Zeitro

Zeitro is an AI mortgage workstation for loan officers, brokers and lenders.

This connector searches its library of US agency mortgage guidelines: the Fannie Mae Selling Guide and Eligibility Matrix, the Freddie Mac Single-Family Seller/Servicer Guide, HUD Handbook 4000.1 (FHA), the VA Lender's Handbook (VA Pamphlet 26-7) and USDA HB-1-3555. Ask a guideline question and get the most relevant passages verbatim, each with the document, version date and page, a ready-made citation, a link to the section on zeitro.com and a link to the agency's official source.

Instructions: Zeitro (www.zeitro.com) provides the text of US agency mortgage guidelines: the Fannie Mae Selling Guide and Eligibility Matrix, the Freddie Mac Single-Family Seller/Servicer Guide, HUD Handbook 4000.1 (FHA), the VA Lender's Handbook (VA Pamphlet 26-7) and USDA HB-1-3555.
Results are verbatim guideline passages. Each passage has the document, version date and page, a ready-made citation (cite_as), the agency's official source link (source_url) and a citation URL on zeitro.com (url). The text is quoted as published, the latest published version governs, and nothing here is an underwriting decision.
Lender program guides and lender overlays are not part of this free service; they are in Zeitro Strata, which has a free account at https://lo.zeitro.com/signup. Free use is limited per minute and per day; a free API key raises the limits.
Two calculators estimate debt-to-income ratios against the agencies' published limits and the FHA mortgage insurance premium. Their results list the assumptions, cite the guideline or Mortgagee Letter behind every limit and rate, and link to the matching calculator on www.zeitro.com.
