The biggest mistake home sellers make is overpricing their home, especially in a stabilizing market, as it causes properties to sit longer, become less appealing, and ultimately sell for less than they would have if priced correctly from the start. Other significant errors include skipping necessary repairs (like roofs or foundation issues), poor staging/cleaning, and failing to price according to current market realities rather than pandemic-era highs.

What is the biggest red flag in a home inspection?

The biggest home inspection red flags involve costly structural, water, electrical, and pest issues, including foundation cracks, sloping floors, major water intrusion (roof/basement), active leaks, outdated/unsafe electrical systems (knob & tube, aluminum wiring, overloaded panels), and pest infestations (termites, rodents), as these threaten safety and incur significant repair bills. Fresh paint, strong odors, and improper grading are also major warnings, often masking deeper problems. 

What is the most common reason a property fails to sell?

The most common reason a property fails to sell is overpricing, as it deters buyers, causes financing issues (appraisals), and makes the home seem undesirable as it sits on the market longer than comparable properties. Other major factors include poor presentation (bad staging, unprofessional photos, lack of curb appeal), ineffective marketing, poor condition, or a bad location, but price is almost always the primary barrier. 

What not to say when selling a house?

When selling a house, avoid saying you're in a hurry, have personal problems (divorce, illness), the house has issues (leaks, pests), or that it's in "perfect" or "as-is" condition, as this weakens your negotiating power; also, keep comments about price, offers, or your bottom line to yourself, focusing instead on positive features. Never lie about known defects, but strategically avoid revealing personal circumstances that signal desperation or highlighting flaws that could be discovered later, like undisclosed foundation issues.
 

What is the rule of 3 when buying a house?

What not to tell your realtor?

You should not tell your realtor your absolute bottom line price, sensitive financial details (income, savings, credit score), or personal reasons for selling (like divorce or financial hardship) as this can weaken your negotiation power; sellers must disclose known material defects but shouldn't badmouth their home or community, while buyers should avoid saying they love a place or that they have an urgent deadline.

How much mortgage can I get with $70,000 salary?

With a $70,000 salary, you can generally afford a house in the $210,000 to $350,000 range, but this heavily depends on your down payment, credit score, and existing debts; lenders look for monthly housing costs under $1,633 (28% of gross income) and total debts under $2,100 (36% of gross income). A larger down payment and lower debts allow you to afford a more expensive home, while high interest rates decrease your buying power.

A strong credit score could help you secure a lower mortgage rate. You generally need a credit score of at least 620 to qualify for a conventional mortgage, though every lender is different.

You likely cannot comfortably afford a $500k house on a $100k salary, as general guidelines suggest needing closer to $120k-$160k income, with a $100k salary usually fitting a $350k-$400k home due to the 28/36 rule (housing costs under 28% of gross income). While lenders might approve a larger loan, it depends heavily on your existing debt, credit score, down payment, interest rates, and local taxes/insurance, which can strain your budget and leave you house-poor.
