I never knew I would make this decision at the time of purchasing the property so I paid little as possible on the down payment.Fast forward to one year later.  

Therefore, lets look at it as if each decision is a set of two investments (one for the car, and one for the property), each with independent cash flow and equity:In Scenario 1, the car is bought for all cash, leaving no money left to invest in property.
