How to Value a Property: Three Methods
Three ways to value a flat. Run all three — and pay close attention to where they disagree, because that gap is telling you something.
The short answer
Three methods:
1. COMPARABLE SALES — what similar flats actually sold for. The primary method.
2. RENTAL YIELD — what the income justifies.
3. REPLACEMENT COST — land + construction.
Run all three. Where they disagree is the most interesting thing you will learn.
Method 1 — Comparable sales (the primary one)
Find flats that actually sold — not listed, sold — that are genuinely comparable, and adjust.
| Factor | Adjustment |
|---|---|
| Carpet area | The obvious one. Compare per sq ft of CARPET, not super built-up — loading factors differ between projects and will mislead you. |
| Floor | Higher usually commands more. Ground and top floors often less. |
| Facing & view | Park-facing vs generator-facing is a real difference, and a large one. |
| Age & condition | A renovated flat vs one needing ₹8 lakh of work. |
| Parking | Covered? How many? This is worth real money. |
| When it sold | A transaction from 18 months ago in a moving market is stale. |
| Was it a distress sale? | Then it is not a fair comparable — it is evidence of a floor. |
Compare per square foot of CARPET area. Two projects quoting per square foot of super built-up, with loading factors of 25% and 40%, are quoting numbers that are not comparable at all — and that is precisely why they quote it that way.
Method 2 — Rental yield (the reality check)
What the income justifies
Value = Annual rent ÷ Expected yield
- Comparable flats rent for
- ₹28,000/month
- Annual rent
- ₹3,36,000
- Yields in this locality run at
- 3%
- Value on an income basis
- ₹1.12 crore
The seller is asking ₹1.4 crore. The rent supports ₹1.12 crore at the locality's normal yield.
That gap is not necessarily an error. It may reflect genuine expected appreciation — an arriving metro, a new business district.
But it may also reflect a price that has detached from what the asset earns.
The gap is the question. And you should be able to answer it before you pay it.
“Because prices always go up” is not an answer. “Because three IT campuses open within 4km next year” is.
Method 3 — Replacement cost (the floor)
What it would cost to build it again
- Land — your undivided share × the land rate
- Varies enormously
- Construction — carpet area × construction cost
- ₹2,000–₹3,500/sq ft, by quality
- Less: depreciation on the building, by age
- Real, and often ignored
- Replacement cost
- A rough floor
Useful mainly for land and plots, and as a sanity check on a new project. If a builder is charging far above replacement cost in a market with plenty of land, ask what you are paying for.
Where the methods disagree — this is the useful part
| The pattern | What it means |
|---|---|
| Comparables HIGH, yield LOW | The market is pricing in appreciation. Fine — if you can name the reason. Dangerous if you cannot. |
| Comparables LOW, yield HIGH | Possibly a genuine opportunity — or the locality has a problem you haven't found. Go and look for the problem. |
| Asking price far above ALL THREE | The seller is dreaming. Check how long the flat has been listed. If it's months, you have power. |
| Price below replacement cost | Something is wrong. Title. B khata. No OC. A structural problem. Find it before you congratulate yourself. |
1. Find three flats that sold in the building or the street. Get the per-sq-ft carpet rate.
2. Find three comparable flats for rent. Work out the yield.
3. Ask yourself whether the gap between the two is justified by something you can name.
That is an hour's work, it costs nothing, and it puts you ahead of almost every buyer in the market — most of whom will do none of it, and will instead spend three weekends choosing a floor plan.
Frequently asked questions
How do I value a property?
Three methods, and use all three. Comparable sales — what similar flats ACTUALLY sold for, compared per square foot of CARPET area. Rental yield — what the income justifies, being annual rent divided by the locality's normal yield. And replacement cost — land plus construction, less depreciation. Where they disagree is the most interesting thing you will learn.
Should I compare per square foot of carpet or super built-up?
Carpet, always. Two projects quoting per square foot of super built-up with loading factors of 25% and 40% are quoting numbers that are not comparable at all — and that is precisely why they quote it that way.
What does it mean if the rental yield doesn't support the price?
That the market is pricing in appreciation. That may be entirely justified — an arriving metro, a new business district. Or it may reflect a price that has detached from what the asset earns. The gap is the question, and you should be able to answer it before you pay it. 'Because prices always go up' is not an answer.
What if a property is priced below its replacement cost?
Something is wrong. Title, a B khata, no occupancy certificate, a structural problem, a legal dispute. Find it before you congratulate yourself on the bargain.
What is the quickest way to value a flat?
An hour's work. Find three flats that SOLD in the building or street and get the per-square-foot carpet rate. Find three comparable flats for rent and work out the yield. Then ask whether the gap between the two is justified by something you can actually name. It costs nothing and puts you ahead of almost every buyer in the market.
