Answer
Why would a small multifamily sponsor use CRE Build instead of a spreadsheet?
You keep spreadsheet-style control without maintaining formulas. Start from a template, then type over any input, or switch an expense line to another method or a custom formula. Every changed line is flagged and shows who changed it, the day and why. One engine computes every figure, and Excel export gives you a snapshot whenever someone asks.
Answer
How do I get my deal into CRE Build?
Start from a multifamily template, either with the product defaults or from scratch with none of its line items, then import your rent roll or unit mix from .csv, .tsv or .xlsx. There is no full-workbook import. The first time, a first-deal tour walks you through the sections.

Comparison
Your spreadsheet vs cre.build
| Job | Your spreadsheet | cre.build |
|---|---|---|
| Change an assumption | Edit a cell; an inserted row can leave a total summing the wrong range, with no record of what changed. | Named line items: Default, Hardcode, Alternate method or Custom formula on expense lines, a custom formula on budget lines, and a ◆ flag on every line you take over. |
| See who changed what | Compare file names and track changes by hand. | Deviations with Who and why, and Versions › Compare with IRR impact. |
| Size the loan | Build each test yourself. | Sizing tests with the binding constraint named. |
| Share with a lender | Email the workbook and wait for comments. | A private copy they work in, with a proposal sent back. |
| Get the numbers out | It's already a spreadsheet. | Reports from the current version, and an Excel snapshot. |
