They pull from credit header data, which is why they beat the free stuff.

The column headers represent different categories (e.g., Address, New Roof, New HVAC, Refrigerator, Oven/Range, Dishwasher, Water Heater, etc.).

Quote from @Marc Winter: After just finishing my home inspection recertification, I plugged your question into the system, heres what it said:Most likely cause: Differential movement + thermal expansionThis type of crack is commonly caused by one or more of:Thermal expansion/contraction of a long brick wall (brick expands more than people realize)Lack of control joints in the masonryMinor differential settlement between structural elements (floor line, lintel, or bond beam)Possible interaction with a floor diaphragm or window header lineHow I’d classify itCategory: Non-structural / serviceability crackSeverity: Low to moderateRisk: Usually cosmetic unless it continues to growWhat would confirm thisCrack aligns near a floor levelNo stepped “stair-step” patternNo widening at one endInterior walls at same level may show hairline cracksThe stepped / jagged, diagonal through mortar jointsWhat it looks likeStair-step pattern following mortar jointsChanges direction vertically and horizontallyLocalized area rather than full-lengthSome patched/effloresced areas nearby⚠️ Most likely cause: Foundation movement (settlement or heave)This pattern is classic for:Differential foundation settlementSoil shrink/swell (expansive clay, poor drainage)Localized footing movement (corner or bearing point)The stair-step pattern forms because masonry is weakest at mortar joints, so stress releases there.How I’d classify itCategory: Structural movement crackSeverity: Moderate (possibly increasing)Risk: Needs monitoring; may require repair beyond cosmeticWhat would raise concernCrack width > ~⅛ inchNoticeable brick displacement (one side proud)Interior drywall cracks aligning with this locationDoors/windows near this area sticking🧠 Why these two cracks have different causes (important)Even though they’re on the same wall:1. global wall movement (temperature / restraint)2.  

If the student has a lot of money and a very healthy balance sheet and banking contacts that is as importnant if not more so than knowing the difference between a header and a joist or in what order you build the house in :)

The style of every article is very AI: no real commentary or detail on things, lots of large bold headers with a couple sentences below each. 

Since the OP put California on the header of his post, Ill assume as such.

Also, I love chatgpt, but using it for your headers and posts and copy and pasting get less attention I have heard.

It's very simple, here is the header for one sheet:# Of RentalsAddressDate BoughtYear Roof was put onCost of PropertyValue of Property 2017Value of Property 2021TaxInsuranceMortgageMaint/HOAAC FiltersRent Per MonthThen I have another sheet to keep track of any expenses for the year:# Of RentalsAddressCityJanFebMarAprMayEverything is very organized on these two sheets for the CPA every January.

The cool part about redfin is that the table column headers are sortable and also include a dollars per square foot column.
