Why a $1.8M District 15 Condo at $5,200 Rent Nets Just 2.42% — Not the 4% Everyone Quotes

Run the actual math on a realistic District 15 resale condo — $1,800,000 purchase price, $5,200 a month in rent, real maintenance, real property tax — and net yield lands at 2.42%. Not the 3.5-4% figure that gets thrown around in a listing description. That gap isn't rounding error; it's four specific deductions most buyers never subtract. We've covered why gross yield misleads buyers in the first place — this piece is the actual formula, line by line, so you can run it yourself on any listing in under two minutes.

The Exact Formula QuantField Runs

Every listing that reaches the daily screen gets the same calculation, no exceptions:

Net Yield = (Monthly Rent × 12 × 0.92 − Annual Maintenance − Annual Property Tax) / Purchase Price

Three things to notice before the worked example:

• The 0.92 multiplier is not a vacancy guess bolted on for pessimism — it's a combined haircut for realistic vacancy (roughly 3-4 weeks a year between tenants in a normal market) and the letting agent's commission (typically half a month's rent per 12-24 month lease, sometimes a full month on shorter or harder-to-lease units). Both are real, recurring costs. Skipping either one is the single most common way a self-calculated yield comes in high.
• Maintenance and property tax are subtracted in dollars, not as a percentage — they don't scale with rent, so on a lower-rent unit they eat a proportionally bigger chunk of yield.
• The denominator is purchase price, not valuation or asking price minus discount — net yield answers "what do I actually earn on the capital I'm putting in," so it has to use the number you're actually paying.

This is the same formula behind the QuantField Score methodology, where Yield Strength is 40 of the 100 possible points — and even a listing that clears the buy-box on net yield doesn't automatically score high, because yield is only one of five components.

Step 1: Get a Real Rent Number, Not an Asking-Rent Guess

The single biggest lever in this formula is the rent assumption, and it's the one buyers get wrong most confidently.

There are two ways to arrive at a monthly rent figure:

1. URA private residential rental transaction data — actual signed leases, by project or by district, updated quarterly. This tells you what tenants are actually paying for comparable units right now, not what a landlord hopes to get.
2. A hardcoded estimate — a rule-of-thumb PSF-per-month figure, or worse, the asking rent from a competing listing that hasn't found a tenant yet.

These produce meaningfully different numbers. Asking rents are anchored to what a landlord wants; transacted rents are anchored to what the market clears at. In a softening rental market, the gap between the two can run 5-10%, and it compounds directly into the yield figure because rent is multiplied by 12 before anything else happens.

This is exactly why Data Confidence is one of QuantField's five score components (0-10 points) — it explicitly rewards listings where rent is pulled from live URA transaction data over a hardcoded estimate. A 4.5% "yield" built on an optimistic asking rent and a 4.5% yield built on actual signed leases are not the same claim, even though they look identical on a listing page. Full breakdown of how that scoring works is in how QuantField's screen operates.

For the worked example below, $5,200/month reflects realistic transacted rent for a ~980 sqft 2-bedroom in District 15 — not the $5,700-5,800 an optimistic asking-rent line might show.

Step 2: Subtract What Actually Leaves Your Pocket — Maintenance

Condo maintenance (MCST fees) is the deduction almost nobody forgets entirely, but plenty of buyers underestimate it by using the current fee instead of budgeting for the fact that it only moves one direction — up.

For a District 15 development of this size, $350/month ($4,200/year) is a reasonable current figure. It doesn't fluctuate with rent, so on a lower-yielding unit it represents a bigger proportional drag — another reason a $1,200/month studio and a $5,200/month 2-bedroom don't scale the same way when you're comparing "yield" across unit types.

Step 3: Estimate Non-Owner-Occupied Property Tax Correctly

This is the deduction most self-calculated yields skip entirely, and it's the largest one in the formula after rent.

Singapore property tax for a non-owner-occupied residential unit is charged on the property's Annual Value (AV) — broadly, the estimated annual market rent — using IRAS's progressive non-owner-occupied schedule, where the tax rate rises in bands as AV increases. It is meaningfully higher than the owner-occupier schedule, because non-owner-occupied is treated as an investment asset, not a home.

For a unit with an AV around $56,000 (roughly in line with $5,200/month in market rent), the progressive bands work out to an effective annual property tax in the region of $9,500-$9,800 — not a flat percentage, and not the same figure an owner-occupier would pay on an identical unit next door. This is the deduction that most inflates a buyer's mental yield calculation when it's left out, because it's easy to forget it exists at all if you've only ever owned your own home.

The Full Worked Example

Putting it together for the $1,800,000 District 15 unit at $5,200/month:

Compare that to QuantField's buy-box floor of 3.2% net yield, detailed on the buy-box criteria page — this exact, realistic District 15 unit doesn't clear it. That's not a contrived example designed to fail; it's what a large share of District 15 resale stock actually looks like once the real deductions are applied, which is precisely why on most days only a small fraction of new District 15 listings make it through the daily screen at all.

Contrast that with the listing from yesterday's screen that cleared at 4.19% net yield and still only scored 64/100 — the yield component alone doesn't guarantee a strong score, but it does have to clear the floor first. The 2.42% unit above never gets that far.

Where Buyers Get This Wrong

Four mistakes account for almost every inflated self-calculated yield we see:

1. Using asking rent instead of achievable rent. Anchoring to the highest comparable listing on a portal, not what units are actually leasing at.
2. Forgetting vacancy entirely. Assuming the unit is tenanted 12 months a year, every year, with zero gap between leases.
3. Forgetting agent's letting commission. A recurring cost every time the unit is re-let, not a one-off.
4. Skipping property tax because they've never paid the non-owner-occupied schedule. The largest silent deduction in the entire formula, and the easiest one to leave out if you've only budgeted for maintenance.

Any one of these alone can push a 2.4% unit to look like a 3.5% unit on paper. Stack two or three together and a genuinely sub-floor property reads as a buy-box pass.

What This Means For You

Buyers: Run this exact formula — not the agent's headline number — before treating any advertised yield as real. If you can't get a realistic rent comp from URA data for the specific project or a close comparable, treat any yield claim on that listing as unverified.

Sellers/agents: Listings marketed on gross yield invite exactly this kind of correction once a serious buyer runs their own numbers. Leading with a net figure, deductions shown, is a credibility signal — not a weaker pitch.

Anyone evaluating a specific unit: you can run this exact screen against your own listing rather than doing the arithmetic by hand — it applies the same rent, maintenance, and property tax logic shown above automatically.
