Use this quick rent-to-price test to screen a rental property—then look deeper at loan costs, vacancy, maintenance and local market conditions.
The 1% Rule in Real Estate is a quick rule of thumb used by some rental-property investors to decide whether a property deserves a closer look. It compares the expected monthly rent with the property’s purchase price. It is not a guarantee of profit, and a property that passes the test can still lose money after expenses.

The video’s main takeaway is that the 1% rule is a quick first filter, and that interest rates and the purchase price can make a major difference. Use the calculation to shortlist properties, then run a complete cash-flow and due-diligence review.

What Is the 1% Rule in Real Estate?
The 1% Rule in Real Estate is useful as an initial filter when comparing rental properties, but it should always be followed by a detailed review of the property and its costs.
The rule says that a rental property’s expected monthly rent should be approximately 1% of its purchase price. For example, a property costing ₹20,00,000 would need rent of about ₹20,000 per month to meet the simple benchmark. If the same property could rent for only ₹12,000 a month, it would not pass this first-pass screen.
The video accompanying this guide calls it the “100 times rent rule”: multiply monthly rent by 100 to get the rough maximum purchase price suggested by the rule. The idea is to do a fast calculation before spending time on a full investment analysis.
How to Calculate the 1% Rule
Use either of these equivalent formulas:
Monthly rent test: Monthly rent ÷ Purchase price × 100 = rent-to-price percentage
Price test: Monthly rent × 100 = rough maximum purchase price
For example, if the expected rent is ₹18,000 per month, the 1% rule points to a price of about ₹18,00,000 (₹18,000 × 100). If the property is listed at ₹24,00,000, the rent-to-price ratio is 0.75%—below the rule’s benchmark.
| Purchase price | Monthly rent | Rent-to-price ratio | Quick result |
|---|---|---|---|
| ₹15,00,000 | ₹15,000 | 1.00% | Meets the rule |
| ₹20,00,000 | ₹16,000 | 0.80% | Below benchmark |
| ₹25,00,000 | ₹25,000 | 1.00% | Meets the rule |
| ₹30,00,000 | ₹20,000 | 0.67% | Below benchmark |
Try the 1% Rule Calculator
Enter a property’s price and realistic monthly rent. The calculator checks the ratio and also estimates a simple monthly cash flow after the costs you enter and an optional loan payment. This is an estimate, not a property valuation or loan offer.
This property meets the 1% benchmark before a full investment review.
Monthly costs should account for realistic maintenance, vacancy allowance, society charges, property tax, insurance and management. Add purchase and repair costs to your own analysis; they are not automatically included here.
Why the Rule Is Only a Starting Point
The source video explains that financing costs can change the outcome substantially. When interest rates are higher, the monthly loan payment may consume more of the rent. At a lower rate, the same property and rent may produce a more comfortable cash flow. That is why passing the 1% test is not enough to decide whether to buy.
Also remember that the simple rule compares gross rent with purchase price. It does not directly calculate net operating income, tax, vacancy, repairs, major replacements, brokerage, stamp duty, registration or the cost of renovating a property. A property may meet the ratio and still have negative cash flow after these costs.
How to Use the 1% Rule for Indian Property
The rule is a US-origin rule of thumb, and the video uses examples from Florida and other US markets. Do not assume its examples for mortgage rates, insurance, property taxes or rents apply in India. Indian property prices, rental yields, registration costs, financing terms and local regulations vary widely between cities and even neighbourhoods.
For an Indian property, start with local evidence: compare similar homes actually available for rent, check how long listings remain vacant, and estimate all recurring and one-time costs. Then compare the expected net rent with your loan repayment and the return you could seek from alternative uses of your capital. A high-value property in a low-rent neighbourhood may fail the 1% rule while still having other investment characteristics; conversely, a high ratio does not automatically mean a good deal.
What About Buying Below Market Value?
The video also discusses buying a property below market value, repairing it, renting it and refinancing it. The underlying idea is that a lower purchase cost or a well-managed renovation may improve the rent-to-price ratio. But this approach brings its own risks: repair budgets can overrun, hidden defects can appear, refinancing is not guaranteed, and a future valuation may be lower than expected.
Before pursuing a renovation or refinance strategy, get an independent property inspection, realistic contractor estimates and a financing plan that still works if rent is lower or the property stays vacant. Do not rely on an assumed future valuation to make today’s purchase affordable.
When the 1% Rule in Real Estate May Mislead You
The 1% Rule in Real Estate can make a property look attractive when the advertised rent is unusually high, the property needs major repairs, or the estimate ignores months without a tenant. Verify rent using comparable properties and allow for vacancy before trusting the result.
Likewise, the 1% Rule in Real Estate does not compare every possible investment or predict future appreciation. Use it alongside net rental yield, estimated cash flow, property condition and your own financial goals.
Practical Checklist Before You Buy
- Use a realistic rent estimate based on comparable properties, not just an optimistic listing.
- Calculate the rent-to-price ratio, but treat it as a screening metric rather than a decision rule.
- Estimate vacancy, repairs, maintenance, taxes, insurance, society charges and management fees.
- Calculate the loan EMI and check whether rent can cover the full costs with a buffer.
- Include purchase costs and any immediate renovation in the total amount invested.
- Stress-test the deal for higher interest costs, lower rent and unexpected repairs.
- Check title, approvals, applicable local rules and tax implications with qualified professionals.
Frequently Asked Questions
Does the 1% Rule guarantee a profitable rental property?
No. It compares gross monthly rent with the purchase price. It does not account for every expense, vacancy, financing cost or future change in the market.
What is the 100 times rent rule?
It is another way to describe the same rough benchmark: multiply expected monthly rent by 100 to estimate the maximum price that meets a 1% rent-to-price ratio.
Should every Indian property investor use the 1% Rule?
No single rule suits every market or investment goal. Use it as an initial screen, compare local rental yields and evaluate cash flow, risk, liquidity and all transaction costs before investing.
What if a property does not meet the 1% Rule?
It may be worth rejecting, negotiating a lower price or examining whether the rent estimate is realistic. Do not stretch assumptions or ignore costs just to make the property pass.
