For someone who is buying lands from LandDAO you have every right to engage in physical verification and confirmation of your lands of you are not convinced with the use of GPS to track the location of the land. You also have the right to send a representative to confirm the lands on your behalf before involving your surveyor and legal representative to document it.
You have got nothing to fear before purchasing land from LandDAO because they have legal documents to all the lands they acquire.
If I'm purchasing land from any real estate company or LandDAO or whichever party is involved, I won't have to talk about the physical visiting of the land much, because I know that I can always hold them to make provision for what I have paid for, but in cases where such parties or companies are the ones to be buying from rural areas or I myself am buying from rural areas, physical assessment is important just to be sure that what you are paying for and registering is exactly the same way that it's described before it can be added into where it could be easily tracked.
LandDAO is a digitalised real estate firm with an integration of blockchain technology so i believe that security would be a huge part of their priority to enable them satisfy their customers, I also believe that they'll help customers keep track of every land purchased through them, that why they won't purchase lands with family or community dispute that would later affect customers on the long run. My own question for the management is that, would their be any form of referral program to attract more customers, or what ways would LandDAO use to attract their customers and what form of appreciation would be given to customers or those who refer other customers to the project?
