What are soft costs in CRE?

Could you please elaborate on what soft costs in CRE entail? Are they related to the direct expenses associated with property acquisition, development, or management? Or do they encompass other, less tangible factors that can impact the overall financial performance of a real estate investment? Understanding the nuances of soft costs is crucial for investors and professionals in the industry, so I'm eager to gain a clearer picture of their significance and potential impact.
