How to Analyze Real Estate Deals: A Step-by-Step Guide

Successful real estate investing comes down to one skill above all others: the ability to analyze deals quickly and accurately. Whether you're buying your first rental or your fiftieth flip, the math needs to work. Here's the framework professional investors use to evaluate opportunities.

The 70% Rule for Fix & Flips

The 70% rule is a quick formula to determine if a flip makes sense: Your maximum offer should be 70% of the ARV (after-repair value) minus repair costs. For example, if a property will be worth $250,000 after $40,000 in renovations, your max offer is $250,000 × 0.70 - $40,000 = $135,000.

This formula accounts for closing costs, holding costs, financing costs, and profit margin. In competitive markets, you might stretch to 75% or 80%, but going higher significantly increases your risk.

Cap Rate for Rental Properties

Cap rate (capitalization rate) measures a rental property's return if you paid all cash: Cap Rate = Net Operating Income ÷ Property Value. A property generating $15,000 annual NOI worth $200,000 has a 7.5% cap rate.

In most markets, 5-8% is typical for residential rentals. Higher cap rates often mean higher risk or lower appreciation potential. Lower cap rates typically indicate premium locations with better appreciation prospects.

Cash-on-Cash Return

Cash-on-cash return measures your actual return on invested capital: Annual Cash Flow ÷ Total Cash Invested. If you invest $50,000 and generate $6,000 annual cash flow, your cash-on-cash return is 12%.

This metric is especially important when using financing. A property with a low cap rate might still produce excellent cash-on-cash returns if you're leveraging wisely.

The 1% Rule (and Why It's Limited)

The 1% rule says monthly rent should be at least 1% of the purchase price. A $150,000 property should rent for $1,500/month minimum. It's a quick screening tool, but don't rely on it alone—expenses vary dramatically by property age, location, and condition.

Analyzing Expenses Accurately

• Property taxes (check actual rates, not estimates)
• Insurance (get actual quotes)
• Property management (8-10% of rent)
• Vacancy allowance (5-10% depending on market)
• Maintenance and repairs (5-10% of rent, more for older properties)
• HOA fees if applicable
• Utilities you'll pay

Red Flags to Watch For

• Properties priced significantly below comps—there's usually a reason
• Unpermitted additions or structural issues
• High HOA fees that eat cash flow
• Declining neighborhood indicators (vacancy rates, crime)
• Sellers who won't allow inspections
• Properties in flood zones or other high-risk areas
