Wouldn't dream of owning Quicken. Not really tough to know what your portfolio vs. the cost of capital.

Quicken was just a metaphor for the processes necessary to service the various debts.
I completely understand the power of using leverage to maximize ROI on capital. I also understand that any strategy involving debt carries with it a certain amount of inherent risk. IMHO, the few hundred dollars gained playing the spread is not worth putting the stability of the family finances into play.
Scenario A; Its' one year ago and you have $30k in cash. You can buy a car or you can invest it. You elected to invest because car loans are 7%, and the market averages 12%. Because of the lower cost of capital, you are making $1500/yr over and above the car payment. Two years pass and recession (or whatever this is) hits. Subsequently, you are laid off. You remain unemployed for 6 months and cash is now at a premium. The car (complete with $500 payment) is under water and you cannot sell it without incurring a loss. You can sell the securities, but they are down 25% from last year (a $7500 loss). Desperate, you sell the securities for $22,500 and pay off the car. Two weeks later, the transmission dies ($2000) Final outcome: $30k gone, $2000 in add'l debt, but no car payment.
Scenario B: You pay $30,000 for the same car. Having no car payment, you pay the same $500/mo into a fund for the next car. Two years pass and recession hits. Subsequently, you are laid off. You remain unemployed for 6 months and cash is now at a premium. Two weeks later, the transmission dies ($2000) Final outcome: $30k gone, $10,000 ($12k-2k) in the bank, no car payment.
Given those two scenarios, which is going to create more stress on you and your family? Which forces your decisions, and which frees them? If it happens to you, was it worth the extra $1500/yr?
Don't get me wrong, I am not against investing. I own my own business and have worked damn hard to accumulate a decent net worth, the vast majority of which is in the market (I'm only 40). But I do not invest money I need short term (<5yrs) or place the needs of my family (food, shelter, and lights) at risk to make a few extra %. If I need $125/mo that bad, there are a hundred different ways I can make that on any given Saturday (before noon...) and never jeprodize the stability of my household.
