40 % APR means that you will get 40% of the amount lent in terms of interest after 1 year.

Since you may not believe me that I will pay back in 1 year (and the lease period may not coincide with 1 year) I reduce your risk by making daily automatic payouts of 40%/365=0.1096% per day (so you do not have to wait a year for your reward and you may retract the lease if I do not pay). For a 1000 SP that would be a 1000*0.001096= 1.096 SP per day.

What the statement does not say is that I do not need a 1000 SP right now. A comfortable amount for me is from 25 to 150 SP. The time period is ambiguous right now: I'm not sure when I would like to stop, but it will not be less than a month. I will send you a message (as a comment and in transactions) when I will want to stop the lease (about a week before the date) and automatic payments. You then should retract the loan at that date. If you retract the loan earlier - the payments are going to stop automatically right away. Feel free to do it if you want to stop the lease for any reason.

Why am I doing this? Because when you arrange a direct lease you do not have to pay intermediary fees. That benefits you with higher APR and me with lower cost of a loan. Let me know if you are interested.
