Hardik, yes, this is Tim. Yes, first of all, I'd say probably a lot of our suburban I would qualify as first string as well. I kind of figured it was infill, kind of city-adjacent, if you will, or urban-adjacent. So our portfolio is pretty, for the most part, located in employment center locations. So it is where there is economic activity. It is where the jobs are. It is where the people are.
As we said in the past, we're somewhat agnostic between the suburban infill and urban. We kind of allocate capital within the markets, trying to look for the highest, best risk-adjusted returns, and that tends to rotate over time. Sometimes, urban gets overdone. Sometimes, suburban gets overdone. And there, we find there are different points in the cycle. Even within a market, there's better bets to make and one over the other, and it's not always one or the other.
So that's really sort of fundamental to our strategy. And if you look over a longer period of time, from just a pure rent growth standpoint, they pretty much track one another. But within the cycle, they oftentimes are -- can run a little countercyclical. I think actually, right now, urban is running at or just above suburban in terms of rent growth. It's the first time we've seen that in 2 or 3 years -- the first time in 4 years, I'm sorry. And while there's still more supply in urban market, it does suggest that demand is a little bit deeper in urban market. So we don't disagree with that. It's just supply has been overdone for the last 4 or 5 years in urban markets, and I think we're just starting to see -- at a point where a lot of the urban submarkets are really starting to catch up and, in some cases, pass some of the suburban markets.
But as Matt mentioned, generally, if you look at just total returns on invested capital, generally, our sweet spot has been kind of that infill suburban. A lot of that, that has to do with it has the best development economics and then very -- it tends to be pretty healthy from a supply/demand standpoint, from a steady -- at the steady state.
