The 90-Second Rule That Exposes Most Indianapolis Wholesale Deals

The email hits your inbox at 7 a.m. Caps lock. Exclamation points. A zip code you recognize. A rent figure that sounds strong. A price that sounds like a bargain. And somewhere in the subject line, something about the 1% rule.

If you have been investing in Indianapolis rental properties for any length of time, you have seen a hundred versions of this email. Most of them are not deals. Some of them are bad deals dressed up with just enough math to sound plausible. A few of them will cost an unsuspecting investor real money.

Here is the single calculation that tells you in about 90 seconds whether a wholesale listing is worth your time to investigate further.

The Half-the-Rent Rule

Take the monthly rent. Multiply by 12. Cut that number in half. Divide by the purchase price. If the result is not at least 0.08, meaning 8% cap rate, keep scrolling.

That is it. That is the screen.

One important boundary before going further. This threshold is calibrated for lower-income urban core rentals in Indianapolis zip codes like 46201, 46218, 46219, 46222, and 46227. Class A and B properties in Fishers, Carmel, and Noblesville carry different expense profiles, different turn costs, and different placement cost patterns. They require separate analysis and a different cap rate threshold. If you are evaluating a higher-end suburban rental, the numbers in this article do not apply directly.

The math works because operating expenses on a lower-income urban core single-family rental in Indianapolis consistently run between 48% and 57% of gross rent when you account for vacancy, repairs, property management, taxes, insurance, and miscellaneous costs. Cutting gross rent in half gives you a conservative estimate of net operating income before debt service. Dividing that by purchase price gives you a rough cap rate. A number below 8% on this asset class, in this market, means the deal does not generate adequate return for the risk and management intensity involved.

This is not a replacement for full underwriting. It is a filter that lets you reject bad deals in the time it takes to read the listing.

Always Divide by Your All-In Cost, Not the Purchase Price

This is the step wholesalers are counting on you to skip. The number in the denominator is not the purchase price. It is everything you will spend before the property is stabilized and producing rent.

All-in cost means purchase price plus estimated rehab plus closing costs. If a wholesale listing shows a $100,000 purchase price but the property needs $20,000 in work before it can be rented, your denominator is $120,000, not $100,000. Running the screen on the purchase price alone produces a false result and a false sense of confidence.

Here is what that looks like in practice. Purchase price $100,000, rehab $20,000, all-in cost $120,000, rent $1,200 per month. Gross annual rent is $14,400. Cut in half: $7,200. Divide by $120,000: a 6% cap rate. That deal fails the screen. To clear 8% at $120,000 all-in, the property needs to rent for $1,600 per month. That is a very different conversation than the headline purchase price suggests.

Wholesale listings almost always quote the purchase price in the subject line and mention the required work somewhere in the body copy, often framed as upside or value-add potential. The half-the-rent rule only works if you add those numbers together before you divide.

What Goes Into That 50%

The expense stack for a typical Indianapolis urban core rental breaks down roughly as follows, expressed as a percentage of gross annual rent:

• Vacancy: 8%
• Repairs and maintenance: 10%
• Property management: 10%
• Accounting and miscellaneous: 3%
• Property taxes: varies, typically 10 to 16% depending on assessed value
• Insurance: varies, typically 4 to 6%

Total operating expenses land between 45% and 57% depending on the specific property, assessed value, and rent level. Cutting gross rent in half sits in the middle of that range and gives you a conservative working figure without requiring you to know the exact tax bill or insurance quote.

The number that surprises most out-of-state investors is taxes. Indiana property taxes run approximately 2% of assessed value annually. On a property assessed at $110,000, that is $2,200 per year. Against a $1,200 monthly rent, or $14,400 annually, taxes alone represent more than 15% of gross income. Add insurance at $800 per year and you are at nearly 21% just for taxes and insurance, before a single repair or vacancy day.

Run It on a Real Ad

Here is a real wholesale listing pulled from an Indianapolis investor group, reproduced as written:

Indy 46218 – 1% RULE CRUSHER
3bd/1ba, 1845sqft + fenced lot. Rent $1.2k+ = 12%+ cashflow Value-add flip = quick equity pop. Easily Make into 4+ Beds! RENT NOW or FLIP Later!! Strong cash offer = yours. Comps exploding. Don’t blink. Close fast. ONLY $110k OBO

Apply the half-the-rent rule.

Gross annual rent at $1,200 per month: $14,400. Cut in half: $7,200. Divide by $110,000: a 6.5% cap rate.

That is below the 8% threshold. At $1,200 per month, this is not a deal at $110,000.

The listing claims 12% cashflow. What it is actually quoting is gross yield, meaning $14,400 divided by $110,000. That is 13% gross, before a single dollar of operating expense is touched. Gross yield and cap rate are not the same number. Gross yield ignores expenses entirely. Cap rate, which is what the half-the-rent rule approximates, accounts for them. Calling a 13% gross yield “12% cashflow” skips the step that determines whether the property actually makes money. Either it is a math error or a sales tactic. Either way, the investor pays for it.

The only scenario where the half-the-rent rule clears 8% on this listing is if rent actually reaches $1,470 per month. In zip code 46218, a 3 bed/1 bath property hitting $1,470 in the current market is not a given. It is an assumption that needs to be verified against actual lease comps before it belongs in any underwriting model.

For context on what Indianapolis rents are actually doing right now, the Marion County Rental Market Report for Q1 2026 shows days on market running 40 to 52% longer year-over-year, which means optimistic rent assumptions are carrying more vacancy risk than they were 12 months ago.

The “Value-Add 4th Bedroom” Problem

Wholesalers frequently pitch bedroom conversion as a rent booster on lower-income urban core rentals. The logic is that more bedrooms equal higher rent. In practice, this rarely moves the needle in 46218 or similar zip codes.

Converting living space to a bedroom in a sub-$1,500 rent range property typically adds between $0 and $75 per month in achievable rent, while removing a feature, a living room or dining room, that families in this tenant pool actually want. You also add square footage to maintain, paint, and floor at every turn. Interior repaint in Indianapolis runs approximately $3,000 per unit in 2026. If the conversion adds a room, it adds to that cost at every future turn.

The value-add pitch sounds like upside. Run it through actual rent comps and it usually disappears.

What Cap Rate to Require in This Market

The half-the-rent rule produces a rough cap rate. Here is what that number needs to mean in practice for Indianapolis urban core buy-and-hold rentals.

A cap rate below 7% on this asset class means you are paying a price that does not compensate for the management intensity, tenant risk, and maintenance demands of lower-income urban core properties. You are accepting a return profile closer to stabilized suburban assets while taking on urban core operational complexity.

A cap rate between 7% and 8% is marginal. The deal might work if your actual operating expenses come in at the lower end of the range, if rent growth materializes, and if you have minimal deferred maintenance. There is no cushion for surprises.

A cap rate above 8% is where Indianapolis urban core deals have historically penciled for experienced buy-and-hold investors. It provides enough margin to absorb a bad turn, an unexpected repair, or a vacancy stretch without threatening cash flow for the year.

Debt service is separate from this calculation. The cap rate tells you whether the asset generates adequate return on its own. Whether that return survives your specific financing terms is the next question, and it is a harder one if you are starting from a marginal cap rate.

Why the 1% Rule Is Not Enough on Its Own

The 1% rule says that monthly rent should equal at least 1% of purchase price. On a $110,000 property, that means $1,100 per month minimum. On a $145,000 property, it means $1,450. The rule is useful as a first pass, but it has two significant weaknesses in the current Indianapolis market.

First, it does not account for the relationship between assessed value and taxes. Two properties at the same purchase price in different parts of Marion County can carry meaningfully different tax burdens depending on how assessed value tracks purchase price. In the urban core, assessed values sometimes lag purchase prices, which works in your favor. In other cases, a recent sale triggers reassessment toward market value, and the tax line in your underwriting changes materially.

Second, the 1% rule does not tell you anything about what is achievable at current market rents. A wholesaler quoting “$1,200 plus” on a 46218 property is not quoting you a number they have verified against recent lease comps. That number often represents what the property last rented for, what a nearby comparable rented for, or what they need the number to be for the deal to look attractive. The subject-to deal breakdown published here previously covers this problem in detail – a deal can technically clear the 1% rule and still produce negative cash flow from day one.

The half-the-rent rule combined with an 8% cap rate threshold gives you a more complete 90-second filter than the 1% rule alone.

The Quick Reference Table

Here is how the math plays out across common rent and price combinations in the Indianapolis market. NOI is calculated at 50% of gross rent. Cap rate is NOI divided by purchase price.

Monthly Rent	Annual Gross	50% NOI	Max Price at 8% Cap
$1,100	$13,200	$6,600	$82,500
$1,200	$14,400	$7,200	$90,000
$1,300	$15,600	$7,800	$97,500
$1,400	$16,800	$8,400	$105,000
$1,500	$18,000	$9,000	$112,500

The table makes one thing clear. At the rent levels typical for urban core Indianapolis zip codes 46201, 46218, 46219, 46222, and 46227, a property needs to be priced in the $82,500 to $112,500 range to clear an 8% cap rate. Wholesale listings in these same zip codes frequently come in $20,000 to $40,000 above those thresholds, with rent projections that require verification and value-add assumptions that rarely materialize.

What to Do With a Deal That Clears the Screen

The half-the-rent rule is a filter, not a finish line. If a listing clears 8%, it has earned a deeper look. That deeper look should include:

Actual lease comps within a quarter mile, pulled from MLS data, not the wholesaler’s estimate. Current assessed value from the county assessor’s website, not the purchase price as a proxy. An insurance quote specific to the property and zip code. A physical inspection or, if you are buying from out of state, an HD video walkthrough before committing. And a realistic repair reserve that accounts for the age and condition of the specific property, not a flat percentage applied to every deal in the portfolio.

For investors managing Indianapolis properties from out of state, getting those verification steps done without a trusted local resource on the ground is the single biggest gap between a deal that looks right on paper and one that performs as expected after closing. The investor closing checklist covers the full pre-close verification process in detail.

The Bottom Line

Wholesalers are not obligated to run your numbers for you. That is not an indictment of wholesalers. It is just the reality of how that part of the market works. The listing is designed to generate interest. Your job is to determine whether the interest is warranted.

The half-the-rent rule gives you a filter that takes 90 seconds and requires nothing more than the two numbers that appear in every wholesale listing: the rent and the price. If the result does not clear 8%, the deal does not deserve more of your time regardless of what the subject line says about the 1% rule, the projected cashflow, or the comps exploding.

The best deals you will do in Indianapolis real estate are often the ones you walked away from quickly, without spending three hours on due diligence for a property that was never going to pencil.
