Well I'm not so sure about this one...
Taking a quick look at the numbers in the Schedule, they used an example of a property with a current assessment of $5,000,000 and a future assessment of $42,000,000. After investing that $37,000,000 in additional monies to complete the project. This program would then provide a stabilized rebate on future property taxes of $160,000 per year for 10 years.
That $160,000 per year represents an additional "return" to the developer of 0.43% on his incremental investment. In exchange for that, the developer needs to front end all of the development costs and accept a minimum $78,000 in reduced rents (assuming all units are one bedrooms as the "qualifiers" for others are not apparent) to qualify for that rebate - roughly 0.21% of his incremental investment. The net return to the developer from this program is therefor 0.22% for which he is expected to cede project control of 40% of his project and incur his accounting a reporting costs to participate.
In my experience, new development projects don't proceed or not proceed on the basis of a 0.22% incremental return. So, unless I'm missing something, this is an ongoing program that the city needs to administer - which won't come for free - for some 14 years or longer that won't actually increase the housing stock that would be developed without it.
If I'm missing something here, I'd be happy to know what it is...
