That 5.875 lender had over $2k in closing costs. In my area truly no cost loans are in the 6.6% range.
These are 30 year fixed conforming loans.
ARMs (adjustable) can be had for below even the money the bank can borrow at right now, however these are bad moves as rates can only go up and often these discounted ARMs have caps that are insane. An ARM only makes sense right now if you are planning on selling before the first adj. date.
As long as rates are 8% or less people will buy homes a lot....only the refi market will take a hit now. Once loans approach and pass 10% you can expect a serious decrease in purchasing. However, I doubt we will see that anytime soon. I think loan rates will creep up and settle at or near the 7.5% mark over the next year or so and then slowly go up and down around that.
