- 01Research follows a funnel: start with broad market selection (job growth, population trends), then narrow to neighborhoods, then filter individual properties
- 02The 1% rule is your first-pass filter: if a $250,000 property can't rent for at least $2,500/month, move on
- 03The 50% rule estimates your operating expenses at half of gross rent — so $3,000/month rent means ~$1,500 in taxes, insurance, maintenance, and vacancy
- 04Off-market deals (driving for dollars, wholesalers, REIA meetups) often beat MLS listings because there's less competition and more room to negotiate

I'm Martin Maxwell. The number one reason first-time investors lose money isn't bad tenants or unexpected repairs — it's buying in the wrong market. Wrong neighborhood. Wrong price point. They fell in love with a property instead of the numbers. Today we're covering the Research phase: how to turn "this feels like a good deal" into "here's the math to prove it."
The Research Funnel: Wide to Narrow
Research is a funnel. You start wide and narrow down to specific addresses.
Market selection comes first. You're looking at macro indicators: job growth above 2% annually, population growth, diversified economy, landlord-friendly laws, and a rent-to-price ratio that makes the math work. If the median home price is $500,000 and the median rent is $2,000, that's a 0.4% ratio — well below the 1% threshold.
Neighborhood selection zooms in. Compare areas by vacancy rate, median rent, school ratings, crime trends, and proximity to employment centers. A 12% vacancy rate is a warning sign. The sweet spot is B-class neighborhoods — working professionals, stable tenancy, numbers that pencil out.
Property filtering is where the quick-math rules earn their keep.
The 1% Rule: Your First-Pass Filter
The 1% rule is the fastest way to screen a deal. Can the property rent for at least 1% of the purchase price per month?
- $200,000 property needs $2,000/month or more
- $150,000 property needs $1,500/month or more
- $350,000 property needs $3,500/month or more
If it clears 1%, it's worth a deeper look. If it doesn't, you're probably looking at negative cash flow once all expenses are factored in. A couple of caveats: the 1% rule is a screening tool, not a decision tool. Some properties clear 1% but have massive deferred maintenance. In high-cost markets like the Bay Area or Denver, almost nothing clears 1% — that doesn't mean you can't invest there, but you need a different strategy.
The 50% Rule: Estimating Real Expenses
Beginners almost always underestimate expenses. The 50% rule says roughly half of your gross rent goes to operating expenses — not the mortgage, but taxes, insurance, maintenance, vacancy reserves, property management, and capital expenditure reserves.
A $2,400/month rental on a $200,000 property:
- Gross annual rent: $28,800
- Operating expenses (50%): $14,400
- NOI: $14,400
- Annual mortgage payment ($160,000 loan at 7%): $12,768
- Annual cash flow: $1,632 ($136/month)
$136/month isn't exciting — but it's positive cash flow while a tenant pays down your $160,000 mortgage. That cap rate? $14,400 / $200,000 = 7.2%. Solid.
Where to Find Deals
Once you know what to look for, you need a pipeline. The MLS (Zillow, Redfin, Realtor.com) has the most inventory but the most competition. Wholesalers find distressed properties and assign contracts to investors — verify the numbers independently. Driving for dollars means scouting target neighborhoods for distressed properties, looking up owners on the county assessor's site, and sending letters. REIA meetups let you trade leads with other investors. One relationship with a wholesaler or fellow investor can feed your pipeline for years.
Building Your Deal Pipeline
The discipline that separates researchers from owners: analyze deals every single week. Five per week. Purchase price, estimated rent, expenses (50% rule), mortgage payment, cash flow, cap rate, cash-on-cash return. After a month of reps, you'll spot a good deal in seconds because you trained on data, not gut feeling.

Cap rate measures a property's annual net operating income as a percentage of its purchase price or current market value, assuming an all-cash purchase.
Read definition →Monthly rent should hit at least 1% of what you paid. That's the 1% rule. A $185,000 house? $1,850/month or more. Quick screen — not a full analysis.
Read definition →The percentage of time a rental property sits empty and produces no income, calculated as vacant units divided by total units — the silent profit killer in rental investing.
Read definition →NOI (net operating income) is what a property earns from operations each year. Rental revenue minus vacancy loss and operating expenses. Before you subtract the mortgage, CapEx, or taxes.
Read definition →Cash-on-cash return measures your annual pre-tax cash flow as a percentage of the total cash you actually invested in a property.
