Yeah, I agree with this. It's just so easy to do a quarterly DCF, there's really no reason not to do it. And the reality is for many market participants, the time value of money is less the retail sale, but the time to get permitting, construction, etc. I've done tons of small deals where it was a 1 year to get the point of sale, and I'd have everything sold in the last quarter. In many major cities in the northeast, the demand is huge - but if it's in a historic district, or worse, a conversion of a historic building, permitting alone could take a year.
Maybe there are markets out there where you can just grab a piece of land and throw up some condos without delay, but I'd say it's pretty rare. Even if I knew of such a market, I'd probably put in 1-2 quarters just to be on the safe side.
As well, the DCF, if you do it correctly the way developers use, can incorporate the equity return rate, which is what market participants care about.
I personally hate condo reports where they do a gross sellout, deduct construction/conversion costs, and put in an entrepreneurial incentive as no developer does that.
