It has been a very long time since I've looked at any marketing material, so please help

It is my understanding that you can list a rate (e.g. 5.50% - 1.5 Points) - should we also show "APR" nest to the rate?
Also, if you list something like 80% LTC to $500,000 - is this a triggering term? or 75% LTV to $200,00.
If the flyer shows a percentage offering a rebate if a lot loan is rolled into a construction, is there any thing we should be aware of?
