Overview

Remote commercial real estate capital stack calculator that lets an assistant model senior, mezzanine, preferred and common equity layers with costs, coverage…

What you can do
  • Build a capital stack on a deal: senior loan, mezzanine, preferred equity and leftover common equity, with an optional one-tier JV split, returning layer amounts, shares of cost, attachment/detachment LTV and LTC, blended cost of capital, coverage, debt yields and LP/sponsor IRRs
  • Look up current capital costs: Altus Group Q2 2026 average lender quotes by LTV band, the 10-year Treasury and implied all-in senior and mezzanine rates, plus what public mortgage REITs report earning
  • List capital providers by layer: Fannie Mae DUS and Freddie Mac Optigo agency lenders and public mortgage REITs holding mezzanine or preferred equity, filterable by list or partial name
When to use it
Useful when sizing or comparing a commercial real estate debt and equity structure, checking blended cost and coverage, or finding which agency lenders and mortgage REITs operate in a given layer. It suits early-stage underwriting arithmetic rather than a quote or appraisal.
Requirements
A remote streamable HTTP endpoint at cre.capital; no package, environment variable or header is declared, and no authentication is declared. Network access to the endpoint is needed.
Before you install
Results are arithmetic on the inputs, not a quote, appraisal, projection, offer of securities or investment advice, and the publisher takes senior and mezzanine debt requests through its site. Cost inputs rest on a specific survey quarter and Treasury curve, so figures age; cite the source links returned with each result.

Installation

In SourceWeft

  1. Open CRE Capital: capital stack calculator in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/capital.cre%2Fcre-capital/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Build a CRE capital stack

Runs the cre.capital stack builder on a deal: senior loan, mezzanine, preferred equity and the common equity left over, with an optional one-tier JV split. Returns each layer's amount, share of cost and attachment/detachment LTV and LTC, blended cost of capital, cost of debt and preferred, common equity IRR and multiple, unlevered IRR, senior and all-debt DSCR, coverage including pref current pay, debt yields, LP and sponsor IRRs, the exit and the yearly cash flows. Rates you leave out start from the current 10-year Treasury plus Altus Group Q2 2026 average quotes. Arithmetic on your inputs, not a quote or a projection.

What each capital stack layer costs

What senior debt, mezzanine and preferred equity cost: Altus Group's Q2 2026 average lender quotes (fixed and floating, by LTV band, as spreads over the 5-year or 10-year Treasury or Term SOFR), the current 10-year Treasury with the implied all-in senior and mezzanine rates, and what public mortgage REITs report earning on each layer in their 10-Qs for the quarter ended June 30, 2026. Filter by layer.

Parameterslayer

list_capital_providers

Who provides each capital stack layer

Names of firms in the business of each layer, only as the institutions publish them: Fannie Mae DUS lenders and Freddie Mac Optigo lenders (senior agency multifamily debt) and public mortgage REITs that hold mezzanine loans or preferred equity per their 10-Qs. Filter by list or by part of a name. Being on a list does not mean a firm will quote a given deal.
