💬 Real Stories from Reddit
"Inspector found horizontal cracks in basement, doors that wouldn't close, and sloping floors. Got a structural engineer - $80K foundation repair needed. Walked away. Seller ended up selling for $100K less to a flipper."
Trust the red flags. The right house is out there.
"Inspection found 20-year-old roof with 2-3 years left, outdated electrical panel, and HVAC on its last legs. Got quotes: $18K roof, $3K panel, $8K HVAC. Negotiated $20K credit. Closed and fixed everything ourselves for $22K."
Get quotes, negotiate credits, and control the repairs yourself.
"Inspector noted 'minor water staining in basement.' We ignored it. First big rain, basement flooded. Turns out there was a major drainage issue. Spent $15K on waterproofing. Should have investigated more."
Water issues are NEVER minor. Always investigate further.
🤝 How to Negotiate After Inspection
Strategy 1: Request Repairs
Ask seller to fix issues before closing. Best for: safety issues, code violations. Risk: seller may do cheap/poor quality work.
Strategy 2: Request Credit at Closing
Get money back at closing to do repairs yourself. Best for: major systems, when you want control. Get multiple quotes to justify amount.
Strategy 3: Price Reduction
Lower the purchase price. Best for: large issues. Note: affects your loan amount and may require new appraisal.
Strategy 4: Home Warranty
Ask seller to pay for 1-year home warranty ($400-$600). Covers major systems if they fail. Good for older homes with aging systems.
