Juan, it's Dave. Let me start with the acquisition landscape as we see it. We, in the first quarter, underwrote or received tapes. And I'm going to break this down into 2 components, that the national builder and existing homes.
So starting with the national builder side, we received tapes in the first quarter. It contained more than 35,000 homes, about 15,000 or a little over 15,000 of those are in our markets. We analyzed those. And we analyze them based on location, quality, what the type of asset is. We're looking for detached homes, and then, obviously, get down to price and yield.
What we were seeing in the national builder side is those that would be in the location and quality that we desire. They're in the high 4s, maybe some in the low 5s on an economic yield. On a nominal accounting yield, probably add 10, 20 basis points to it. We would need 15%, plus or minus, decline in the transaction price at the current landscape of rents, et cetera, to make those deals work.
Moving over to the acquisition. We are seeing a significant reduction in the supply of new homes in our markets. This is not a new story. This is a story that's really been playing out since COVID started. So we're about half -- in our top 20 markets, we see about half of the number of homes that we saw pre-pandemic.
Pricing. We haven't seen any significant reduction in pricing, a little bit in a couple of our markets, mainly Midwest. And again, the way we underwrite on economic yield, those are in the high 4s, low 5s. We might have ability to sharp shoot a property here and there. we're seeing a little bit of opportunity coming into the 5. So we'll see how that plays out.
Portfolios. Again, on the portfolio side, it's kind of the same as the acquisition of the existing homes. On development, high 5s on economic yields, add 10, 20 basis points, gets you around 6% in that area on a nominal NOI basis.
