How it's made
I deployed all smart contracts on Polygon Mumbai Testnet. The user can mint NFTs with ERC721 standard. The smart contract map the created NFT to the rent price and the renters. The NFT owner receives rent from renters to ownerOf(tokenId). All payments are on MATIC, The NFT can list his property (house, apartment...etc) for sale. Anyone can buy it and still has the renters. NFT owner should upload image (I use IPFS as host). then add information like address, rent price, description, and the number of renters inside the house.
