There's no schedule, the stability fee compounds every block (every 15 seconds), you can borrow money whenever you want, pay it back whenever you want. If your colleteral's value has increased so much that it's above the minimum collaterazation ratio, you can just withdraw a portion of it. Technically, with a very simplistic math, if your asset appreciates let's say 20%, your cost for borrowing is 4% and you don't spend more than the 20-4=16% in any given year, you technically have a credit line that's worth 16% of your collateral every year, you can live off of, never have to pay your debt. You just need to make sure to never fall below 150% collateral then you'd get liquidated. Of course, there's potential bugs in the smart contract, etc, so don't put more than you can afford to lose, yadi yada. edit: I highly recommend trying it or watching a Youtube video which shows you the UI and the process, it'll all makes sense and click.
