Incentive property classes & their assessment rates

[AleaWM]

Is there a data source that has the assessment rate used for incentive properties in each tax year?

Incentive properties have their assessment rate change over time so backing out the market value of the property is not easily or accurately done. The Assessed Value and EAV are included in PTAXSIM, but without the assessment rate in a given year for these property classes, can the market value be calculated?

A CSV file of PIN level data for properties (PINS or parcels, either would be great) with 600 and higher property classes with the tax year and assessment rate would be appreciated!

@AleaWM I've been wondering this myself as I recently wanted to back out the market value of all properties (which indeed requires the assessment rates of incentive properties). I believe we have this data for recent years but getting it for the full time covered by PTAXSIM is challenging. I'll ask around. If we do get it, I'll likely add it as an additional table OR add a market value column to the pin table.

@dfsnow very understandable, and thank you for the quick response! Is there someone I can contact for just the 2021 assessment rates in the form of a separate file so that I could merge it in myself?

@AleaWM So, the current levels of assessments for incentive properties seemingly do exist in the system of record. However, considering that we (the data science folks) have never had to retrieve them before, it's going to take us awhile to write an accurate query to do so.

Unfortunately, it's modeling season right now so capacity is pretty limited. If you need these values quickly I recommend submitting a FIOA request, since they might be more practiced in retrieving these values.

It isn't urgent so I will wait a little bit to do a FOIA request, thanks for the link and tip. I do know that the assessment rates of incentive properties (or something indicating where they are in their rate phase out and market values) would be very appreciated. Thank you!
