Independent pre-offer analysis for investors acquiring 5 to 100 unit multifamily and mixed-use properties. The calculator is only as good as the data you feed it. We verify the data first.
Most multifamily buyers open the offering memorandum, copy the stated NOI into a calculator, get a green result, and move forward. The calculator does exactly what it's supposed to — it just had bad data going in.
A management fee understated by $60,000. A vacancy rate listed at zero. A property tax figure that predates a reassessment year. Deferred maintenance that doesn't appear anywhere in the expense stack.
"By the time a buyer finds these issues, they are either walking away from a deal or negotiating under pressure. We find them first."
