Real Estate Investment Analysis: The Complete Guide
Real estate investment analysis is the process of evaluating a property to determine whether it will be profitable under your intended strategy. Whether you are flipping, renting, wholesaling, or doing BRRRR, the analysis process determines your maximum purchase price, expected returns, and risk profile. This guide covers every metric and method you need to analyze deals with confidence.
The five numbers that matter
Every investment analysis starts with five core numbers. Get these right and the rest follows:
- After Repair Value (ARV). What the property will be worth in renovated condition. This anchors every other calculation.
- Purchase price. What you will pay for the property.
- Repair costs. What the renovation will cost. Include a 10-15% contingency.
- Holding costs. Monthly costs while you own the property: loan payments, insurance, taxes, utilities, and property management if applicable.
- Exit costs. Costs to sell: agent commissions (5-6%), closing costs (1-2%), and transfer taxes.
Analysis by strategy
Fix and flip analysis
The flip analysis is straightforward: profit = ARV - purchase price - repairs - holding costs - selling costs. Use the 70% rule as a quick filter (max purchase = ARV x 70% - repairs). Then run a detailed analysis with realistic holding period (typically 4-6 months), actual financing costs (hard money at 10-14%), and selling timeline estimates.
Flip example: ARV: $300,000 | Purchase: $180,000 | Repairs: $45,000 | Holding (5 mo): $10,000 | Selling costs: $21,000
Projected profit: $44,000 (14.7% ROI on total investment)
Rental property analysis
Rental analysis focuses on cash flow and long-term returns. Key metrics include monthly cash flow (rent minus all expenses), cash-on-cash return (annual cash flow / total cash invested), cap rate (NOI / purchase price), and gross rent multiplier (purchase price / annual rent). A good rental deal produces at least $200-$300/month cash flow per unit after all expenses.
Wholesale analysis
For wholesaling, you analyze the deal from your buyer's perspective. If the deal does not work for a flipper or landlord at your asking price, it will not sell. Your job is to verify the ARV, estimate repairs, and confirm that your buyer can make a profit after paying your contract price plus assignment fee.
Common analysis mistakes
- Cherry-picking comps. Using only the highest comps to justify a deal. Always use a range and weight the most similar comps more heavily.
- Ignoring holding costs. Especially on flips, holding costs can consume thousands per month. Failing to account for them inflates projected profit.
- Underestimating repairs. The most common and most expensive mistake. Get contractor bids before committing, not after.
- Assuming best-case scenarios. Build your analysis around conservative assumptions. If the deal only works if everything goes perfectly, it is too risky.
Tools for faster analysis
Modern deal analysis platforms use AI to accelerate the process. AI-powered comp selection pulls recent sales and scores them for relevance. Photo-based repair estimation analyzes property condition from images. And automated cash flow projections model multiple scenarios (best case, base case, worst case) simultaneously. Deal Run combines these capabilities so you can evaluate deals in minutes rather than hours.
