The Development Feasibility Platform For Volume-Feasibility Teams

Volume feasibility — running feasibility studies on ten to twenty parcels a week — is a specific problem. The traditional feasibility spreadsheet is fine for one parcel at a time; it breaks when the team is trying to compare ten parcels against each other or when the assumptions in the underlying model have to be reused across a portfolio. Volume feasibility needs a platform, not a workbook.

This platform is built for that use case. It carries parcel intake, scenario stacking, sensitivity analysis, and verdict output through one workflow, and it lets a team compare the feasibility distributions across a portfolio in a single view. The distinction from feasibility software is the portfolio-level layer.

What changes when feasibility becomes portfolio-level

At one parcel, the developer wants a detailed distribution and a sensitivity view. At ten parcels, the developer wants a ranked list — which parcels have the highest p50 ROI, which parcels have the highest floor at p10, which parcels have the widest spread. The two questions require different views of the same underlying scenarios. The platform provides both. Single-parcel view is the detailed distribution and sensitivity. Portfolio view is the ranked comparison. The two views share the underlying model — a change to the assumption set propagates to all parcels in the portfolio.

Assumption reuse across parcels

In a spreadsheet the assumption set is copied into each tab and diverges over time. Analyst A's hard-cost assumption on parcel 7 is different from analyst B's hard-cost assumption on parcel 12, and nobody notices until the meeting when the comparisons look inconsistent. The platform maintains one assumption set at the portfolio level and lets each parcel override with a logged reason. This is the invisible efficiency gain. The comparisons across parcels are actually comparable because the assumption set is shared; overrides are visible; the meeting is about which parcel wins on merit, not about which analyst's assumptions were more optimistic.

Scenario stacking, structured

Each parcel has a base scenario and can have up to four alternative scenarios — different program, different quality tier, different phasing, different exit strategy. The platform runs all five scenarios per parcel and displays them side-by-side. This is where the volume-feasibility team spends most of its time. The base scenario is fast; the alternatives are where the analysis actually adds value. A parcel that clears the target return on the base scenario but has a stronger alternative scenario is a parcel with an obvious pivot; the platform surfaces the pivot rather than burying it. • Base scenario + up to four alternatives per parcel. • Shared assumption set with per-scenario overrides. • Side-by-side scenario comparison in one view. • Portfolio-level ranking by p10, p50, or p90 ROI. • Assumption-set changes propagate across the portfolio.

Portfolio-level ROI distribution

The portfolio view stacks the scenario distributions across parcels. What emerges is not a single portfolio number — it is the distribution of parcels by their p50 ROI, and the tail risk represented by each parcel's p10. Principals typically look at both. High-p50, low-p10 parcels are high-upside bets; high-p50, high-p10 parcels are the reliable core; wide-spread parcels are the ones that need more diligence before commitment. This is the analytical layer that turns a list of feasibility PDFs into a portfolio decision. Without it, the principal is comparing PDFs manually and the comparison is dominated by whichever PDF was read most recently.

How this connects to the rest of the platform

Feasibility platform inherits from acquisition (which produced the parcel record) and hands off to pre-development (which builds on the winning scenario). Every scenario logged on the platform is queryable months later; a scope decision in pre-development traces back to the feasibility scenario that justified it. This is the integrated pattern. Feasibility is not a separate exercise done in a spreadsheet and thrown away — it is a versioned decision that participates in the deal record.

A real-world workflow: quarterly portfolio review across 24 active feasibility studies

A ten-person development firm runs 8-12 new feasibility studies per week and maintains a rolling portfolio of 20-30 active studies (parcels in various stages between initial feasibility and LOI). The quarterly review runs on the portfolio view. The principal opens the portfolio view sorted by p50 ROI descending. The top 6 parcels are the LOI candidates for the quarter; the platform surfaces the shared risk driver — 4 of the 6 are in the same submarket and are exposed to the same rent-growth assumption. The principal runs an assumption-set stress test: what if rent growth drops from 4% to 2%. The portfolio view updates in real time; 2 of the 6 fall below target. The result: LOI on 4 parcels, monitor 2 for a rent-growth signal, reject 18 at the current-cycle assumption set.

Implementation guidance for portfolio-level feasibility

Portfolio-level feasibility requires an account admin who owns the shared assumption set. The admin's job is to keep the market-tied assumptions current (cost bands, cap rates, rent-growth), review analyst overrides for consistency, and run the quarterly stress tests. The failure mode is drift in the shared assumption set. If each analyst overrides the cost band on their own parcels, the portfolio comparison stops being apples-to-apples. The discipline is that overrides require a logged reason and are audited monthly; unaudited overrides are the leading cause of portfolio-view inconsistency.

Portfolio construction with the feasibility platform

Portfolio construction is the discipline of choosing which parcels to advance from feasibility to LOI given a finite capital allocation. The platform supports it with a ranking view weighted by capital-per-parcel and by risk category. The pattern: filter the portfolio to parcels within the current-quarter LOI budget, rank by p50 ROI, exclude any parcel where the p10 falls below the firm's minimum-acceptable-return threshold. What remains is the LOI shortlist. The principal reviews the shortlist and approves the deals. The failure mode is chasing the highest p50 without regard to the p10. High-p50, low-p10 parcels are gambles; a portfolio of gambles produces a single loss that wipes out several gains. Disciplined portfolio construction weights the p10 alongside the p50 and produces a portfolio whose worst-case is survivable. • Filter — parcels within current LOI budget. • Rank — by p50 ROI. • Exclude — where p10 falls below minimum threshold. • Approve — the shortlist that survives all three filters.

Use Cases

  • Portfolio-level ranking: Rank parcels across the portfolio by p10, p50, or p90 ROI — the view a principal actually needs before allocating.
  • Shared assumption set: One assumption set at the portfolio level with per-parcel logged overrides — no divergent-workbook drift.
  • Scenario stacking: Base + up to four alternative scenarios per parcel, run side-by-side against the shared assumption set.
  • Portfolio ROI distribution: Distribution of parcel outcomes with tail-risk visibility — the analytical layer above individual feasibility PDFs.
  • Cross-stage handoff: Winning scenario hands off to pre-development with the assumption log intact; downstream decisions trace back to the feasibility justification.
  • Quarterly stress-test view: Change any assumption at the portfolio level and see the portfolio's response instantly — the view the principal runs before allocation decisions.
  • Override audit workflow: Analyst overrides on the shared assumption set are logged and audited monthly by the account admin — the discipline that keeps the portfolio comparison honest.

Frequently Asked Questions

Why choose an integrated platform instead of feasibility spreadsheets?
Spreadsheets do not compare across parcels reliably. Feasibility becomes a portfolio problem once the team is running more than a few studies a week, and portfolio problems need a platform layer.
How does AI improve development planning at the feasibility stage?
By running the scenarios across the portfolio in the same time it would take a spreadsheet to run one, so the team can afford to explore alternatives per parcel instead of committing to the base scenario.
How can investors evaluate parcels faster?
By using the portfolio ranking to focus attention on the top-scoring parcels first and by using the shared assumption set to trust that the comparisons are apples-to-apples.
Why choose an integrated platform instead of feasibility spreadsheets at portfolio scale?
Spreadsheets do not stress-test portfolios. Changing an assumption in one spreadsheet does not update the other 23; the portfolio comparison drifts silently. The platform enforces consistency.
How can Buildora IQ streamline pre-development workflows?
By handing off the winning feasibility scenario to pre-development with the full portfolio context. The pre-development team sees not just the chosen parcel but the alternatives it beat — useful when the chosen parcel hits an unexpected obstacle and a pivot becomes necessary.

How can investors evaluate parcels faster at portfolio scale?
By running the portfolio filter automatically rather than reviewing each feasibility PDF sequentially. The parcels that survive the filter are the ones worth the principal's attention.
How is this different from feasibility software?
Feasibility software is single-parcel. The platform adds the portfolio layer — ranked comparison, shared assumption set, distribution view. Teams running ten or more feasibility studies a week get the largest benefit.
Can I export the portfolio view?
Yes. Portfolio-level export includes the ranked list, the distribution, and every parcel's individual feasibility PDF.
Does the platform support multi-user teams?
Yes. Every parcel is assigned to an analyst; overrides are logged with the analyst identity for later review.
How is the shared assumption set kept current?
The platform updates the market-tied assumptions (cost bands, cap rates) on the training-data cadence. Firm-specific assumptions (target return, contingency policy) are set by the account admin.
Can I run 'what if the cost band moves five percent' across the portfolio?
Yes. Assumption-set changes propagate; the portfolio view updates. This is the stress-test view a principal runs before board meetings.
Is this priced per user?
No. $69 one-time gets the full platform. No seat pricing, no per-parcel fees.
How does the platform handle a portfolio of parcels across different asset classes?
Asset classes get separate sub-portfolios; comparisons within a sub-portfolio are apples-to-apples, and cross-asset comparisons are surfaced with the caveat visible.
Can I export the portfolio view for a board meeting?
Yes. Portfolio exports as a branded PDF with the ranked list, the distribution, the stress-test view, and the assumption-set version — the artifact boards actually read.
What happens when a parcel exits the pipeline (LOI signed or rejected)?
Rejected parcels move to the archive with the rejection reason. LOI-signed parcels progress into pre-development; the feasibility record follows them and remains queryable.

How does the platform handle capital calls across a portfolio?
Capital-call timing is a scenario input; the platform surfaces the aggregate call schedule across the portfolio so the principal sees the funding requirement over time.
Can the platform model an LP-fund structure?
LP-fund structures are supported at the portfolio level. Committed capital, uncalled capital, and vintage-year segmentation are inputs; distributions and IRR are tracked over the fund life.
