Many new investors underestimate monthly costs because they stop at PITI.

Step 1: Understand PITI

PITI includes:

● Principal

● Interest

● Property Taxes

● Insurance

Investopedia provides a clear explanation: https://www.investopedia.com/terms/p/piti.asp

Step 2: Add Operating Expenses

In the Santa Barbara real estate market, realistic expense assumptions include:

• HOA dues (if applicable) • Property management (8–10%) • Maintenance (5–10%) • Vacancy reserve (5–8%) • Capital expenditures • Utilities • Landscaping

Step 3: Build Reserves

Strong investors set aside monthly reserves for unexpected repairs.

Step 4: Stress-Test the Deal

Ask: • What if rent drops? • What if vacancy increases? • What if rates don’t fall? 

Why This Matters in Santa Barbara

Higher price points mean smaller margins. Accurate expense projections separate long-term investors from speculative ones.
