You can google this stuff you know? Real estate does not fall under the securities umbrella. This is well established legal precedent, covered under Howey, the Securities Act, the Securities Exchange Act subsequent rulings.

Real estate fails the Howey test because there is no common enterprise.

If there was a startup called Homebase that was in the business of serving as an exchange where people could trade houses, the SEC might be interested ;-)

Real estate fails the "common enterprise" and "... derived from the efforts of others" prongs of the Howey test. If you decided to package real estate investment into something like a REIT, well, then you have a security. But if you're a homeowner buying a house (even a second or third house you intend to rent out), that's not a security.
