Evaluation Real Estate within Acquisition

Dear Searchers,

I am performing a self funded search in Germany and meanwhile came across several deals where the real estate is part of the transaction. However, in all the cases so far, the owners seem to evaluate the associated property way higher than I do. Those are commercial properties that are necessary to run the business and closely attached to the business itself. I am therefore applying a valuation that combines real estate and business, and apply a discount on the property evaluation to the standalone market price. This is mainly based on assuming that the business cannot be easily transferred to another location, while the overall return for the seller of selling company + real estate will always be higher rather than closing the business and just selling the real estate.

It seems however that owners are still sticking to their high price expectations because a Real Estate Agent told them their property would sell xyz. I start to believe that there is a major downside in businesses that own the real estate and would be really interested how you guys evaluate and calculate those kinds of deals?

Thanks in advance! Cheers,
Jonas
