Most teams spend days sizing 9% tax credits. Watch me do it in minutes. Sizing a 9% LIHTC (Low-Income Housing Tax Credit) deal means running the same math over and over. You pull the development budget, you strip out land and other costs that do not count. You find the share of low-income units. You multiply by the credit rate. Then you do it again for the next deal. The process is complex and lengthy, that is not my opinion. The Congressional Research Service says the process of allocating, awarding, and claiming the credit is complex and lengthy. The 9% credit is also competitive. States hand out a limited amount each year. Here is the math in plain words. The annual credit is the qualified basis times the 9% rate. Qualified basis is the eligible basis times the applicable fraction. Eligible basis is the total development cost minus the items that do not count, like land. The applicable fraction is the lower of the share of low-income units or the share of low-income square footage. The credit is claimed once a year for 10 years. Some sites get a 30% boost. These are called qualified census tracts and difficult development areas. A simple example: a $1 million qualified basis at 9% gives $90,000 a year in credits, or $900,000 over 10 years. When you size manually, you move slow. Slow sizing makes you miss good deals, because the window to say yes closes while you are still in the spreadsheet. That is the problem and here is the fix. I built a ready-made 9% LIHTC sizing sheet. It runs the full chain for you: eligible basis, applicable fraction, qualified basis, annual credit, 10-year total, equity proceeds, and a sources equals uses balance check. You upload your deal documents, and it shows the math step by step. It runs in a single chat with any AI assistant. You still check the numbers, the tool just does the heavy lifting. This is for affordable housing developers who want to say YES or no faster. If you size 9% deals by hand, this workspace can save you days on every deal. Watch the video below.
