I know this got a tax break, but how much revenue will it generate once completed?
It got more than a tax break... it's BRA property because the eminent domain taking happened. Type 1 Franklin St. into City assessing page and you'll see.
That said, isn't it "merely" a question of:
--the annual property tax generated by all 450 condo units
--any new state and federal income taxes generated by incoming residents having to declare Mass. residency and/or US citizenship, with attendant tax liabilities
--the mortgage interest on all the mortgages that have been originated, and the economic multiplier effect from that income being spent by the mortgage co. employees
--the income taxes paid by all the construction workers, and the economic multiplier effect from some of their income being spent at nearby businesses
--the income taxes paid by all the condo salespeople and any other similar agents retained by the developer, and the economic multiplier effect of some of their income being spent at nearby businesses
--the economic multiplier effect from all the residents' disposable income that will be spent at nearby businesses
--the income tax paid by all building management/concierge/etc., and the economic multiplier effect from them spending their wages at nearby businesses
--the annual alcohol, sales, business taxes to be generated by the sushi restaurant
--the income tax paid by all sushi restaurant employees and their economic multiplier effect from them spending their wages at nearby businesses
--the annual alcohol, sales, business taxes to be generated by the Roche Bros. annex and the health club
--the income tax paid by all Roche Bros. annex and health club employees and their economic multiplier effect from them spending their wages at nearby restaurants
The property taxes alone will probably average $20k/yr (assuming $1.75 million average condo value) x 450 units equals $9 million.
So even after the construction workers and mortgage loans related income finally tapers off... who knows? As you can see, it's both a massive massive number and a number that is open to widely divergent projections based on how you calculate economic multiplier effect...
