Data & calculation methodology

Market data: a sample of listings

Market snapshots aggregate property records within each configured region’s geographic bounds. These regions are search areas and can differ from city limits. They describe DoorHunter’s captured listings, rather than every home, household, or transaction in a city.

Listing prices are asking prices for active for-sale listings. Asking rents come from a separate active rental cohort. A median is the middle usable value; records without a valid positive price or rent are excluded from that metric’s sample. Counts can therefore differ across metrics. These figures are not closed-sale prices or signed lease amounts.

Dates and coverage

A snapshot’s data date is the oldest completion time among the successful scrape jobs in its source cycle. The refresh time indicates when the aggregate was calculated or copied to the website; it does not make the source listings newer. Public market pages qualify for indexing only with price and rent samples, positive medians, and a valid source date no more than 30 days old. Older snapshots remain clearly labeled for reference.

A region’s next snapshot requires all configured enabled source targets to have completed a newer successful cycle. Missing or incomplete provider coverage can delay publication. Bedroom mix, condition, listing duplication across providers, and geographic coverage can affect the sample. Read the displayed sample sizes before comparing two regions.

Market ratios and estimated yields

Monthly rent-to-price ratio divides the median asking rent by the median listing price. Those medians describe different property cohorts. The ratio is a screening measure, not a property’s cash-on-cash return.

Estimated gross rental yield annualizes modeled property rent and divides by asking price, before expenses. Estimated cap rate uses the snapshot’s operating-expense assumptions. The current default baseline deducts 10% of rent for management, 5% for maintenance, 5% for vacancy, and annual taxes and insurance equal to 1.5% of asking price. It excludes financing and capital costs. It is a modeled market screening estimate. Use property-specific tax bills, insurance quotes, management fees, and maintenance budgets for underwriting.

Investment calculators

• Rental cash flow subtracts vacancy, operating expenses, replacement reserves, and debt service. Cash-on-cash return divides annual cash flow by initial cash invested.
• BRRRR separates acquisition carrying costs from post-refinance operations. Net refinance proceeds reduce the cash left invested.
• Fix and flip deducts purchase, renovation, financing, holding, and sale costs. Project return covers the full project and is not annualized.
• Short-term rental uses 365 nights a year and your occupancy, nightly rate, and average stay. The result is an annual average, not a monthly seasonal forecast.
• Rehab budgeting totals line-item quantities and unit costs. Verify scope and prices with local contractors.

Loan payments use the entered rate, term, and loan type. Estimates exclude income taxes and appreciation; include additional costs in the provided expense fields. Empty or invalid required inputs cannot produce a valid estimate. A zero or negative cash investment has no meaningful percentage-return denominator.

Verify an individual property

Confirm condition, permits, title, taxes, insurance, rents, comparable sales, and loan terms independently. A market median does not establish a specific property’s rental value or after-repair value. The app’s estimate is a starting point for research and can be unavailable when evidence is insufficient.
