Red Flags That Should Concern You

Walk away or negotiate hard if you find:

• Active foundation movement or major cracks

• Knob-and-tube or aluminum wiring throughout

• Multiple HVAC systems near end of life

• Extensive mold or water damage

• Roof needing immediate replacement

• Sewage line problems

• Extensive termite damage

• Illegal additions or unpermitted work

After the Inspection Review the Report

• Read entire report carefully

• Categorize issues: Major, moderate, minor

• Get repair estimates for major items

• Calculate total repair costs

Negotiation Strategies

• Request seller make repairs

• Request closing cost credit

• Reduce purchase price

• Walk away if too much

Focus negotiations on major items (roof, HVAC, foundation, plumbing, electrical). Don't nickel-and-dime on minor cosmetic issues.

Creating Your Repair Budget

After inspection, create detailed budget:

• Critical repairs (safety/habitability): $X

• Important repairs (prevent deterioration): $Y

• Deferred maintenance: $Z

• Cosmetic updates: $W

Add 20% contingency for hidden issues.

Inspection Tips for Investment Properties

• Focus on major systems and structural issues

• Cosmetic problems are easy/cheap to fix

• Evaluate remaining useful life of major components

• Calculate when you'll need to replace roof, HVAC, etc.

• Budget for deferred maintenance

A thorough inspection is your best defense against buying someone else's expensive problems. Spend the time and money to inspect properly—it always pays off.
