Single Family Residential Investment Analysis Model (Updated Apr 2023)
Pre-2008, I bought and sold my fair share of single family homes – both for investment purposes (rental or flips) and to live in. In those days, almost everyone was “investing” in residential real estate – hence the market crash. I personally don’t have any plans to get back into buying and selling homes, beyond my own residence, but I recognize that many of you do. I decided to put together a single family investment analysis model in Excel (also commonly referred to as a real estate pro forma) for those of you who need a model to use when buying homes either to fix and flip, or to fix and rent out.
Note: A partnership waterfall module was added to v3.0 of this model to calculate returns for up to three partners; enhanced forecast of sources of uses cash flows was added in v3.3. See the version notes for the latest changes.
How the Single Family Residential Investment Model Works
The model works with either the fix and flip, or the rental strategy. Using the Assumptions tabs, you input the parameters of your investment, and than check out the results on the Cash Flow and Summary tabs. The model can handle investments that last up to 84 months, details your monthly cash inflow/outflow, and calculates the maximum equity required to execute on the investment. Return metrics include unlevered and levered internal rate of return and equity multiple, cash on cash return, as well as net equity gain with and without financing.
Navigating the Six Worksheets in the Model
Version – See what changes have been made to the model in recent versions.
Assumptions – Most investment-related inputs are entered in this worksheet. These include property description, investment timing, acquisition and investment costs, disposition assumptions, fixed and variable operating expense assumptions, financing assumptions, and rental operation assumptions. It is also on this tab where you will choose between a ‘Hold’ strategy and a ‘Flip’ strategy.
Construction Budget – The second of two input sheets, it is on the Construction Budget worksheet where you detail out the renovation budget by line item. If you aren’t ready to itemize the construction budget, set a global renovation budget in cell D5.
Summary – A summary of the cash flow and returns of the proposed investment are shown on this worksheet.
Monthly Cash Flow – The meat of the calculations are performed on the Monthly Cash Flow worksheet. Assumptions entered on the Assumptions and Construction Budget sheets flow to the Monthly Cash Flow sheet where a forecast of all cash flows, by month, are calculated. Monthly returns on an unlevered (i.e. without debt) and a levered (i.e. with debt) basis are then calculated at the bottom of the worksheet.
Annual Cash Flow – Monthly cash flows are rolled up on the Annual Cash Flow sheet, and then annual returns on an unlevered and levered basis are calculated.
Partnership Cash Flow – Inputs, calculations, and outputs for partnership cash flows. Use this tab to forecast contributions from and distributions to up to three partners to the investment.
Other Real Estate Financial Models to Consider
Since building this model, I’ve put together a few other single-family related models that you might also consider.
- Single-Family Home Construction Pro Forma for Home Builders – For modeling ground-up single family home construction
- Residential Land Development Pro Forma – For analyzing single-phase residential (lot) land development
- House Flip Pro Forma – A robust back-of-the-envelope fix and flip model built in Excel

Video Tutorial of the Single Family Residential Investment Model
For instructions on how to use the model, I recorded a walkthrough video using v1.0 of the model. While the model has since been updated, the core methodology of the model remains the same.
