How much an apartment sold for?

ACRIS has co-op sales from 2004 on. For 2003, get the spreadsheet at http://www.nyc.gov/html/dof/html/property/rolling_sales_data_annualized.shtml. For 2002 and earlier, ask the managing agent or a broker who knows the building.

Thanks. How do I use ACRIS to find a 2010 individual apartment sale price once I've got the BBL?

Do you have an insider account on SE? Shell out $10. Pretty easy.

On the Results page, change Max Rows to 99 and scroll through the 2010 transactions. Look at anything with a likely amount to find the sale.

If the sale's not there, it may have been recorded under the wrong BBL. You'd then have to look at all the UCC1s and UCC3s to get a party name. Then you can search on that to find the sale and amount.

The 2010 dates in ACRIS that show a significant dollar amount occur before the StreetEasy sale date (9/2010). Does this matter? Otherwise, the next date of significant dollar amount on ACRIS is in March, 2011, a good 6 months after the Streeteasy sale date. Could this be it? I do not know the names of the buyer/seller.

Sales can be recorded months later. I saw one last week from 2009. You just need to look at everything until you find something with the apartment number you want.

Note that SE can show a place as being sold that never was. E.g., the listing broker may have wanted to flag it as no-longer-on-market but made it Sold in error.

So really, what you're saying is that the most certain method is to go through each large-dollar-amount document on ACRIS and find the correct apartment number?

Yes. Unless the co-op is enormous, there won't be that many 2010-2011 closings to go through.

OK, I went through all the listings, opened up each IMG file for any large-number (price) document. The apartment I am looking for was not found.

Is there any way to find this price, NWT? It's not a big co-op (about 300 records on ACRIS), but nothing with a large number that is the apartment I'm looking for.

Either it didn't sell, or the sale wasn't recorded with the city, or it was recorded under the wrong BBL.

If it sold but wasn't recorded, then transfer taxes weren't paid and penalties are adding up. We can discount that possibility.

If it was recorded under the wrong BBL, then you need a buyer or seller name to search on. To get either of those names you have to work backwards, looking at all the UCC filings in that co-op, until you find a recent one for that apartment. If the seller had borrowed against her shares to buy the thing, then there'll be a UCC3 when she paid off her loan. If the buyer borrowed, then there'll be a UCC1.

Since you're not willing to tell us the address, those're your options.
