Frequently Asked Questions

What's a good cash flow for rental property?

Aim for minimum $100-200 per unit monthly positive cash flow. Experienced investors often target $300-500+ per unit for better returns and risk buffer.

How much should I budget for maintenance?

Rule of thumb: 1% of property value annually for maintenance, or 10% of rent income. Older properties may need 15-20% for higher maintenance costs.

Should I include vacancy in calculations?

Yes, always include vacancy. Conservative investors use 10% vacancy rate, while optimistic investors might use 5%. This accounts for turnover periods between tenants.

What cap rate should I look for?

Depends on location and property type. Generally: 5-8% for stable areas, 8-12% for higher-risk/value-add properties, 12%+ for opportunistic investments.
