⚠️ Common Mistakes to Avoid

▼
❌ Using your current rent
Use rent for similar property in target area, not your current place
❌ Ignoring mobility needs
If you might move in 3-5 years, renting is usually better regardless of numbers
❌ Forgetting maintenance costs
Budget 1-3% of home value annually for repairs and maintenance
❌ Not considering opportunity cost
Money in down payment could earn 8-10% in stock market

🚀 Pro Tips for Better Results

▼
💡 Location matters more than timing
Buy in areas with good schools, job growth, and limited housing supply
💡 Consider total lifestyle costs
Suburban homes may need cars, urban condos have HOA fees
💡 Plan for rate changes
If rates drop 1-2%, refinancing can dramatically improve your position
💡 Emergency fund is crucial
Keep 6+ months expenses after down payment for unexpected repairs
