Because there’s a profit to be made.

Those percentages are pretty low. What does “involvement” mean?
The source I included above says this:
We have gone through these disclosures and identified which political representatives, and/or their spouses/common-law partners/dependents, fit into one or more of the following categories: 1) disclose residential rental property that they earn an income from; 2) disclose residential rental property without disclosing any income; 3) disclose non-residential property (vacant lots, farmland, etc.); 4) disclose some sort of other involvement in real estate (for example as a real estate agent, or with investments in real estate investment trusts).
So 128 MPs have some sort of involvement in real estate.
