.

For every asset, you can set your ownership and the asset value will be calculated according to that.

Go to the asset details (click on the 4-line icon on the right side of the row) > Go to the Assorted tab > Find the Ownership Percentage field and enter 50% instead of 100%
