Expert Loan Planning Strategies

1

Apply the 80% rule - only use 80% of maximum affordability as your target to create financial safety buffer

2

Follow the 28/36 rule: housing costs ≤ 28% of gross income, total debt ≤ 36% of gross income

3

Compare at least 3-4 different scenarios across interest rates and terms to optimize total cost

4

Calculate Total Cost of Ownership including prepayment penalties, insurance, taxes, and maintenance costs

5

Build interest rate sensitivity analysis: each 0.5% rate increase typically reduces borrowing capacity by 5-8%

6

Time your loan application optimally: avoid year-end when lenders tighten credit standards

7

Prepare DTI ratio (Debt-to-Income) below 43% to achieve highest approval rates with best terms

8

Consider bi-weekly payments instead of monthly - saves 15-20% in total interest over loan life
