Is there any Leasing Management module for Openerp? Features that I'm looking for are

• Payment calculator with different interest rates and rules

• Integration with accounting core for down payment, installments, cancelation and interest rate 

• Integration with warehouse

• Recurrent work automation or reminder

• Credit approval process 

 I found a rental module for odoo version 7 but first of all it doesn't come with all features and also I need it for v8
