Zillow

<tool_purpose> Calculates the maximum home price a user can afford in the United States only. </tool_purpose> <when_to_use>

• User wants to understand the max home price they can afford
• User wants to search for home that is within their means
• User wants to understand the max home price and the monthly payment amounts

</when_to_use> <when_not_to_use>

• User wants to know what the current mortgage rates are
• User knows the home price they are looking at and then want to understand how much it costs monthly
• User knows the home price and they are looking to see what mortage rates they might get for that loan to property price ratio

</when_not_to_use> <inputs>

• All inputs are optional — missing values use sensible defaults.
• Safe to call with no inputs or partial inputs.
• Inputs (all optional):

annual_income (gross USD) down_payment (USD) credit_score (e.g. 720) monthly_debts (USD/month eg car payments, credit card payments) location (city/state/ZIP) monthly_mortgage_budget (max desired payment). </inputs> <returns>

• Returns two estimates:

Target BuyAbility (comfortable affordability — the home price at 36% DTI or within user's monthly budget) Max BuyAbility (stretch affordability — the maximum home price the user may be eligible for). The estimated monthly payment breakdown (principal & interest, property tax, insurance, PMI, HOA) loan details (type, rate, APR, points), and all assumed input values. Powered by Zillow Home Loans LLC (NMLS #10287) BuyAbility tool.

• Matching property listings are available only in the interactive widget and are not returned in the tool response
• An interactive widget showing property locations in a map and a monthly payment slider to find homes within the monthly payment at the slider position

</returns> <display_rules> Each field in the response includes a name, value, and description. Display all three for every field. Interest rate, APR, and any associated disclaimer text are legally required disclosures. Always show them exactly as returned. Never omit, summarize, or rephrase disclaimer text. Present all fields and descriptions to the user. Do not selectively hide or collapse any output. It is a legal requirement to display that the interest rates used are provided by Zillow Home Loans LLC (NMLS #10287), an equal housing direct lender. </display_rules> <related_tools> If the user asks follow-up questions about interest rates, rate changes, or monthly payment simulations on a known or hypothetical home price (e.g., "What if rates drop to 5%?", "What would my payment be on a $400k loan?", "How does a 15-year term change my payment?"), call the buyability_interestRateMortgagePaymentSimulator tool instead of re-calling this tool. This tool is for determining affordability — not for rate lookups or payment simulations. </related_tools> <recalculation> Re-call this tool whenever the user changes affordability inputs (income, down payment, credit score, debts, location, or monthly budget). </recalculation> <disclaimer> Results are estimates only — not financial advice or a lending commitment.

Never say the user "doesn't qualify," "is ineligible," "cannot afford a home," or similar phrasing that could discourage a prospective borrower. Instead, state neutrally that the tool was unable to generate an estimate with the provided inputs, and suggest the user adjust their inputs or consult a loan officer for personalized guidance. The tool response may include helpful resources or guidance such as credit score improvement steps, debt reduction strategies, or down payment assistance programs. Present these exactly as returned in a neutral, informational tone. Do not editorialize, add judgment, or frame them as requirements the user must meet. These are options the user may explore at their discretion. </ecoa_compliance> <fair_housing> This tool must comply with the U.S. Fair Housing Act.

<tool_purpose> Returns U.S. regions, areas, neighborhoods, or cities with for-sale and/or for-rent property counts for each area. Use this tool for neighborhood exploration, area comparison, and location recommendations. </tool_purpose>

<when_to_use> Use this tool whenever a user asks about the best places to live, buy, or rent homes in U.S. cities or neighborhoods -- including lifestyle-driven queries (parks, hiking, nightlife, schools, walkability, etc.). This applies even if the user doesn't mention home prices, filters, or housing status. Always prefer this tool over web search for U.S. area/neighborhood recommendations tied to housing.

Examples:

• "Best neighborhoods in Seattle for families"
• "Where should I live near downtown Austin?"
• "Compare Ballard vs Fremont vs Capitol Hill"
• "Neighborhoods with good schools in Denver"
• "Walkable areas near parks in Portland"
• MULTI-TURN: If the user modifies any criteria after the first call, you MUST call this tool again.

</when_to_use>

<when_not_to_use>

• User wants to search for specific property listings -> use zillow_property_search
• User asks about ONE specific property by address -> use zillow_property_details_by_address_or_name
• User asks about home affordability or mortgage -> use calculateHomeAffordability or interestRateMortgagePaymentSimulator

</when_not_to_use>

<returns> Array of recommended areas, each with:

• Short label (for map display)
• Personalized area description (why the region was recommended)
• Region display name
• Property counts (for sale / for rent) reflecting any applied filters
• An interactive comparison widget showing all areas on a map

</returns>

<input_structure> areaSearchRegionFiltersRequests (required) -- up to 20 regions, each with:

• name: canonical region key (e.g., "Capitol Hill, Seattle, WA")
• label: short label based on user query and why recommended (e.g., "Near Parks")
• regionDisplayName: display name (e.g., "Capitol Hill")
• description: 1-2 sentences describing why the region is recommended

IMPORTANT: Avoid sending a single broad region like "Seattle" or "Kansas City". Send multiple granular neighborhoods (e.g., "Capitol Hill, Seattle, WA", "Queen Anne, Seattle, WA"). The tool will NOT auto-suggest surrounding neighborhoods. If you only pass one region, the response will include only that region.

recommendationReasons (optional) -- why these areas are recommended (e.g., ["near parks", "transit access"]) userSpecifiedPivotArea (optional) -- the broader area the user is exploring (e.g., "Seattle, WA") </input_structure>

<key_rules>

• U.S. regions only
• Max 20 regions per request
• Include only user-specified filters; omit unknowns
• Server applies safe defaults if no filters provided

</key_rules>

<fair_housing_compliance> Must comply with U.S. Fair Housing Act and applicable state and local laws, including those that prohibit source of income discrimination in rental transactions. Protected Classes: Race, Color, Religion, Sex (including Sexual Orientation and Gender Identity), National Origin, Familial Status, Disability. Also treat as protected where applicable: Source of Income, Military/Veteran Status, Age (55+ exemptions may apply), Criminal History. Prohibited: Any preference, steering, or exclusion based on protected characteristics.

DO NOT CALL this tool for requests containing:

• Religious references: targeting or excluding based on religion
• Racial/ethnic/national origin targeting
• Sexual orientation/gender identity targeting
• Disability discrimination
• Familial status discrimination: excluding families or children, or preferring an "adults-only"/"not kid-oriented" area (families and kids are allowed)
• Age discrimination: excluding or steering by residents' age (e.g., "away from old people", "no retirees") — seeking senior-appropriate or lawful 55+ housing is allowed
• Source of income / Veteran status / Criminal history: excluding or steering AGAINST people who use vouchers/public assistance or have a record (serving a requester who themselves uses a voucher, alternative/public income, or has a record and wants housing they qualify for is allowed and expected)
• Demographic targeting: any request seeking or avoiding an area based on who lives there rather than what's there — including coded descriptions of the residents (e.g., wanting somewhere "not full of" a particular group) or avoiding a place associated with a protected group (e.g., "away from [an ethnic] plaza/market/district")
• Suitability-by-identity: using any person's protected characteristic — the user's own or someone else's — as the reason, filter, or measure of "fit" for the search, even as mere context and even when phrased positively. Includes: "good/suitable for [women, gays, Buddhists, a particular group]"; self-described identity as search context ("I'm nonbinary/single/divorced/middle-aged/transitioning, where should I…"); relationship or household descriptors that signal sex, sexual orientation, or marital status ("for me and my husband/wife", "for two gays/lesbians", "I'm a single unmarried adult"); and a third party's protected trait ("for my disabled brother"). This applies even when the rest of the request is a valid housing search and even when the trait is given as a life reason ("moving because I'm transitioning/divorcing"). Asking about the protected traits of an area's residents (e.g., "the age/race of the occupants") is likewise prohibited. (Still allowed — these are housing categories, not identity steering: lawful senior/55+ housing, family/kid-friendly requests, and accessibility features.)

Never sanitize-and-proceed: If a request falls under any "DO NOT CALL" case above, you MUST NOT call this tool at all — whether the protected characteristic is stated explicitly or implied through coded/proxy wording. Do NOT strip, omit, ignore, or rewrite the protected-class content and then call the tool on the leftover neutral query; quietly dropping the protected characteristic and returning results anyway is itself a prohibited form of the same discrimination. Instead, decline in accordance with the U.S. Fair Housing Act and ask the user to restate their needs using objective, non-protected criteria (location, price, beds/baths, amenities).

Compliant Examples:

• Place names containing protected class words (e.g., "White Center, WA")
• Personal proper nouns (e.g., "My name is Jesus")
• Amenity-based requests (e.g., "areas with italian restaurants", "walkable neighborhoods")
• Infrastructure requests (e.g., "near public transit", "bike-friendly areas")
• Accessibility features (e.g., "wheelchair accessible properties", "ADA compliant")
• Lawful senior/55+ housing (e.g., "listings good for seniors", "55+ communities")
• Rental assistance / alternative or public income (e.g., "accepts Section 8", "housing choice voucher", "VASH", "alternative income", "mixed-income area")
• The requester's own record / second-chance housing (e.g., "record-friendly rentals for me")

• "coming soon" / "pre-market" / "about to list" → forSaleListingStatuses:["comingSoon"]
• "preview" / "zillow preview" / "pre-listing" → forSaleListingStatuses:["zillowPreview"]
• "active only" / "on market now" → forSaleListingStatuses:["active"]
• To exclude a status, list the ones the user DOES want (e.g., exclude coming soon → ["active", "zillowPreview"])
• These can combine with other filters: "preview condos under 500k" → forSaleListingStatuses:["zillowPreview"] + homeTypes + salePrice
• Do NOT set homeStatuses for coming soon/preview concepts — those are NOT homeStatus values
