Nanwa - In a typical indirect auto portfolio, you are orginating loans from participating dealerships you have entered into an agreement with. The agreement will cover issues such as the reserve schedule you pay as commission. Typical agreements theses days may pay the dealership 75% of the spread (reserve) upfront, with a no charge back policy after a set amount of days (in the event of early payoff). It will incorporate rules if a vehicle is repossessed (ie: full chargeback of reserve), an amount to maintain the the reserve account at all times, and other policies such as the rate spread cap (usually 3%) - so if your discount rate is 4% to dealer, the most they can charge customer is 7%. Other things such as your policy on accepting contracts with credit insurance, extended service contracts, gap insurance all need to be figured in. There is terminology in the Indirect business called "line 3 and line 5". Basically, it means if an application is submitted for $15000 and you approve it, normally they can then add on the financing of extras such as credit insuarnec, etc, which can easily boost that loan amount to $20,000. Not a huge risk because they are all cancellable and refundable on a pro-rated basis. You need to consider what applications you'll accept and what method - some use fax, some use dealer software. What contracts you'll accept. Lots of issues that were around 15 years ago no longer exist, but you should be aware of them. Banks used to accept "full recourse" deals, so if you approved a loan that was horribly below your guidleines, a delear may offer to provide full recourse, meaning if the loan went bad, they would staisfy the contract and go after the customer or vehicle themselves. Rule of 78 loans used to be very popular - not anymore. Funding of contract can be done via drafts or via ACH. If your program was to be of any substantial size, you will need appropriate systems to underwrite, validate, and fund apps & contracts.
As far as collections - that all depends what your philosophy will be. We have a portfolio of about $160 million, but we have established ourselves over the past 15 years as a conservative lender. We trade great rates for basically "A" paper, and consequently, our losses are negligible. We may lose some opportunities, but this has worked for us in a crowded field.
So much more to consider, also. Rate structure - tiered or not. rates based on year of vehicle? How much will you advance (loan value on used, invovie or msrp on new...)?
Staffing - sales person/buyer/input & validation clerk (operations).
I could go on and on!
