What was the total income from the PPP program this quarter 
Curt. Thanks for that question. We have invested significantly over the last five years in technology, so we view this as a continuation and acceleration of the pace of that investment as we move forward. So things that we had on the road map that maybe we wouldn't get to for 12 or 18 months we're trying to accelerate that as quickly as we can. One specific area is electronic signatures and documentation and things like that. We're on a journey to get all of that electronic. We're going to do that as fast as we can. Most of the technologies we would just be continuing to invest and develop versus any new specific technology as we feel pretty good about where we stand relative to the peer group in customer technology capability and internal technology enablement.

That's great. I appreciate your thoughts on that. And then the last question was just a follow up to the comments on expectations around core commercial growth in the fourth quarter being sustainable. Just any comment on the drivers of that, whether it's a particular geography or product? And then to the extent you have a view on how 2021 organic commercial is shaping up. That would be appreciated. Thank you, guys.
Curtis J. Myers -- President and Chief Operating Officer
Yeah. Just overall on commercial loan growth, we continue to grow in most markets. Our team has remained focused on business development in all of our markets. We hope to not have the headwind of line utilization reductions. So if that's stable or maybe provide some benefit in the fourth quarter that will certainly help. So we really expect the fourth quarter to be more like the third quarter where typically we get a ramp-up in the fourth quarter. We're expecting at least stable. And if we can get that to ramp up a little faster than the third quarter that would be great.

Just curious, what was the total income from the PPP program this quarter?
Mark McCollom -- Senior Executive Vice President and Chief Financial Officer
So PPP you have two components. It's a 1% interest rate. And then our accretion of the fee is $2.5 million per month, because it adds 1.5% to the coupon. So take $2 billion at a 2.5% yield. And that's how to think about it.
Matthew Breese -- Stephens Inc. -- Analyst
Got it. Okay. And then just thinking about the growth outlook, you discussed mortgage continuing to be a driver there as it has been. How much of the loan portfolio are you willing to dedicate to residential mortgage given your commercial background?
Mark McCollom -- Senior Executive Vice President and Chief Financial Officer
Yeah, yeah. When you look at our asset sensitivity, we have plenty of room. We're one of the more asset sensitive banks in our peer. So we think that it's appropriate for us to be able to add incrementally to what we've done historically to take off $50 million to $100 million a quarter in fixed rate residential production and put those on the books over the next couple of quarters. So I mean, it's not going to be a sea change, but we think there's room to have some incremental growth in that asset class.
Matthew Breese -- Stephens Inc. -- Analyst
Okay. And then just tying this back into the mortgage gain on sale production. I think you said, total originations this quarter were $902 million. Is it right that you sold, what was it, $600 million or so, is that correct?
Mark McCollom -- Senior Executive Vice President and Chief Financial Officer
Yeah, that was the lock amount. Yeah, it was $608 million.
