According to Article 10 of the Measures for the Administration of Tax Registration:

1. If a taxpayer engaged in production or business operations fails to apply for an industrial and commercial business license or is established without the approval of the relevant department, it shall go through the tax registration within 30 days from the date when the tax obligation occurs, and the tax authorities shall issue a temporary tax registration certificate and a copy thereof.

2. Taxpayers engaged in production and business operations who go out for business operations and have been in the same county (city) for more than 180 days since the date of actual operation or provision of labor services shall apply for tax registration with the local tax authorities within 30 days from the date of expiration, and the tax authorities shall issue a temporary tax registration certificate and a copy.

If you don't apply for a temporary business license, the industrial and commercial bureau may come to trouble. I suggest you talk to the local industrial and commercial bureau to see if you can develop real estate business locally with the help of your company's business.
