I came up with these ideas while applying to civ council runs and wondered what everyone else thought of them. It could benefit new and old players while positively stimulating the economy. A new credit system would allow you to take out a certain amount of money and pay a specific interest rate depending on how long you plan to pay it off. Mortgages could allow you to buy a house with some or no money down with interest rates depending on how long you will pay off the house and your bank credit. The system will be intricate yet easy to understand and balanced, so money isn't just being printed. It is risky, as it should be so keep that in mind.
Example for a loan (casino/gambling disabled after taking out a loan, one loan at a time):
Rook banger Timmy wants to buy a truck to run some peaches but got his kidney stolen by @ Caden and his shoes jacked by @ Xlax . So he goes to the bank in neo and takes out a 100k loan with a 20% interest rate because that's the only amount he can get with his new line of credit.
If he pays it back within 24 hours with the 20% interest, his credit goes higher for the following loan he takes out (72 hours cooldown); the same if he pays it back after 72 hours, yet at a higher interest rate of 30% and fewer points being added. So ultimately, Timmy is happy he got some capital to get his peaches, and he improved his credit score to get bigger loans in the future if he wants.....
But if Timmy gets rolled on by Cob with that juicy new box truck of his and can't pay it back after a week. The bank takes half his money (whatever that amount may be), and he needs to pay the amount back in full by next week, or his credit score keeps going down (-10 points each day late after a week). He has two weeks to pay back the loan and must declare bankruptcy. A player can only take loans out again once that loan is paid off 5x the amount. People's bank accounts wouldn't go negative, but they can float very low and near zero.
Loan amounts/rates:
100k (500-600 credit): 20% on 24-hour loans, 30% on 72-hour loans, and 40% on one-week loans.
500k (600-700 credit): 17.5% on 24-hour loans, 25% on 72-hour loans, and 30% on one-week loans.
1M (700-750): 15% on 24-hour loans, 20% on 72-hour loans, and 25% on one-week loans.
2.5M (750-800): 12.5% on 24-hour loans, 15% on 72-hour loans, and 20% on one-week loans.
5M (800+): 10% on 24-hour loans, 12.5% on 72-hour loans, and 15% on one-week loans.
POINTS
24hr loan paid back = +20 points (100k) +30 points (500k) +40 points (1M) + 50 points (2.5M) +60 points (5m)
72hr loan paid back = +10 points (100k) + 20 points (500k) +30 points (1M) + 40 points (2.5m) + 50 points (5m)
1 Week loan paid back 5 points (100k) + 10 points (500k) + 15 points (1M) + 20 points (2.5M) + 35 points (5M)
