"Blockchain will transform the real estate industry. There's no doubt about it, and the earlier entities get on board, the more they stand to gain in terms of security and efficiency," said Tony Franco, CEO of SafeChain. "Starting with something as relatively straightforward as property transfers, blockchain creates a decentralized, near-perfect audit trail that can never be lost or stolen. Eliminating that risk opens the door to completely changing how properties are bought and sold in the U.S., and those changes will ultimately be to the consumer's benefit, as well as the real estate industry's as well."
The BauGB defines the Verkehrswert or Marktwert (market value, both terms with identical meaning) as follows: "The market value is determined by the price that can be realized at the date of valuation, in an arm's length transaction, with due regard to the legal situation and the effective characteristics, the nature and lay of the premises or any other subject of the valuation" (non-official translation). The intention, as in other countries, is to include all objective influences and to exclude all influences resulting from the subjective circumstances of the involved parties.
Also, ask the agents to call the listing agents of pending sales to try to find out the actual sales price of those properties. Listing agents do not have to disclose the sales price, but many are happy to help out because they could find themselves in the same situation. You can always ask if the agent thinks your price will appraise if the agent refuses to divulge the pending price.
