Simplicity Meets Power in Development Feasibility Software
What is Develop & Sell?
A "Develop and Sell" scenario in real estate development refers to a project where the developer builds properties with the intention of selling them after completion, rather than holding them for long-term rental income.
This approach focuses on maximising short-term profit from the sale of the properties once they are built, rather than generating ongoing operational income from leasing.

Input Screens At A Glance
[M1] Project Settings
Select applicable GST or VAT percentages, or choose "not applicable" to disable them. Customise your company details, logo, currency, and units of measurement. Define up to 7 project stages, or group them into broader categories like Land Acquisition, Soft Costs, and Hard Costs. Set COGS, Revenue, and Other Income Account Heads to categorise project income and costs for reporting purposes.
[M2] Cost Codes
Think of Cost Codes as detailed cost centres that fall under Account Heads for reporting purposes. For example, Drawings & Consultants can be one of your Account Heads, and Architectural Drawings and Engineering will be two different Cost Heads under Drawings & Consultants. You can also specify whether each Cost Head includes or excludes GST/VAT, if applicable.
[01] Dashboard
The Dashboard is designed for simplicity, making it incredibly easy for anyone to use, no matter their experience level. It’s your project’s control center, where you can seamlessly manage all key project assumptions in one place. Effortlessly plan your project with a built-in Gantt chart, input land, construction, and mezzanine finance details, and specify the residential and commercial units you're developing. You can even manage investors and their percentage share holding—all from one simple, intuitive interface that puts complete project control at your fingertips.
[02] Development Costs
The Development Cost section is designed to be simple and intuitive, making it easy to create detailed budgets. All your previously specified Account Heads and Cost Heads come into play here.

Easily allocate when these costs occur, select their stage, and choose whether to project cashflow in a straight line or an S-Curve. You can even adjust the S-Curve's steepness from 1 (least steep) to 10 (most steep). To streamline your workflow, construction costs are automatically pulled in from the residential and commercial units tab, minimizing manual input and preventing duplication.
[03] Interim Income
Interim Income is the revenue a developer can generate from an acquired site during the development and construction phase. Whether it's by collecting rent, selling chattels, or utilizing other site resources, this income helps offset project costs and boosts profitability.
By leveraging Interim Income, developers can reduce their total project expenses, accounting for this crucial revenue stream up until construction completion, ensuring a more accurate and financially efficient project forecast.
[04] Residential Units
The Residential Units section is designed to be super simple and intuitive. Just enter the number of units, their sizes (if available), construction costs, and selling costs. We even pre-fill most details for you, but you can go as granular as you like.
Input construction costs & selling value by per SF/m² rate or per unit rate, and easily manage sales commissions—whether individually or split for pre-sales. You can also select different start dates for each unit or group similar units into one line item. It’s designed to be easy and flexible, giving you full control without complexity.

Game-Changing Highlights That Make
Lead Developer Unstoppable
Project Planner
Planning your development feasibility with Lead Developer’s project planner is essential for understanding when costs occur, when funding is required, and when the project is expected to be sold.
With a built-in Gantt chart, it offers a visual representation of your entire project timeline, helping you map out key stages like land acquisition, interim income, construction, funding and unit sales. This visualisation aids in planning equity and funding needs, ensuring the developer remains financially prepared and avoids running out of resources midway through the project.
Funding Options | Capital Stack
Lead Developer offers a powerful, flexible funding solution with five distinct capital tranches that can be seamlessly integrated into your project’s financing, balancing debt and equity to suit your needs:
- Land Acquisition Loan: perfect for securing land or purchasing a site specially when there is a gap between buying the land and starting construction or renovation. Choose from principal + interest or interest-only loan options, with the flexibility to select either fixed or variable interest rates as well as whether you wish to capitalise the interest payments or not.
- Construction Loan: Activated once the project is construction-ready, this loan can also cover the Land Acquisition Loan, allowing for smooth transitions before breaking ground.
- Mezzanine Loan: A strategic interim loan designed to cover any equity shortfall, providing an additional layer of financial flexibility.
- Developer's Equity | General Partner (GP): Represents the sponsor's or developer's contribution to the project, demonstrating their vested interest.
- Investor's Equity | Limited Partner (LP): The external investor’s capital, typically contributing to the equity stack and partnering with the GP.
- Cost of Developers / Investors Equity: You can even account for interest on developer's & investors equity separately with different interest rates that get paid out post senior and junior loans are paid out.
What makes Lead Developer's platform truly exceptional is its flexibility— you can not only customize interest rates and setup costs for each loan, but also control the order of drawdowns. Choose whether debt or equity is drawn first, or fine-tune the sequence within each category, such as drawing from the Construction Loan or Mezzanine Loan first.
On the equity side, decide whether the GP or LP funds are utilized first, or opt for pari passu, where they are drawn proportionally. This advanced configurability gives you unmatched control over your project’s financial structure, ensuring you can optimize for both risk and return.
Funding Table
A funding table is a critical component of development feasibility as it outlines the various sources of capital and debt used to finance a project. It breaks down the financing structure, detailing how much of the project will be funded through equity (from the developer or investors) and how much will be covered by loans.
By mapping this out in advance, developers can accurately gauge funding needs, ensure financial stability, and avoid potential cash flow problems as the project progresses. This table is essential for determining how and when different funding sources will be utilized, optimizing the project’s financial strategy.
Funding Options in Lead Developer
Lead Developer provides five versatile options to size your construction loan, allowing you to determine the maximum debt for your project:
- Loan to Cost (LTC) Based on Hard Costs or Total Costs as determined by your lender: This option helps you secure a loan based on hard costs (such as construction), providing a more conservative and structured approach to borrowing, especially for banks that only consider hard costs & only selected soft costs in their lending criteria.
- Loan to Cost (LTC) Based on Total Project Costs: Typically used by banks, this option allows you to secure a loan based on the project’s total costs. Lead Developer lets you break down each cost item, deciding whether it qualifies as a hard cost to be included in the bank’s LTC calculation.
- LTC Based on Total Sales: This option allows you to secure financing based on the projected sales revenue, giving you flexibility in structuring your loan around future income.
- Max Debt - Manual: For situations where you know the maximum debt you can borrow, this option allows you to input a manual limit.
- Max Equity - Manual: If you already know how much equity you can contribute, Lead Developer lets you set the maximum amount for the project.
These options are crucial because they provide customizable ways to size your construction loan based on different financial scenarios. Lead Developer makes it simple by offering a streamlined, adaptable approach to fit your project's unique requirements, ensuring you're able to balance debt and equity while avoiding over leveraging.
Cost-Loading Development Costs /
S-Curve Distribution
In real estate development, cash flow management is critical, and properly forecasting development and construction costs is a key part of this. One of the best methods to project costs over time is through S-Curve aka Bell Curve distributions, which help to distribute cash outflows more realistically over the project’s lifecycle.
Instead of assuming equal expenditures every month, an S-Curve reflects the natural flow of a project, where costs are typically lower at the beginning, accelerate during peak phases, and taper off towards the end.
The S-Curve distribution is important because:
- It helps developers determine monthly outgoings, ensuring accurate cash flow planning.
- It allows for precise calculation of developer's equity needs, as the equity must be available at the right time.
- It enables the calculation of interest costs, as interest is only charged on the funds that have been drawn down, not on the entire loan amount.
Lead Developer simplifies this process by allowing you to distribute project costs dynamically using an S-Curve distribution. Whether you're projecting development, construction, or other costs, Lead Developer makes it easy to adjust for real-world cash flow fluctuations.
In Lead Developer, you can even choose the steepness of the S-Curve, selecting from a scale of 1 to 10. A flatter curve (1) means slower cost accumulation, while a steeper curve (10) accelerates costs rapidly. This flexibility is crucial because not all costs are incurred at the same rate—some expenditures peak early, while others might occur evenly throughout the project.
By using Lead Developer’s S-Curve distribution functionality, you gain the ability to forecast costs accurately, manage your cash flow, and avoid surprises. Lead Developer puts you in control, making advanced financial modelling accessible for everyone, ensuring your project cashflows are correctly projected from start to finish.
The Loop That Breaks Excel, But Powers Your Feasibility
This is the kind of complex feature that breaks Excel, but we've built it seamlessly into Lead Developer.
Total Development Costs (TDC) include everything, even finance and interest costs for construction. In fact, banks require interest costs to be factored into the total development costs also known as interest reserve.
Interest Reserve
An interest reserve is a financial tool often used in real estate development or construction loans to cover interest payments during the project's construction phase. Instead of the borrower making regular interest payments out of pocket, a portion of the loan is set aside in a reserve account to pay the interest as it accrues.
This allows the developer to focus on the construction without worrying about servicing the debt until the project generates income, typically once it's completed, leased, or sold.
Here’s how it works:
- Loan Structure: When a lender agrees to finance a development project, they include an amount in the total loan to cover interest expenses during the construction period.
- No Immediate Payments: Instead of requiring monthly interest payments during construction, the lender draws from the interest reserve to cover these costs.
- Self-Adjusting: As the project progresses, the loan balance increases because the unpaid interest is capitalized, meaning it gets added to the principal balance.
- Transition to Regular Payments: Once the project is complete or reaches stabilization (e.g., occupancy for lease-up projects), the borrower starts making regular payments, including principal and interest, based on the full loan amount.
The interest reserve helps ensure the project has sufficient funding and allows the developer to focus on completing the project without worrying about cash flow to cover interest.
Here's where it gets tricky
Interest is calculated on your maximum debt, determined by the bank’s loan amount. But the maximum debt itself is based on the bank’s loan-to-cost (LTC) ratio, which is a percentage of Total Development Costs. This creates an infinite loop, requiring multiple iterations of calculations to pinpoint the correct amount.
Attempting to code this in Excel can cause serious headaches (trust me, we’ve broken many spreadsheets trying to do it!). But you don’t need to worry because Lead Developer Feasibility Suite handles the hard part.
✓ Our software runs numerous iterative calculations in the background, fine-tuning interest and debt figures until the most accurate interest cost is selected for your project.
This advanced, iterative calculation is built into One Minute Feaso, Smart Feasibility Calculator, Lead Developer & Lead Developer+. It’s a level of precision and automation that DIY spreadsheets simply can’t achieve, and it’s one of the key reasons why Lead Developer Feasibility Suite outshines anything else in the market.
Since 2012, I’ve spent my own time and money finding, stacking, and executing property development projects—constantly checking them against my feasibilities and tracking results. I’ve gone through thousands of iterations to refine the process, and now, I’ve packaged it all into a property development feasibility software. These tools were the missing piece of the puzzle I needed to make confident development decisions when I was starting out.
Lead Developer is a powerful, detailed financial feasibility software. It gives you the ability to plan and distribute cash flows using an S-curve, create custom cost heads and codes, and explore multiple financing options. It’s everything I wish I had when I began my development journey, and now it’s all in one place for you.
