7 Risks of Buying a Colorado Home Without Proper Checks

Buying a Colorado home without the seven checks below puts $8,000 to $50,000 of repairs on the buyer after closing, and every one of those checks costs under $800 before closing. The Colorado Contract to Buy and Sell Real Estate gives the buyer dated deadlines to run each check and walk away with the earnest money if the result is bad. Miss a deadline and the check still happens, but the buyer pays for what it finds.

The seven risks below show up on Front Range homes month after month: an unread title exception, a foundation on expansive clay, a clay sewer line, radon above the action level, a hail-hit roof no insurer will bind, a Federal Pacific panel, and an unpermitted basement. Each section names the check, its Denver metro cost and the contract deadline that protects the buyer. The Colorado Home Buyer's Guide covers the full purchase timeline these checks sit inside.

How the Colorado contract deadlines protect a buyer

The Colorado contract lists the buyer's deadlines by date. The ones that matter for these checks:

• Title objection deadline. The buyer reads the title commitment and objects in writing to any exception or lien.
• Association documents deadline. Read the HOA or metro district documents; terminate if they do not fit.
• Inspection objection deadline. Inspect, test and deliver a written objection or termination; 7 to 10 days after contract is the Denver metro norm.
• Inspection resolution deadline. Seller and buyer agree on repairs or credits in writing, or the contract ends.
• Property insurance objection deadline. Get a policy quote on the actual house; terminate if no insurer will bind it at an acceptable price.

Terminate in writing before the matching deadline and the earnest money comes back; terminate after it and the earnest money, 1% to 2% of the price on most Denver metro contracts, is forfeited. The post on the buyer's due diligence checklist for Denver walks the deadlines in date order.

Risk 1: A title exception, a lien or a severed mineral estate

In Colorado the title company issues a title commitment within days of contract, and the seller pays for the owner's policy by custom. The commitment's Schedule B lists what the policy will not cover: easements, HOA covenants, an unreleased deed of trust from a refinance, a mechanic's lien or a judgment against the seller. A title search is what produces that list; reading it is the buyer's job before the title objection deadline.

Two Colorado items get missed. First, mineral rights: across Weld, Adams, Arapahoe and parts of Douglas county the oil, gas and mineral estate was severed from the surface decades ago, and the Colorado contract requires the seller to disclose whether the mineral estate has been transferred. Second, Colorado HOAs hold a lien with priority over the buyer's lender for six months of unpaid dues, so an unpaid balance on the seller's account follows the house. Get a payoff for every lien and an HOA status letter before the deadline.

Lot lines are a title question too. Colorado lenders accept an Improvement Location Certificate, $250 to $500, which shows the house and fences relative to the recorded lot; it is not a survey. A boundary survey, $1,000 to $3,000, is the only document that settles a fence dispute. The post on ILC vs. land survey for Colorado buyers explains which one to order.

Risk 2: A foundation on expansive bentonite clay

Much of the Denver metro, from Aurora and Parker through Castle Rock, Highlands Ranch, Lakewood and Broomfield, sits on bentonite clay that swells when wet and shrinks when dry. The soil lifts basement slabs, cracks foundation walls and pushes floors out of level. Colorado law requires the builder of a new home to give the buyer a soils report and a summary of expansive-soil hazards before closing; on a resale, ask the seller for that report first.

A home inspection notes cracks; it does not diagnose them. A horizontal crack, a stair-step crack in block, a slab lifted more than half an inch, or a floating basement wall with its gap closed means the buyer orders a structural engineer: $400 to $800 for a site visit and letter in the Denver metro, $1,000 to $2,500 for a full report with elevation survey. The repairs the letter names run from $3,000 for grading and drainage to $15,000 to $50,000 for helical piers. A foundation with active movement also fails an FHA or VA appraisal until repaired.

Risk 3: A clay or Orangeburg sewer line

Denver, Englewood, Littleton, Arvada, Lakewood and Aurora homes built before 1970 sit on clay tile sewer lines, and some 1950s and 1960s homes carry Orangeburg, a tar-paper pipe that collapses; tree roots enter at every joint. A sewer scope, a camera run from the cleanout to the city main, costs $150 to $300 and is the most common source of an inspection objection on the Front Range.

A spot repair in the yard runs $3,000 to $6,000. A full replacement to the main with a street cut and a city permit runs $8,000 to $25,000 in Denver. A buyer who skips the scope owns that bill the first time the basement drain backs up.

Risk 4: Radon above the action level

Every Front Range county sits in the EPA's highest radon zone, and the Colorado Department of Public Health and Environment reports that about half of Colorado homes tested come in above the EPA action level of 4 picocuries per liter. A 48-hour continuous monitor test costs $150 to $250 added to the inspection, placed on the inspector's first visit so the result lands before the deadline.

Colorado law requires the seller to disclose known test results and any mitigation system. A home with a system in place still gets tested, because fans fail. Mitigation on a home without a system costs $1,200 to $2,500 in the Denver metro, and sellers on the Front Range agree to that credit in most inspection resolutions. The post on radon and the Denver home purchase covers the testing week in detail.

Risk 5: A hail-hit roof no insurer will bind

Colorado hail season runs May to September, and a roof that looks fine from the driveway carries bruised shingles and dented vents that an insurer finds on the first claim. The inspector walks the roof or flies a drone and reports material, age and hail history; the buyer then gets a roofer's written estimate and an insurance quote on the actual address before the deadlines.

The insurance quote is the check buyers skip. Insurers along the Front Range decline or surcharge roofs older than 15 to 20 years, and a buyer who learns that after the property insurance objection deadline closes on a house with a $12,000 to $25,000 replacement bill. A Class 4 impact-resistant roof cuts the premium. The post on the roof report every Colorado buyer should read before closing lists what the inspector writes up.

Risk 6: A Federal Pacific or Zinsco electrical panel

Federal Pacific Stab-Lok and Zinsco panels sit in Denver metro homes built from the 1950s through the early 1980s. Breakers in these panels fail to trip under load, and inspectors flag them on sight. Most Colorado insurers require replacement before binding a policy. Replacement with a 200-amp panel by a licensed electrician costs $2,500 to $4,500, and Xcel Energy schedules the meter pull.

The inspector also checks for aluminum branch wiring in 1965 to 1973 homes, ungrounded outlets and a 100-amp service on a house now running central air and a car charger.

Risk 7: Unpermitted work, zoning limits and HOA or metro district rules

A basement, garage conversion or deck built without a permit is common across Denver, Aurora and Lakewood, and the buyer inherits it: the city can require the work be opened, corrected or removed, and the appraiser gives no value to unpermitted square footage. Pull the permit history from the city or county before the inspection objection deadline; Denver's records are online by address.

A buyer planning an accessory dwelling unit, a short-term rental or a home business checks the local zoning laws for the lot, and in Denver that means the zone district on the city map plus the ADU and short-term rental rules that go with it. The Denver ADU, zoning and historic district guide explains how to read the zone code.

HOA and metro district documents arrive by the association documents deadline. Read the reserve study, two years of minutes and any pending special assessment; a Denver condo building with a $2,000,000 roof project on the agenda means a $10,000 to $40,000 assessment per unit. A metro district adds mills to the property tax bill in most suburbs built after 1990 in Douglas, Adams, Arapahoe and Weld counties, and the metro district tax guide shows how to find the levy for a specific address.

The lender's checks and the repairs it requires

A mortgage adds the appraisal, and an FHA or VA appraiser also flags condition items: a roof with under two years of life, peeling paint on a pre-1978 home, a missing handrail, a failed well or septic test. The loan stops until the seller fixes them or the parties agree on a repair escrow. Mike Oswald, VP of Mortgage Lending at Rate, NMLS 261003, Equal Housing Lender, pre-underwrites Colorado buyers before they write offers so the appraisal is the only open item at the loan objection deadline. You are free to use any lender. The Colorado home financing guide and the Colorado mortgage pre-approval guide explain what a full pre-underwrite includes.

What the seven checks cost in the Denver metro

The whole set runs $1,500 to $3,000 on a Denver metro home, spent inside the inspection window with the earnest money still protected. The Colorado closing costs guide shows where these fees sit at closing, and the first-time buyer guide for Colorado covers budgeting for them before the offer.

The area pages carry the local version of these risks: sewer lines and permits in Denver, expansive soils and metro districts in Castle Rock and Parker, and hail and roof age across Aurora.
