The only good benefit of an interest only loan is the lower payment. Specifically you have extra cash flow to do something else with it verse paying down the house. Something really popular right now are Pay Option Arms. Each month you can either pay Interest Only (IO), Principle and Interest (PI), Minimum Payment which is using equity from your property while you are there.
GW Bush has a pay option arm on his ranch.
Back to your question. If you are dealing in multipal propertys that you flip from time to time, then a pay option arm is perfect because you don’t tie up cash.
If this is your own home to live in then I recomend in most cases a conforming 30 year fix.
Arms are a more complicated animal.
Conforming loans arms are called 3-1, 5-1 etc…
Non conforming loans a 3-1 is called a 3-27 and a 5-1 is called a 5-25.
Non confoming ARMs are always lower interest then their fixed counter parts with the same bank. I’m talking about sub prome banks now.
Conforming Arms at banks are not always lower then their fixed counterpart at the same bank.
Right now for a conforming loan fixed loans are pretty close to the same interest rate as the arms. Hence one might as well get a fixed. If fixed sky rocket and the banks want to sell more Arms then the Arms might be lower.
If you getting a conforming loan backed by Fannie mae or Freddy mac and your going to stay in the home, I would get a 30 yr fixed interest rate. If you can afford more then i would add some extra money each month towards the principle. You can pay off a 30 year loan in 15 years easily just by adding a certain amount.
You asked about charging.
Brokers have several different fees.
Points on the back called YSP (Yield spread)
Points on the front called pre paid interest
Points on the front pre paid interest to get you a lower rate
3rd party fees, IE Appraisal, title, closing costs
The definition of 1 point is 1 percent of the loan. The broker can charge you anything you allow.
Each broker has overhead, the nicer the facility, the more brokers, usually more overhead the more you are going to be charged.
The question is, how many total points are you going to allow?
Listen carefully here:
This is what you do.
Figure out one loan type you want, ie 30 year fixed, X interest rate, X loan amount, conforming loan.
Obtain the good faith estimate and look how many points total your being charged.
Find another broker and have him quote the same loan. Tell this broker you you have a competitive quote but don’t tell him the number. Make him work for you.
Eventually you can go back to the first guy and get him lower. It’s not uncommon to only pay 1 point for the loan, which is a great deal.
The first guy that quotes you will try and charge you 3 to 5 points usually.
Try and find a broker who works by himself, has low overhead and does it on the side. They tend to charge less then people who only do this for a living.
I will end here. I could talk about this subject for days.
