It depends on how the assets are classified (investments vs a business), and for CSS Profile, each school’s proprietary formula.
Real estate beyond a primary home will have to be reported on FAFSA and CSS Profile (for your schools that require Profile). Equity in a primary home is reported on Profile but not FAFSA.
If classified as an investment, on FAFSA the net worth of the assets will be assessed at 5.64%, after an asset protection allowance. That amount is added to your EFC.

For Profile schools, run the NPCs. The degree to which schools assess the primary home and investment real estate varies, a lot. Some schools don’t assess primary home net worth, some do. Some hit investment real estate hard, up to 20%-25%. You just have to do the NPCs to see what your estimated COA us at each school.
If the real estate is considered a business, the impact to what your family is expected to pay can also vary from school to school. Follow directions closely for both the EFC estimator and NPCs, it’s a lot of detail.
