Common Mistakes Homeowners Make Before Selling

Selling a home involves dozens of decisions — many of them made under stress, time pressure, or based on incomplete information. It's easy to make mistakes. The good news is, most of the costly ones are predictable and avoidable if you know what to look for.

This guide walks through the most common errors Michigan homeowners make before and during the selling process — and how to sidestep them entirely.

Mistake #1: Overspending on the Wrong Repairs

This is the most common — and most expensive — mistake sellers make. Many homeowners assume they need to fix everything before selling, and they pour tens of thousands of dollars into renovations that return 50–70 cents on the dollar.

The fix: Before spending a dime on repairs, check the ROI. Fresh paint almost always pays for itself (100–150% ROI). A new roof typically returns 60–70%. A luxury kitchen remodel? Maybe 50%. If your goal is to maximize the net cash you walk away with, don't spend $30,000 to add $18,000 in value — you're better off selling as-is. Read our full guide: Should I Make Repairs or Sell As-Is?

Mistake #2: Not Getting a Cash Offer Before Listing

Many homeowners sign with a Realtor without ever exploring what a cash buyer would offer. A cash sale eliminates agent commissions (5–6%), repair costs, carrying costs, and months of uncertainty. Even if the headline cash offer is lower than the potential list price, your net proceeds might be very close — and you get the money in a week instead of months.

Mistake #3: Pricing Based on Emotion, Not Data

You've lived in your home for 15 years. You raised your kids there. You remodeled the kitchen in 2018. That all matters to you — but the market doesn't care. Overpricing leads to your home sitting unsold, which then triggers price cuts that make buyers wonder what's wrong with it.

The fix: Price based on comparable sales (comps) of similar homes in your area that have sold in the last 3–6 months — not what your neighbor listed for, not what Zillow says, and not what you "feel" it's worth. A good agent or cash buyer will walk you through the comps.

Mistake #4: Ignoring Carrying Costs

Every month your home sits unsold, you're paying the mortgage, property taxes, insurance, utilities, and maintenance. On a typical Michigan home, that's $1,000–$2,000 per month — and those costs come directly out of your eventual proceeds. A sale that takes six months costs you $6,000–$12,000 in carrying costs alone. When comparing a cash offer (closing in 7–14 days) against a traditional listing (closing in 45–90+ days), factor in those carrying costs. You might find the "lower" cash offer actually puts more money in your pocket. See our holding cost calculator.

Mistake #5: Skipping the Pre-Sale Numbers

Many sellers don't calculate what they'll actually net from the sale before committing to a path. They see a potential sale price of $200,000 and mentally spend it — then are shocked when the mortgage payoff, commissions, closing costs, and taxes leave them with $140,000.

The fix: Before you commit to selling, calculate your estimated net proceeds: sale price minus mortgage balance, minus commissions (if applicable), minus closing costs, minus any repairs you plan to make. Use our closing cost calculator. Know your number before you make decisions.

Mistake #6: Not Disclosing Known Problems

Michigan law requires sellers to complete a Seller's Disclosure Statement listing known material defects. Some sellers are tempted to "forget" about the basement that floods every spring or the roof that's been leaking for years. This is a mistake. If the buyer discovers undisclosed defects after closing, you could face legal liability. Failing to disclose doesn't just create legal risk — it can kill a deal when the buyer's inspection inevitably finds the issue. Cash buyers expect properties to have issues and factor them into the offer. Honesty is faster, safer, and legally required. See our guide on Michigan Seller Disclosure Requirements.

Mistake #7: Choosing the Wrong Path for Your Timeline

If you need to close in 30 days or less — because of a job relocation, foreclosure, or another deadline — a traditional listing is rarely the right choice. Even if a buyer makes an offer quickly, financing, appraisals, and inspections can stretch the process to 45–60+ days. And there's always the risk the buyer's financing falls through. If time matters, a cash sale is typically the only path that guarantees a fast, certain close. Read more: How Long Does It Take to Sell a House?

Mistake #8: Underestimating the Emotional Toll

Selling a home — especially one you've lived in for years or inherited from a loved one — is emotionally draining. Adding contractor management, staging, showings, and open houses on top of that can be overwhelming. Many sellers underestimate this burden and find themselves burned out before closing. If you're already dealing with a difficult life event (divorce, death in the family, health issues), a cash as-is sale can dramatically reduce the emotional weight by eliminating showings, repairs, and uncertainty.

Mistake #9: Not Comparing All Options

The biggest mistake of all? Assuming there's only one way to sell your home. You have options: list with a traditional agent, sell to a cash buyer, sell for-sale-by-owner (FSBO), sell to an iBuyer, or even keep the home as a rental. Each path has different timelines, costs, and tradeoffs. The seller who explores multiple options before deciding almost always ends up with a better outcome than the seller who goes with the first option they're presented.
