If I understand, you want to buy an house and use it as collateral. Loaned amount will be tokenized and each token will give a % of property of the house.
Seems a good Idea, but you have to consider that until buyback will be completed house will not be fully yours, so can happen that some token holders will ask you an extra price for sell his tokens!
Otherwise can happen that if you are dishonest and won’t pay you due on time, some tokens holders should sell his tokens at lower price ( so you will be encouraged to pay late).
Is not easy as seems
I was just thinking, a lot of houses near me sell for $50 000 to $100 000. If I used a token to represent each share of the house and bought them back at $1000/token at a time with each user gaining 4% of the value of their token every year, would that work (having everything held by solicitors in the mean time). I can't get a mortgage as my earnings are international and the bank managers have caught on that I could just easily disappear... Each token would be bought back on a semi monthly basis?
