“During my 10 years in commercial and residential development, I've worked with a ton of proformas. Discovering TILT's model felt like finding the Holy Grail of development proformas. The level of detail and sheer power of various residential and commercial scenarios within the TILT model is truly mind blowing! I have truly never seen anything close to what Justin's model can do. Also invaluable is Justin and his team's availability to do custom, a-la-carte, project-specific tweaks to the proforma. Equally impressive are the investor/lender-facing summary sheets, which are easy to understand and visually impeccable.”

Frequently asked questions
The model
What is a residential development pro forma model?
It is a financial model for a ground-up residential project. It forecasts rent or sale revenue, construction costs, financing, and returns from land purchase through stabilization or sale. The TILT model supports up to 40 unit types.
What's the difference between a development model and an acquisition model?
A development model covers a project you are building, including land, construction costs, loan draws, lease-up or ramp-up, and stabilization. An acquisition model starts with an existing property and its current rent roll or operating results.
Is the model a downloadable Excel file?
Yes. It is a macro-enabled .xlsb Excel workbook that you download and run on your computer. Nothing runs in the cloud, and your files stay local. The license covers your company rather than individual users.
Does this model handle multifamily, single-family, condos, and townhomes?
Yes. It handles multifamily, single-family detached, single-family attached, condos, townhomes, build-to-rent, and stacked product. You can combine them in one project.
Can the model handle both for-sale and for-rent residential?
Yes. For-sale projects use absorption schedules, deposits, and sales-velocity inputs. For-rent projects use unit mix, rent, concessions, vacancy, and operating expenses. You can also sell some unit types and rent others.
How many unit types can I model in one project?
Up to 40 unit types. Each type can have its own square footage, unit count, rent or sale price, expenses, and exit assumptions. There is no limit on the number of units in each type.
How many development phases can I model?
Up to 20 phases, in series or in parallel. Phase timing controls cost spending, loan draws, and revenue start dates.
How is this different from a free residential development template?
Free templates are usually built for simple deals. The TILT model supports rental and for-sale projects, phased development, construction financing, optional financing add-ons, and partnership waterfalls. It also includes setup help and technical support.
Financing & structure
Does the model handle construction loan draws and interest?
Yes. The model tracks monthly draws, interest accrual, and payoff timing without circular references. You can size the loan by LTC, a dollar amount, stabilized DSCR, or percent of stabilized value.
What's the difference between sizing a construction loan by LTC and by DSCR?
LTC sizes the loan as a percentage of total project cost. DSCR sizes it based on the debt service the stabilized property can support. The model supports both methods.
Does the model handle C-PACE, TIF, LIHTC, and other complex financing?
Yes. Optional paid add-ons include C-PACE, TIF, LIHTC, mezzanine debt, and multi-date exit. The model also supports grants and separate land and construction loans.
Does the model handle GP and LP waterfalls?
Yes. You can model up to 6 LP investors and 6 GP sponsors with preferred returns, IRR hurdles, and promote splits. The results flow to the deal summary and investor cash flow sheets.
Buying & support
How much does the model cost?
Pricing includes a base model and any optional features your project needs. The license covers your company rather than individual users. Use the form below to request a quote.
Can you help put my project data into the model?
Yes. TILT can enter your cost budget and other project inputs on an hourly basis. Your project information stays confidential.
What if my project later expands to include commercial or hotel uses?
You can upgrade to the mixed-use version and add commercial or hotel uses when you need them.
How often is the model updated?
The model is updated throughout the year. A full annual renewal includes features added during the year. Contact TILT for current renewal options.
What if I need a feature the model doesn't have?
TILT can add a financing structure, output sheet, or waterfall for an hourly fee.
Can TILT work with us beyond the model?
Yes. RE Analyst services can help enter project data, review underwriting, prepare offering memorandums and investor decks, and build custom models. Work is available by the hour or on retainer.
What's included after I get the model?
Each model includes up to one hour with Justin. You can use 15 to 30 minutes before buying to review your deal structure. That time counts toward the hour, and you can use the rest to set up your first project. Ongoing technical support is free. Project input and analysis are available by the hour.
What do I need to run the model?
You need the 64-bit Microsoft 365 desktop version of Excel on Windows or Mac, with macros enabled. Do not use Excel for the web because its macro support is limited.
