5 things to check before you buy a flipped house

Before buying a flipped house, run five public-record checks: seller hold time, permits, county square footage vs. the listing, whether past "sold" prices were real sales, and the seller disclosure. Each takes minutes, and we flip houses ourselves.

1. How long has the seller held it, and for how much?County deed records

Bought recorded deed, price Listed months later, asking price hold time: shorter = look harder Renovation actually spent Seller markup Purchase price Asking price

Illustrative. Price gap minus seller markup = what was really spent on the house.

How

Open the county assessor or recorder page (Pierce County, WA: ATIP parcel search). The last deed shows the date and, in most states, the price paid.

Red flag

A few months' hold and a big markup leave little room for real work. Inspect as if nothing behind the walls was touched.

2. Was the work permitted?County or city permit portal

Illustrative. Electrical, plumbing, roofing, and structural work normally require permits.

How

Search the address on the permit portal (Tacoma: Accela permit portal) and compare against the listing's claims.

Red flag

Zero permits under a listing that promises new systems. It resurfaces in insurance claims, appraisals, and your resale.

3. Does the square footage match the county?County record vs. MLS

MLS listing 3,367 sqft County record 2,483 finished 884 unfinished Price per finished sqft $120 on MLS area $163 on county area +36%

From our public sample report: the 884 sqft gap was an unfinished basement counted as living area.

How

Compare the listing total against the county's finished above-grade area. Flipped listings lean on "big and new."

Red flag

A gap of hundreds of square feet. Every per-sqft number, including your comps, is off by the same ratio.

4. Is every "sold" price a real sale?Deed chain

Portal says County deed says "Sold" Arm's-lengthvalid comp "Sold" Foreclosurenot a market price "Sold" Partial interestshare of title only "Sold" Family transfernot a market price

Portals label most recorded transfers "Sold." Only an arm's-length sale shows what the market paid.

How

Open the recorded deed behind each portal "sale." Document type and parties tell you if it was real.

Red flag

A "bargain" measured against a foreclosure or partial-interest transfer. That reference was never a market price.

5. Ask for the seller disclosureWashington: Form 17

Washington: a buyer's waiver does not cover the environmental section when the seller knows of environmental issues.

Most states require a written seller disclosure; names and exemptions vary. Washington's is Form 17 (RCW 64.06.010).

How

Request it before you write an offer. Read the "yes" answers and the blanks.

Red flag

No disclosure because the seller is exempt. The inspection now carries twice the weight.

Where flippers save money

Sewer scope
Camera down the main line. Roots and breaks never show in photos.
Roof
Age, layers, flashing. "New roof" needs a permit or invoice behind it.
Electrical panel
Brand, capacity, and whether "new wiring" reaches past the first outlet.

Floors and paint are easy to make pretty. Point your inspector at what is hidden.

Why a flipper would publish this. A well-done flip survives every check above; a seller who resists them is your answer. Our methodology runs the same checks on every deal we underwrite.

FAQ

Where do I find county records for a house?

Search for your county name plus assessor or property search. Most US counties publish a free parcel lookup with ownership history, recorded deeds, assessed value, and building details. Permit history is usually on a separate county or city permit portal.

Is unpermitted work always a deal-breaker?

No, but it changes the price. Unpermitted electrical, plumbing, or structural work can complicate insurance claims, appraisals, and your own resale. Treat it as a reason to inspect harder and to budget for correction, not as a reason to skip the inspection.

Why does the county square footage differ from the listing?

Listings often add unfinished basements, garages, or converted spaces to the total. County records typically separate finished above-grade area from unfinished space. Price per square foot only means something when both sides use the same definition.

Does PropDossier inspect the property?

No. A PropDossier report organizes public records and listing data and links every figure to its source. It is not an inspection, an appraisal, or investment advice. Hire a licensed inspector before you buy.
