I'm not sure if they are able to get closing done tower by tower. If they are, then the people in 65 may not have to wait too long to get closing. But I would assume that they are doing the closing on the entire project at once. If that's the case then people will be paying occupancy in 65 for up to a year it looks like.
I think a lot of people are misinformed about occupancy. It's actually not all that big of a deal. What they do is they take an estimate of what your monthly taxes and maintenance fees are, add in the interest you owe on the loan, and that's what you pay. So let's say you buy a condo for 300 grand, put 50 grand down. You have to pay interest on 250 grand. The only difference between occupancy and being closed on the condo is the principle you would pay down on the mortgage. If you have occupancy for a year, you are only losing out on the $1200-2000 for the first year's principle. That's because the first few years of a mortgage are almost all interest payments. I don't know why it scares people so much to have to pay it. Besides, you aren't banking on the money you pay down on a loan, you are banking on long term capital appreciation. In 5 years of owning, you might have only paid off 10 grand of your mortgage, but the capital appreciation (in a decent market) would be 5-10 times that.
