Answer
What is CRE Build?
CRE Build is multifamily deal modeling software that runs in your browser. You start a development or acquisition deal from its own template, type over any input or switch an expense line to another method or a custom formula, size the loan on every lender test, and share a private copy with your lender or partner by email.
Answer
How is CRE Build different from building a model in a spreadsheet?
You keep spreadsheet-style control without building or repairing formulas. One calculation engine computes every figure, lines you take over are flagged with ◆, and construction interest is solved together with total cost, with no circular references. When someone needs Excel, you export a snapshot; the model itself recalculates in CRE Build, not in the workbook.
Answer
Who is CRE Build for?
It’s for sponsors and underwriters modeling multifamily acquisition and development deals who want spreadsheet-style control and want to see which numbers they’ve changed. Share a private copy with your lender or partners, and their changes come back to you as proposals.
Answer
Who is CRE Build not for?
It’s not a broker CRM, a property-management system or appraisal software. If you need to manage listings or run property operations, this isn’t that product.
02 · The problem
Insert a row. The math still points where it should.
A downloaded deal model is someone else’s logic. Insert one row and the tax line can sum the wrong range, with no record of what changed.
In CRE Build every line item has a name, not a cell address. Lines you take over are flagged on the line, and the model flags problems on the section where they occur.
03 · Defaults and control
The template said $462,579. The reassessment says $664,947.
Real estate taxes on a Charlotte development aren't $1,450 a unit grown at 3%, which comes to $462,579 in the stabilized year. They're millage on the value the building carries once it stabilizes: $664,947, or $202,368 a year more than the template. Take that line over and levered IRR drops 1.4 points, from 13.4% to 12.0%.
Default
The template's method. $1,450 per unit, grown with expenses.
Hardcode
Your number, in your unit: $/unit, $/SF, % of EGI, lump sum, growth rate.
Alternate method
From the library. Reassess at stabilization: millage × assessed % × value at stabilization.
Custom formula
On expense and budget lines: a fixed subset of Excel syntax over named variables, read back as how and when it's computed.
Expense lines take all four. Budget lines take a stated amount or a custom formula. Any other input you change is flagged on the line.
04 · Features
12 capabilities, one multifamily model
Grouped the way a deal moves: Model, Capital, Decide and Workflow.
Model
Every section of a multifamily deal, budget and draws, and line-item control.
Capital
Loan sizing with the binding test, the equity waterfall and market rates.
Decide
Returns, sensitivity, scenarios, reports and Excel export.
Workflow
Pipeline, sharing and lender review, versions, account and data.
05 · Pipeline
Every deal, from sourcing to closed
Track every deal next to its model: board, table and map over one list, with filters and saved views. Once a deal is underwritten, its card shows IRR and equity.

06 · Share and propose
Share a private copy. Get changes back as proposals.
Share a private copy with your lender, equity partners or a teammate. They work in their own copy and send changes back as a proposal: the terms they're offering and the underwriting they dispute, each priced for you. They can't change your model; you accept or decline. People you share with sign up free and get Pro.

Step 2 · Proposal
Step 3 · Sender

07 · Exports and trust
Take your numbers to Excel
Take any version of your deal to your lender, partners or investment committee in the format they already use. Export any version to Excel as a snapshot of CRE Build's figures: annual totals on the Operating statement are SUM formulas; other cells are values. The model itself recalculates in CRE Build, not in the workbook.
