What is the 1% rule in real estate?

The 1% rule states that monthly rent should equal at least 1% of the purchase price. A $200,000 property should rent for at least $2,000/month. This is a quick screening tool, not a definitive analysis — many good deals fall slightly below 1%.

How many properties should I analyze before buying?

Most successful investors analyze 50-100 deals for every one they purchase. This sounds like a lot, but with practice the initial screen takes under 5 minutes. Deep analysis on the best candidates takes 30-60 minutes. The more deals you analyze, the better your instincts become.

What is the most important metric for rental property?

DSCR is arguably the most important single metric because it tells you whether the property can sustain itself financially. If DSCR is below 1.0, every other metric is irrelevant — you are losing money. After DSCR, cash on cash return tells you how hard your invested capital is working.

The 5-Minute Property Screen

Before doing a deep analysis, screen properties quickly using two rules. The 1% Rule: Monthly rent should be at least 1% of the purchase price. A $150,000 property should rent for at least $1,500/month. The 50% Rule: Assume 50% of gross rent goes to operating expenses (taxes, insurance, maintenance, vacancy, management). If $1,500 rent means $750 in expenses and $750 left for mortgage payment, can the deal work? These rules are rough filters — not final analysis — but they eliminate 80% of bad deals in seconds.

Step 1: Determine Market Rent

Research what similar properties in the area actually rent for. Use Zillow Rental Manager, Rentometer, Craigslist, and Facebook Marketplace. Look at comparable properties with similar bedrooms, bathrooms, square footage, and condition. Talk to local property managers. Do not use the seller listing rent estimate — it is often inflated. Be conservative: use the lower end of the comparable range for your analysis.

Step 2: Calculate NOI

Net Operating Income = Annual Gross Rent minus Operating Expenses. Include: property taxes (verify with county assessor), insurance (get a quote), vacancy allowance (5-10%), maintenance (1% of value or $100/unit/month), property management (8-10% even if self-managing — your time has value), and any HOA or utilities you pay. A realistic expense ratio is 40-50% of gross rent for residential properties.

Step 3: Analyze Financing

Calculate your monthly mortgage payment based on the loan amount, interest rate, and term. Then calculate DSCR (NOI divided by annual mortgage payments) and cash flow (NOI minus mortgage payments). A DSCR above 1.25 and positive monthly cash flow are minimum targets for most buy-and-hold investors.

Step 4: Calculate Returns

Cap Rate = NOI / Purchase Price. Cash on Cash = Annual Cash Flow / Total Cash Invested. These two metrics let you compare this deal against other investments. Target at least 6% cap rate and 8% cash on cash for cash flow markets. In appreciation markets, you may accept lower numbers if the growth outlook is strong.

Step 5: Stress Test

Before making an offer, ask: What happens if rent drops 10%? What if vacancy is 15% instead of 5%? What if a major repair costs $5,000? If the property still has positive cash flow under stress, it is a resilient investment. If one bad month puts you underwater, the margins are too thin. becvio Stress Test lets you model these scenarios across your entire portfolio automatically.
