This is the most contradictory post to my experience and knowledge.
		
		
	 
OK?
	
		
	
	
		
		
			1. An unsecured loan is an unsecured loan. The only thing that matters is the bank. A standard, flat payment loan will standardize your interest rate and make your payments steady.  How is lowering your interest rate a bad idea?  If the costs of the lowering exceeds the savings over the life of the loan or don't make it worth while, then you have a point, but I highly doubt going from 20% to 12% on a 10k loan would fall under that category.
		
		
	 
An unsecured loan is usually in the 12%+ range (aka signature loan).  He probably can't get one for less than his credit card is at (most places only give signature loans to people who don't need credit).  An unsecured loan at a credit union is rarely actually unsecured (cross collateralization).  Let's say you default on your unsecured loan but you also have an auto loan through them and a deposit account.  First, they'll intercept any dollars going into the deposit account for the unsecured loan.  Second, they can seize your automobile.  Let's say you finally bite the bullet and file for bankruptcy.  Few credit unions will allow you to only reaffirm part of your debt.  So let's say you owe $5k on a $15k truck and you want to reaffirm that debt but you want the unsecured loan discharged.  They're going to say bugger off and take your truck.
	
		
	
	
		
		
			2.  Falling behind on a credit union account is no different than falling behind on a credit card.  In fact it may be more advantageous to do it on a credit union.  Why?  Credit unions are localized, customer based entities who generally listen to their customers and work with them.  Credit Cards don't.  On top of that, in my personal experience, I fell behind quite a bit for a while and it had absolutely no affect on the 2 credit unions I use other than affecting my credit score.  Again, when I was applying for a loan with the UMCU they sat down and actually talked to me.  I explained why I had some late pays and they came back and approved a loan they wouldn't have approved otherwise.  A normal large bank would just use metrics to quantify your loan and approve/decline based solely on that.  no amount of explaining will do anything to help you.
		
		
	 
Credit card company can only send you to collections.  Read the fine print on anything related to a credit union and you may be surprised.  Credit unions want happy members that spread the word about how great they are.  Credit unions do not play by the same rules as a "bank".
UMCU is not your typical credit union.  Try the same thing at a normal credit union (like say Sagelink) and they will tell you the same thing as Chase.
	
		
	
	
		
		
			3.  Every time you do a credit search to expand your debt your score goes down 2-3 points.  From the sound of this situation, he's not sitting on a whole heap of cash and just wants to waste his time paying a debt off.  He's hurting and his credit may already be hurting.  The longer you have a high balance on a credit card, the faster your score plummets.  When I did my debt consolidation loan a while back, my credit score spiked up almost a hundred points within the first month of doing it.  Opening up new cards all the time or playing the 0% interest game does not work in most situations.  It kills your credit score which greatly restricts your ability to get new cards and has potential to become a big problem (talk about that later).
		
		
	 
Hard pulls hurt.  Soft pulls don't.  15 searches at one time is the same "cost" as one.  Otherwise, when people went to buy a car don't you think their credit score would go down 100pts when the monkeys at the dealership bang on the keyboard to 30 different financial kickback institutions?
Revolving debt is relative as far as much as it hurts.  Having $4k on a $4500 credit card hurts.  Having $4k on a $15k credit card does not.
Store cards hurt the most as many of them do not publish a credit limit.  Most of the retailers do this.  So having store credit cards usually hurt.
0% game works as long as you keep the cards active and you aren't opening a new one more than every 9 months.  In fact, it can even help because if you carry a lot of debt but have a lot of available credit that proves that you are capable of making the payments.  I'm sure the many people here who work at dealerships can tell you all about the people that roll in to buy a new Lincoln that have $100k in revolving debt and have a credit score above 800.
	
		
	
	
		
		
			4.  Paying off the highest one first is a good idea, but again, he sounds strapped for cash as it is and while paying 10$ extra will help over time, on a 10k debt load he's not going to whittle it down any faster than if he had a fixed payment loan.
		
		
	 
Fixed payment loan at what interest rate?  What part of a credit card is not a fixed payment loan, assuming you are not adding more debt?
	
		
	
	
		
		
			5.  When you call a credit card company and have them put you on a hardship program here is what happens.  They close your card, lower your interest rate, and payment.  Sounds good right?  Sure, if you can't get a fixed payment loan from a CU it does.  This will destroy your credit.  it raises your credit to limit level to a massively high percentage.  Which causes your credit scores to drop like crazy.  It also shows on your record as having been in a credit repair status.  Most banks when they see this will absolutely find this as a huge red flag.  You almost are better off just filing for bankruptcy as opposed to this option.
		
		
	 
You don't agree to a change in terms with your credit card company.  I know I said that already.  What they do is put you on a loan program that is between 10 and 30 years at the same APR or higher.  What's worse, is they often recreate the loan every 3-6 months so it looks like you *just* started paying on it.  What you do is negotiate a lower interest rate on your credit card.  This used to be easy, but it is more difficult now.  Citi will tell you to go pound sand.
	
		
	
	
		
		
			6.  The biggest thing you're not talking about is the fact that a credit card is a revolving compound interest account.  This means you're constantly paying interest on money that you already paid interest on.  A flat payment loan does not do this.  This is a huge savings and allows you to pay the loan off in a guaranteed amount of time.  The other thing is it's obvious that most people looking at this type of option aren't looking to just dump 2k in credit card debt.  They are looking at large sums.  They aren't going to pay that off overnight by any means.  There's no guarantee what will happen in your lives that may stop you from making a payment.  What happens if you are late on a credit card that you are at 0% interest?  It spikes and majorly.  There's no federal law which caps what your interest rate can go up to.  State laws do but Michigan does not have a maximum that it can be increased to.  Most cards push it up to near 30%.  What happens if you are late on a credit union loan?  You pay a late fee, but your monthly payment doesn't go up.  Most credit unions don't have an early payoff fee either, so if you do put that extra 10$ in and pay it off faster, you're not hurting yourself at all.
		
		
	 
All of my "credit" accounts are calculated using average daily balance with the exception of my mortgage.  But, I only have one non-mortgage non-student loan left and it's through Harris NA.  Or was.  I haven't seen any modern loans that don't use compounding interest.  Simple interest is slowly going away.  Why wouldn't lenders earn interest on unpaid debt (including unpaid interest)?  I think the only reason it wasn't used before is because of no "e" key on a calculator.
When you sign up for a credit card you agree to the terms.  You are correct, there is no national limit on penalty interest rates.  Most national lenders are based in either Delaware or North Dakota because even though there are states that set maximums they only apply to the institutions within that state. 
Depending on the terms of the "personal line of credit"/"unsecured loan"/"signature loan" there may be a pre-payment penalty and there may be a penalty interest rate that can be triggered by a single late payment.  You have to read the terms of the loan.
I heard that there are these things on the Interwebs that make payments automatically for you.  There is no excuse for making a late payment on anything.
