Real Estate ROI & 70% Rule Calculator

With borrowing costs higher than in previous years, a "good" cap rate is generally relative to the interest rate environment. In 2026, investors often look for cap rates of 6% to 8%+ in secondary and tertiary markets to ensure positive leverage. In high-appreciation coastal markets, cap rates might still hover around 4% to 5%.

Cash-on-Cash Return measures the annual pre-tax cash flow divided by the actual cash invested out of pocket (down payment + closing costs + rehab). ROI (Return on Investment) is a broader term that accounts for total wealth generated, including loan principal paydown, property appreciation, and tax benefits, divided by total investment.

Under Section 1031 of the IRS tax code, real estate investors can defer paying capital gains taxes on the sale of an investment property if they reinvest the proceeds into a new "like-kind" property. It is one of the most powerful wealth-building tools in US real estate.

Investors often favor landlord-friendly states with strong job growth, population influx, and lower property taxes. Popular Sun Belt markets include Texas, Florida, Tennessee, and Arizona, as well as parts of the Midwest where housing is highly affordable (like Ohio and Indiana).

Many investors place their properties in a Limited Liability Company (LLC) to protect their personal assets from lawsuits related to the property. However, forming an LLC involves setup fees, annual state fees, and can complicate getting a conventional Fannie Mae mortgage. Discuss with a CPA and real estate attorney.

Yes, property taxes are a critical component of Net Operating Income (NOI) and cash flow calculations. US property taxes vary wildly by state and county (from under 0.5% in parts of Hawaii to over 2.5% in New Jersey). Our calculator deducts property taxes as a monthly operating expense before calculating cash flow and ROI.

The 1% Rule states that a rental property should generate at least 1% of its total purchase price in gross monthly rent to be considered a viable cash-flowing asset. For example, a $250,000 house should rent for at least $2,500 a month. In modern expensive markets, hitting this rule often requires investing in secondary cities.

The IRS allows residential property owners to depreciate the value of the building (but not the land) over 27.5 years. This non-cash deduction significantly lowers your taxable rental income, shielding your cash flow from income taxes and boosting your true after-tax ROI.

GRM is calculated by dividing the property purchase price by the gross annual rental income. A lower GRM indicates a better potential investment. For instance, a property costing $300,000 that generates $30,000 annually has a GRM of 10. Most investors target a GRM between 8 and 12.

Conservative underwriting usually models a vacancy rate between 5% and 8% of gross scheduled income. This accounts for the time a property sits empty between tenants and the cost of turning over the unit (cleaning, painting, minor repairs).

BRRRR stands for Buy, Rehab, Rent, Refinance, Repeat. Investors buy a distressed property below market value, fix it up, rent it out, and then do a cash-out refinance to pull their initial capital back out. They then use that capital to buy the next property, scaling their portfolio with infinite ROI.

Professional property management typically costs 8% to 10% of gross monthly rent. While it reduces your immediate cash-on-cash return, it turns the investment into truly passive income and often pays for itself by reducing vacancy times, handling evictions legally, and retaining long-term tenants.

NOI is the total revenue generated by a property minus all operating expenses (property taxes, insurance, maintenance, HOA, management fees). Crucially, NOI does not include the mortgage principal and interest payment. It is the purest measure of a property's operational profitability.

The 50% rule is a quick estimation tool stating that operating expenses (excluding the mortgage) will typically consume 50% of the gross rental income. If a property rents for $2,000 a month, expect to spend $1,000 on taxes, insurance, vacancy, and repairs, leaving $1,000 for your debt service and profit.

Maintenance covers minor, routine repairs (like fixing a leaky faucet or replacing a doorknob). Capital expenditures (CapEx) are major replacements that extend the life of the property, such as a new roof, HVAC system, or foundation repair. Investors should set aside separate reserves for CapEx.

House hacking involves buying a multi-family property (like a duplex or triplex) or a home with extra bedrooms, living in one unit, and renting out the others. The rent from tenants covers most or all of the mortgage, allowing the investor to live for free while building equity.

When you sell a rental property, the IRS requires you to pay taxes on the depreciation you claimed (or could have claimed) during the years you owned it. This "recapture" is taxed at a maximum rate of 25%. A 1031 Exchange can defer this tax.

Short-term rentals can generate significantly higher gross revenue than long-term rentals, often doubling or tripling the income. However, they also come with much higher operating expenses (cleaning, furnishing, utilities) and are subject to strict, changing municipal regulations and higher vacancy risks.

Leverage means using borrowed capital (a mortgage) to buy an asset. If you buy a $100,000 property with $20,000 down, and it appreciates by 5% ($5,000), your return on your actual cash invested is 25%, not 5%. Leverage amplifies both gains and cash-on-cash returns.

A turnkey property is a home that has already been fully renovated, has a tenant in place, and is managed by a property management company. It is completely ready for a passive investor. Because the risk and work have been removed, turnkey properties usually offer slightly lower ROI than value-add properties.
