Building on yesterday's post about inclusionary zoning, below is a telling diagram from the Urban Land Institute showing which areas of Portland can support new development and which areas cannot. To create this map, ULI looked at achievable rents in each US census block to determine, quite simply, where rents will cover the cost of new development (all types of construction).

However, in their models they are also assuming a land value of $0. And typically people want you to pay them money when you buy their land. So in all likelihood, this map is overstating the amount of blue -- that being land where new development is feasible.
But it does tell you something about developer margins. A lot of people seem to assume that the margins on new developments are so great that things like inclusionary zoning can simply be "absorbed" without impacting overall feasibility. The reality is that there are large swaths in most cities where development is never going to happen even if you were to start handing out free land.
This map is also helpful at illustrating some of the impacts of IZ. If you assume that rents are the highest in the center of the city and that they fall off as you move outward, then the outer edge of the above blue area is going to be where development is only marginally feasible. And so any new cost imposed on development would naturally start to uniformly eat away at the blue feasible area -- that is, until rents rise enough to offset it.
Of course, this is a simplified mapping. Land usually costs money. Land values might also be highest in the center and fall off as you move outward, or there could be pockets of high-cost land. There may be more price elasticity in certain sub-markets compared to others. So the impacts of a new development cost may not play out as neatly as I outlined above.
Regardless, there will be impacts, which is why I find this map telling even if it isn't fully accurate or up to date. Maybe some of you will as well.
If you've bought land with the intention of developing it and you now think the value of that land has either gone up or down, there comes the question of what number you should plug into your development pro forma. Do you input what you paid for the land or do you input the current market value of the land? The former is probably more common than the latter, but in my view it's important to consider both scenarios.
If the value of the land has gone up, it means that you think you could turn around and sell it for that price today. And that would mean you would be making a profit without doing anymore work and without taking on any additional risk. That's an option that exists right here and right now (t = 0). What you want to get at in your pro forma, or at least understand, is the incremental profit margin from taking on the risk and brain damage of actually doing and completing the development project.
To do that, you need to consider the current market value of the land. That way you isolate your land margin from your build-out margin. The one problem with this approach is that the numbers may then tell you not to develop. In a hot market (which is not right now), it is not uncommon for land to get bid up beyond current fundamentals. There's always someone else who is willing to be more aggressive.
In this case, you may find that most of the development margin is in the land. And you will start thinking to yourself, "How can anyone afford to pay this much? It doesn't make sense." This doesn't necessarily mean that you shouldn't develop. But at least it gives you a better understanding of the risk and reward trade-off that you're about to take on. It might also tell you some things about the market.
