The HUD MAP Guide, chapter by chapter.

The short answer

The HUD MAP Guide is the Multifamily Accelerated Processing Guide, HUD's handbook 4430.G for FHA multifamily mortgage insurance. It sets national standards for how approved MAP lenders prepare, underwrite and submit applications, and how those loans are built, cost-certified and closed. It covers Sections 220, 221(d)(4), 223(a)(7), 223(f), 231 and 241(a). Section 232 healthcare loans follow a separate handbook.

The current edition is the 2020 MAP Guide (REV-3), issued December 18, 2020, effective March 18, 2021, with the published text dated March 19, 2021. HUD amends it through mortgagee letters rather than reissuing it. The 2025 ratio changes, the 2026 environmental changes and the annual threshold updates all sit outside the PDF, so a lender working from the Guide alone is working from an incomplete rulebook.

What does the MAP Guide govern?

The Guide says it provides, in one volume with appendices, guidance for HUD staff, lenders, third-party consultants, borrowers and other industry participants. It covers program descriptions, borrower and lender eligibility, application requirements, underwriting standards for every technical discipline, construction loan administration and, since 2020, closing.

It also sets its own rank. Where the Guide conflicts with older HUD handbooks or form instructions for a MAP application, the Guide takes precedence. A Multifamily Regional Director may waive non-regulatory provisions, regulatory provisions need the FHA Commissioner, and statutory provisions cannot be waived. Waivers are documented on form HUD-2 in the Regional Center docket.

One small rule trips new staff: periods longer than two weeks are counted in calendar days, and periods of two weeks or less in business days. Every deadline in the closing calendar depends on reading that correctly.

Which edition of the MAP Guide is current?

The 2020 MAP Guide is the edition in force. HUD's revision history runs 2002, August 2011, January 2016 and December 2020. The 2020 revision moved to a decimal numbering system (chapter, section, subsection) and folded the closing procedures that had sat in a separate Closing Guide since 2011 back in as Chapter 19.

HUD has posted a Draft MAP Guide 2024 on its Multifamily Housing Policy Drafting Table, with chapters released for feedback on a rolling basis. A draft is not policy. Until HUD publishes a final revision with a transmittal, applications are underwritten to the 2020 Guide as amended by mortgagee letters, and HUD's own 2026 letters still cite the 2020 Guide section numbers.

Which mortgagee letters amend the MAP Guide?

The letters below change numbers a MAP underwriter or closer uses every week. Each one says the Guide will be revised to match, but the PDF has not been reissued, so the letter is the operative text.

What does each chapter of the MAP Guide cover?

The Guide has 19 chapters and a set of numbered appendices that hold the checklists, exhibit lists and forms. The table maps each chapter to the people on a MAP lender's team who live in it. Titles are HUD's; the user column reflects how lending teams typically divide the work.

What is in the MAP Guide appendices?

The appendices hold the working material. Appendix 2 covers quality control plans and identity of interest, Appendix 3 program specifications and limitations, Appendix 4 the application processing documents and exhibit checklists, Appendix 5 architectural and construction analysis including the capital needs assessment, Appendix 7 valuation processing, Appendix 8 mortgage credit requirements, Appendix 9 environmental analysis, Appendices 12 and 13 construction and cost certification, and Appendix 15 the lender deficiency categories HUD uses in oversight.

For a processor, Appendix 4 is where the exhibit list for a firm commitment application lives. For a closer, Chapter 19 and the closing document forms carry the load, which is why most lenders build their HUD loan closing checklist from those two sources instead of from memory.

How should a new MAP team member read the Guide?

Not front to back. The Guide runs to hundreds of pages, and the people who use it best read it by role and keep the amending letters next to the chapter they change.

• 1
  Start with Chapter 1

  It explains which programs MAP covers, how waivers work and how the Guide ranks against other HUD guidance.
• 2
  Read Chapter 3 with ML 2025-03 and ML 2026-01 open

  The sizing ratios printed in the Guide are no longer current for most deals.
• 3
  Read your role's chapter and its appendix

  Underwriters pair Chapter 8 with Appendix 8; construction staff pair Chapters 12 and 13 with Appendices 12 and 13.
• 4
  Closers read Chapter 19 end to end

  It sets the roles of lender's counsel, the HUD closing attorney and the Regional Center, and the package deadlines.
• 5
  Check the mortgagee letter index monthly

  HUD lists every new letter on its index page; multifamily letters often change Guide sections without a reissue.

How does the MAP Guide shape a closing calendar?

Chapter 19 drives the back half of every deal: the tentative closing date, the draft package from lender's counsel, HUD's preliminary review and the confirmed date. The paperwork volume and the closing sequence are covered in why HUD loans take so much paperwork, so they are not repeated here.

What the Guide cannot do is keep the team on its dates. Closers who estimate the calendar backward from the target closing, with a closing timeline estimator or a simple countback, set internal deadlines that land the package early. The common failure is running a HUD closing through shared folders and email threads, where nobody sees which exhibit is late; the Prodeal vs SharePoint and email comparison walks through that gap.

How do MAP lenders keep the Guide usable day to day?

Strong HUD lending teams keep one internal crosswalk: each checklist line tied to the Guide section or mortgagee letter that requires it. When HUD issues a letter, the team updates the crosswalk once and every new deal inherits the change.

The same discipline helps at the end. A closing binder organized by HUD exhibit, with the Guide section noted, lets asset management and auditors find what HUD approved and why. A shared checklist with owners, due dates, document status and an audit trail is the practical version of that crosswalk.
