Current jumbo loans at SDCCU (loans between $625,501 – $1,500,000) is 4.75% with 0 point. Their conforming 0 point loan is 4.375%. Their high balance loans (loans between $417,001 – $625,50) is at 4.625% with 0 point. So, if the if the high balance loans drop, those with loans between $546k and $625k will be paying an extra 1/8th of a %. Daily rate swing can be greater than 1/8th of a %. So, I don’t see why this decrease in limit would make much difference.
