...I think LandDAO has good reasons for not accepting payment in installments because if clients are unable to meet the payments, it may have its own effects. However, in researching LandDAO, I found that one of their benefits is to make buying land easy. This led me to consider the idea of installment payments, which common people could also benefit from. But since they have mentioned no installment payments, perhaps LandDAO sells their land at affordable prices, as this may be the only way for everyone to buy land easily from them.
This is not possible, try to buy any NFT right now on the crypto market using payment in installments, this is simply not doable and also a reason why LanDao wont have such feature
I don't think there is also market for such service as allowing people to buy NFTs using payment in installments, if there will be such probably we will have already a token or service that will make it happen and enough to simply use it to be able to do it.
