You're right except I think it's the other way around: density is a response to demand, not the driver of it. It might depend whether you mean "density" = the population that desires to live and work in a given area; or "density" = the
population that lives and works in a given area. I tend to think of it as the latter.
Price = demand/supply ~ish, and when a lot costs $8M, the only sensible thing to do sometimes is invest $40M in construction, and sell 200 condo units for $0.5M each (totally pulling these numbers out of my ass but you get the point).
That's the simple version, but in real life there are a lot of externalities and a place that's good for a SFH might not be good for an apartment &vv. For instance, would you want a train or busy road right out your front door? No. But you might not mind it 20 stories up. Maybe you could even find a tenant for the main floor who actually LIKES busy roads, the way some businesses might. There's not a neighbourhood in Calgary that doesn't have room for more people and businesses, and when the density increases, it's not causing property values to rise, it's
because of it.
Asterisk: Does density have an effect on property value. Yes, of course it does. Is the effect the same for every use? No, of course it isn't. Ideally, when more condos go into a neighbourhood, they bring with them more retail, better services, and maybe they improve that dead corner that has been a dusty parking lot without sidewalks. If all goes well, this new development will increase the value of the rest of the neighbourhood. BUT, unfortunately, as much as I wish it weren't the case, I think historically, with poor planning, there are plenty of examples of increasing density that had a negative effect on property values of SFHs. Mid-century Eau Claire is a good example where there was inflexible zoning, perceived crime, racist perceptions of China town and FN, increased hegemony of other neighbourhoods on its land use, decreasing nighttime population. Maybe this is actually an example of the effect of decreased density in that case...
Anyway, I think property value affects density, and density might affect property value in different ways. What really matters to city building is the public efficiency to tax and service communities with transit, safety, education, health, and things that make us happy. It's a lot easier to sustain achievement of this goal in a relatively-dense (by Calgary standards), diverse neighbourhood with limited barriers (simple, elemental zoning rules; inclusive social attitudes; accessibility) and more choice (multimodal networks; housing/employment/service options).
Or, we could just subsidize sprawl and pass a gargantuan debt of inefficiencies and social problems to another generation while the cost of living increases and quality of life plateaus.
