What is the expected overlap between T-Mobile and AMT's properties in the US market
tial decommissioning that T-Mobile can do? I think the Sprint sites are up for renewal next year. And second question on Lat Am. How do you think about the growth going forward, given that the macro environment is weaker and the potential acquisition of or by other carriers could potentially create some churn activity? Yes. I would like to see your thoughts on how you think that could impact your growth over the next few years.
Thank you.
Tom Bartlett -- President and Chief Executive Officer
Yes. Thank you. OK. Batya, with regard to â I'm going to address the Lat Am question first.
I mean we're really excited about the opportunities that we continue to see down in the market, particularly in a market like Brazil, which is still so underserved. I mean, you could take a look at customers per site, it's significantly higher than what we're seeing in the United States. And so we continue to see the opportunities for further densification, where our build programs continue to grow. So we're actually very energized.
And our teams in the markets are very excited about the opportunities there. Yes. There is some consolidation perhaps going on in the market, but that was fully understood, fully expected. So there are really no surprises there.
And I think the government themselves, particularly with regards to what we're seeing in the pandemic, continue to want to drive connectivity and digital connectivity in their markets. So we're quite excited about that. And Oi, as you all know, represents a relatively small piece of revenues. I'm sorry, Batya, your second question on the U.S.

On the T-Mobile decommissioning activity that would come, that could start potentially next year?
Tom Bartlett -- President and Chief Executive Officer
Yes. No. You're right. I mean, those Sprint sites, a vast majority of those sites come up for renewal toward the end of next year.
We believe they're obviously very well-positioned sites, and we will likely try to mitigate it. But that current potential is possible and hopeful that between the new build that's going on in the marketplace, as well as DISH's expectations for building out, that will be successful in terms of mitigating that. But that's all part of a lot of the negotiations and discussions that are going on as we speak.

And Batya, if I could, Batya, I'll just add a couple of comments on the Sprint, T-Mobile, maybe to put the merger kind of in context with the U.S. markets. So you know that the U.S. is experiencing kind of an exploding growth in mobile data, about 30% a year increases.
We've seen accelerating deployments for 5G kind of heading our way. There's a number of new spectrums heading into the market that will have to be built out. The carriers continue to invest heavily in 4G as they focus on their customer experience and strengthen their networks to handle the growing data demands. So all that is really constructive in terms of what's happening in the U.S.
landscape. When you look at T-Mobile, in particular, their deal comes with pretty significant buildout requirements. So they've said that they're going to spend $40 billion over the first three years, build an additional 10 to 15 sites, particularly in some of the rural areas where they're expected to cover 97% of the population on low-band spectrum, about 75% on mid-band spectrum within three years. So they've got an awful lot of work to do.
They're certainly going to be deploying capital. So we continue to believe that it's been in their best interest and good for our shareholders as well, to the extent that we can enter into an arrangement where they can have quick access to our sites and potentially renegotiating the way some of the churn happens over time. So to spread that potential churn, which is we continue to believe it's in the range of 3% to 4% of our overall property revenues, that's the overlap piece. And we continue to expect that, that could be spread out over
