29 sources shown
Census new-home sales and inventory ↗
United States and Census regions · new single-family homes
Read contracts, new-home inventory and months of supply. Annualized sales rates are not monthly closings; subsequent canceled contracts are not removed from the reported sales series.
Free monthly release. National and regional evidence does not establish a community’s absorption rate.
Open source ↗BLS producer prices for construction materials ↗
U.S. producer price indexes · category-specific coverage
Understand material price trends and revisions. Index changes are not delivered supplier quotes, local labor rates or the total cost of building a home.
Free published indexes and methodology. Match the index category and observation period to the cost exposure being studied.
Open source ↗FHFA house-price indexes and methodology ↗
U.S. and available regional/local house-price indexes
Inspect broad repeat-transaction house-price trends and each series’ coverage. These indexes are not new-build sale comparables or a forecast for a specific subdivision.
Free public data. All-transactions indexes include refinancing appraisals as well as sale transactions.
Open source ↗NAHB acquisition, development and construction financing survey ↗
Survey of participating residential builders and developers
Review credit availability, loan categories, rates and initial points. Use this as financing context before obtaining project-specific terms; survey averages are not loan offers.
Public quarterly summary. Check the survey period and distinguish contract interest from the effective cost including points.
Open source ↗Census QuickFacts ↗
U.S. states, counties and cities of 5,000 or more
Compare population, household income and housing-stock context. Check each row’s date and geography; city medians are not qualified buyer demand or new-build sale comparables.
Free public tables. Different rows can use different survey periods and population vintages.
Open source ↗Census Building Permits Survey · readable guide →
U.S.; available state, metro, county and permit-issuing place tables
Review residential units authorized by building permits to understand an area’s proposed supply. Authorizations are not construction starts, completed homes or occupied units.

Open source · readable guide →Mecklenburg property records & taxes ↗
Mecklenburg County, North Carolina
Find the county’s property-value, record, revaluation and tax-bill tools for Charlotte-area parcels. Assessment records are not title insurance, a survey or an acquisition appraisal.
Free public research hub. Confirm the parcel’s county and distinguish assessed value from the tax bill.
Open source ↗Wake County real estate search ↗
Wake County, North Carolina
Search public parcel and real-estate records by address or parcel identifier, with links to tax bills and maps. Records can change and do not replace a title review or current survey.
Free public search. Check county jurisdiction for a Raleigh-area property.
Open source ↗Dallas Central Appraisal District ↗
Dallas County, Texas
Research appraisal records, parcel maps and taxing units. DCAD covers Dallas County and explicitly directs title research to the county clerk; appraisal values are not sale prices.
Free public appraisal search. Dallas-area properties outside Dallas County use another appraisal district.
Open source ↗Harris Central Appraisal District search ↗
Harris County, Texas
Look up public real-property appraisal records by address or account. The district does not determine quality of title; verify the county before researching a Houston-area parcel.
Free public search. A county appraisal is not a current market valuation or a statement of all transaction costs.
Open source ↗Maricopa parcel maps and records ↗
Maricopa County, Arizona · tool coverage varies
Open the county’s official hub for parcel mapping, assessor information, planning maps and permit records. County planning records cover unincorporated areas; confirm the authority for a Phoenix-area site.

Open source ↗Hillsborough property data tools ↗
Hillsborough County, Florida
Open property record cards, parcel maps and the property appraiser’s tax estimator. Records and estimates do not replace a title search, boundary survey or a confirmed post-purchase tax assessment.
Free public tools. Interactive mapping requires a compatible browser; follow source disclaimers.
Open source ↗Charlotte zoning & UDO administration ↗
City of Charlotte zoning jurisdiction
Find zoning-use guidance, verification letters, Unified Development Ordinance resources and review contacts. A map or general rule does not confirm that a specific project will be approved.
Free public guidance. Formal letters, reviews and permits may have fees and separate requirements.
Open source ↗Raleigh permits & development ↗
City of Raleigh permitting jurisdiction
Start with the city’s permit guidance and development portal resources. An application or permit record is not proof of completed construction, legal occupancy or remaining project costs.
Free public guidance. Permit applications may require registration and fees; city and county systems differ.
Open source ↗Dallas planning and zoning ↗
City of Dallas · current planning
Find the city’s zoning-change, planned-development, development-plan and related review guidance. This planning page is not evidence that a building permit has been issued for a parcel.
Free planning guidance. Verify the applicable zoning case, conditions and separate building-permit requirements.

Find the city’s permitting center, construction-code, inspection and fee-schedule resources. Do not treat a general permitting guide as confirmation of a site’s allowed use or deed restrictions.

City of Phoenix
Find zoning, site-plan review, building permits, codes and fee information, including current portal links. Requirements depend on the parcel, proposed use and project design.

Public map service linked by FEMA’s FloodSmart. Browser access may vary; inspect map dates and revisions.
Open source ↗FloodSmart flood-insurance education ↗
United States · National Flood Insurance Program
Learn how flood risk, coverage and the National Flood Insurance Program work. Educational material does not establish a property’s insurability, premium or exact coverage.

Open source ↗NOAA Sea Level Rise Viewer ↗
Mapped U.S. coastal areas; useful for coastal Houston and Tampa context
Explore coastal inundation scenarios and mapping confidence. NOAA describes this as a planning reference, not a parcel-specific flood prediction or permitting determination.
Free interactive viewer. Coverage varies; scenarios exclude some processes and require site-level follow-up.
Open source ↗NAIC property-insurance basics ↗
United States · state insurance regulator association
Understand homeowners coverage, deductibles and questions to bring to an insurer. General homeowners information does not confirm construction, builder’s-risk, vacancy or business coverage.
Free public education from the NAIC. Coverage and pricing require property-specific policy review.
Open source ↗Texas insurance consumer guides ↗
Texas
Find the state regulator’s residential and commercial property-insurance guides. Use the guide that fits the property’s actual use; general information is not a binding coverage decision.
Free state-regulator publications. Policy purchase and underwriting remain separate.

Open source ↗Charlotte Water capacity assurance ↗
Charlotte Water service area · qualifying wastewater connections

Official process guidance. Obtain and check the actual approval for your site, flow and schedule.
Open source ↗Raleigh review times and permit dashboards ↗
City of Raleigh · application types and published review periods
Separate intake, review cycles, applicant resubmissions and final review. Published benchmarks are goals, and the dashboards provide historical processing context rather than a promised permit date.
Free official dashboards and definitions. Check the application type, observation period and remaining project steps.
Open source ↗HUD Fair Market Rents ↗
HUD metro areas, area subdivisions and nonmetropolitan counties
Look up HUD rent benchmarks by bedroom count and fiscal year. FMRs are program benchmarks, not a guarantee of voucher payment, current asking rents or rents for a specific building.
Free public lookup and downloads. The separate API requires an access token; this directory uses no API.
Open source ↗HUD multifamily financing programs ↗
United States · eligible multifamily projects
Compare descriptions of FHA multifamily mortgage-insurance programs for development, rehabilitation and other uses. Program descriptions are not loan approval or a financing commitment.

U.S. federal tax treatment of residential rental activity
