Construction Draw and Interest Calculation Model

Sources and Uses

I’ve been meaning to include this equity/construction loan draw and interest calculation tool in our library of real estate financial analysis models, and finally got around to uploading it today. I built this awhile back at a time when I was working to improve my cash flow modeling skills. Complex cash flow tracking, as is often the case when modeling development cash flows or equity waterfalls, is a learned skill best acquired through practice and repetition (like most things!). So I chugged away for quite some time at this basic model to practice, and it has since turned into a viable analysis tool.

Since completing the first iteration of the model earlier this year, I’ve cleaned up a few errors, added more budget line items, included a few graphs to visualize how the sources and uses flow over the construction period, and dropped in s-curve forecasting capability – a technique I blogged about a few weeks back.

Using the Construction Draw and Interest Calculation Model

The model includes a sources and uses tab and budget tab for inputs. It also includes three calculation tabs: an interest calc tab, s-curve calc tab, and raw data tab for data validation lists. The construction interest calculation avoids a circular reference, which is pretty cool. And I used dynamic named ranges, another topic I wrote about a few posts ago, to make the graphs dynamic to changes in construction length.

Check out the expanded video tutorial I created for this model.

Download The Model

To make this model accessible to everyone, it is offered on a "Pay What You're Able" basis with no minimum (enter $0 if you'd like) or maximum (your support helps keep the content coming - typical real estate models sell for $100 - $300 each). Just enter a price together with an email address to send the download link to, and then click 'Continue'. If you have any questions about our "Pay What You're Able" program or why we offer our models on this basis, please reach out to either Mike or Spencer.

Note (especially for Gmail users): The model is sent via email and occasionally is blocked by spam filters. If you don't see the email arrive within five minutes, check your spam folder.

Updates to the Model

UPDATE: Version 1.2 includes budget timing alerts and a fix in how Length was calculated in column F of the Budget tab. Also fine-tuned the error check to hopefully eliminate a few false error alerts that were occurring.

UPDATE: Version 1.31: added calculation for construction loan fees (origination fee, points, etc), and made color scheme consistent across charts.

UPDATE: Version 2.0: added a Gantt chart tab that automatically visualizes the construction timeline

UPDATE: Version 2.2: moved the S-Curve calculations to columns EG:GV of the Budget tab to make it easier to add/delete budget rows
