Overview

AI-generated overview

Lets an assistant look up HUD Fair Market Rents and run the site's rental-property calculators, from cap rate and DSCR to lease renewal and 1031 illustrations.

What you can do
A read-only set of 16 tools built on the site's stored data files. It looks up HUD FY2027 Fair Market Rent or Small Area FMR by ZIP and bedroom count, estimates rent, and returns covered-market rows with sample medians. Calculators cover cap rate, cash flow, DSCR, amortization, operating expenses, gross yield, rent-to-income, STR versus long-term comparison, lease renewal advice, and planning illustrations for 1031 exchanges and cost segregation. A digest of city landlord-tenant rules is also available.
When to use it
Useful when evaluating a rental property: checking voucher rent benchmarks for a ZIP, running quick underwriting math, comparing short-term and long-term scenarios, or drafting a renewal recommendation. Also handy for rough planning illustrations of tax treatments.
Requirements
Runs as a remote streamable HTTP endpoint at the provider's site; no package, environment variables, headers or authentication are declared. Network access to that endpoint is needed.
Before you install
Many outputs are labeled estimates or illustrations, not measurements: benchmark bands, turnover costs, closing costs and tax figures are illustrative, and the tax and legal tools explicitly say they are not tax or legal advice. Some lookups return errors for counties or cities not in the stored files. Treat results as planning inputs, not authoritative figures.

Installation

In SourceWeft

  1. Open RentalAnalytics rent tools 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/com.rentalanalytics%2Frent-tools/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

HUD Fair Market Rent by ZIP

Published FY2027 HUD Fair Market Rent or Small Area FMR for a ZIP and bedroom count (studio through 4). This is the 40th-percentile voucher rent stored in the site's Section 8 extract, not a market-rent estimate. If the ZIP is absent, or the extract has more than one town rent, the tool says so and does not pick a number.

Parametersziprequiredbedroomsrequired

estimate_rent

Statistical median rent

The rent estimator on /tools/rent-estimator. Hero is the HUD FY2027 50th-percentile area rent scaled onto the ZIP FMR or SAFMR when that area is in hud-50th-sample.json, then aged with the BLS CPI Shelter rate in the script and a property-type multiplier. FMR stays the labeled 40th-percentile voucher figure. ACS B25031 is a second anchor when the sample has that ZIP. A ZIP missing from both the sample and the Section 8 extract returns an error. No national rent is invented for a missing ZIP.

Parametersziprequiredbedroomsproperty_type

calculate_cap_rate

Cap rate

Cap rate calculator: NOI divided by purchase price, compared with the band stored in cap-rate-benchmarks.json for the ZIP's metro tier. Unknown ZIPs use the file's Tier 2 band, which is what the page does. Cash-on-cash, when financed, uses the page's 3% closing estimate. Bands are the file's estimated survey ranges, not a new comp.

Parameterszipfinancedvacancy_pctrequiredinterest_pctloan_term_yrsproperty_typerequiredpurchase_pricerequireddown_payment_pctannual_gross_rentrequiredop_expenses_annualrequired

calculate_cash_flow

Cash flow

Cash flow analyzer. Itemized P&L, cap rate, gross yield, cash-on-cash, and break-even occupancy from the inputs you pass. Closing costs in the cash-on-cash line are the page's 3% estimate. Taxes and insurance are annual; maintenance is monthly.

ParametersrentrequiredtermdpPcttaxesintPctmgmtPctvacancypurchaserequiredinsurancemaintenance

calculate_dscr

DSCR

DSCR calculator. NOI is rent times 12 times (1 minus vacancy) minus taxes, insurance, HOA, and other annual costs. Debt service is the fully amortizing payment times 12. DSCR is NOI divided by debt service. Max loan is the principal whose payment equals NOI divided by the target DSCR you pass. 1.25 is not assumed.

ParametersratePctrequiredhoaAnnualtermYearsrequiredloanAmountrequiredtargetDscrvacancyPctmonthlyRentrequiredotherAnnualtaxesAnnualinsuranceAnnual

calculate_amortization

Amortization

Fully amortizing mortgage schedule from the amortization calculator. Interest is rounded to the cent each month. Pass include_schedule true to get every row. Otherwise the tool returns the payment, payoff date, total interest, and total paid.

ParametersyearsrequiredprincipalrequiredextraMonthlyannualRatePctrequiredfirstPaymentDateinclude_schedule

compare_str_ltr

Short-term vs long-term rent

STR vs long-term comparison. Short-term revenue is nightly rate times occupied nights. Long-term rent is the monthly rent you pass, or, if you omit it, the ACS B25031 cell for that ZIP and bedroom when the sample has one, otherwise the HUD FMR for bedrooms 0 through 4. If neither source has a rent, pass monthly_rent. The tool does not invent one.

advise_lease_renewal

Lease renewal

Lease renewal advisor. Market rent is estimate_rent for the ZIP. The recommended rent follows the page's gap bands: hold inside 5%, blend 65% of the gap when under market, blend 50% when over market. Turnover cost is the page's illustrative 1 to 2 months of current rent, not a measured local figure. If the rent estimate has no median, this tool stops.

Parametersziprequiredbedroomscurrent_rentrequiredproperty_type

lookup_covered_market

Covered-market snapshot

City rows stored in markets.json (the 15-city sample behind the rent-growth tracker and vacancy panel), plus the sample median and mean those pages compute. YoY, vacancy, and cap rate on each row are the file's labeled estimates. The 12-month illustration multiplies the stored 2-bedroom FMR by the script's CPI Shelter rate. It is not a metro forecast. An unknown city returns an error.

Parameterscityslugstate

calculate_opex

Operating expense benchmark

Operating-expense lines as a percent of effective gross income, compared with the illustrative national bands in opex-benchmarks.json. Those bands are labeled illustrative in the file. They are not a metro measurement.

lookup_rent_to_income

Rent-to-income

Census median rent, renter income, and HUD income limits stored for a state or county in rent-to-income.json. The ratio is the file's stored hundredths, which uses the site's half-up formula. A county that is not in the file returns an error.

Parametersstaterequiredcounty

lookup_gross_yield

Stored gross yield

Gross rent yield stored for a state or county in gross-yield.json. The yield is the file's stored figure. A county that is not in the file returns an error.

Parametersstaterequiredcounty

calculate_gross_yield

Gross yield from rent and value

Gross yield for a monthly rent and value you pass, using the site's half-up hundredths formula: floor((rent * 12 * 10000 + floor(value / 2)) / value). It does not look up a price.

Parametersvaluerequiredmonthly_rentrequired

illustrate_1031_exchange

1031 exchange illustration

Partial Form 8824 illustration from the 1031 calculator (lines 15, 16, 18, 19, 20, and 24 when line 23 equals line 20). Line 21 recapture is not computed. This is a planning illustration, not a filed return and not tax advice.

illustrate_cost_segregation

Cost segregation year 1

Year-1 cost segregation worksheet. Land percent and cost-segregation percent are required because the form has no default for them. Bonus percent comes from tax-params.json when you pass acquired_date and placed_year. Otherwise it uses the form field's stored default. Estimates for planning; not tax advice.

lookup_city_rules

City landlord-tenant digest

Plain-English landlord-tenant digest stored in regulations.json for the cities that file covers. If the city is not in the file, the tool says so. Estimates for planning; not legal advice.
