@Ned J.
I actually agree with most of what you're saying. The only thing I disagree with is your statement about paying off a loan. I do think there are many benefits to paying off a loan. Let's say I own a $250,000 loan with a conventional FHA loan around 3.5-4.5% interest well with interest now I'm closer to 400k on what I owe.
We should always remember that your home loan is your principal and interest that 250k home isn’t really 250k it’s more like 400k that’s what I would actually pay for if I made every payment on time during the lifeterm of the loan.
So every time I make a payment directly against my principal in the beginning of my loan I am actually saving myself a lot of money. I put 50k towards that property I mentioned earlier directly against the principal. In doing so I:
1.) Took seven years of payments off of my loan
2.) Saved myself 43k on the total cost of the loan that’s close to 85% return on my cash investment.
Now it’s careful to note I don’t think it’s the end all be all solution. For example I don’t think you should make principal payments towards the end of the loan. At that rate nearly all of your money s being invested towards the principal and you’re not saving as much on your interest or decreasing the lifetime of your loan.
Long story short I think there are advantages and disadvantages to any path you choose, whether that be 15 vs 30 vs paying off your loan. It all depends on what you’re trying to accomplish. Just make sure you understand the pros and cons to Both and choose what’s best for you and personal situation.
