Scenario-Based Recommendations

First-Time Homebuyers

Best Choice: Conventional Loan

• Smaller reserve requirements
• First-time buyer programs available
• Lower overall barriers to entry

Example: Sarah is purchasing a $450,000 home. With 5% down ($22,500) and a 680 credit score, she qualifies for a conventional loan but wouldn’t meet jumbo standards.

Luxury Property Purchase

Best Choice: Jumbo Loan

Reasons:

• Loan amount exceeds conforming limits
• Single mortgage simplifies structure
• Competitive rates for qualified borrowers
• Access to portfolio lender programs
• Relationship banking opportunities

Example: Michael is purchasing a $2.1 million home in Los Angeles. Even with the high-cost area limit of $1,149,825, he needs a jumbo loan for the remaining $950,175+ (with 20% down).

Move-Up Buyers

Best Choice: Depends on loan amount

Conventional Loan Scenario:
