Carpet area used for home loan and loan against property valuation

Carpet Area in Loan Against Property and Home Loan Valuation

Dasadia Editorial Team · Updated August 2026

The valuer spends about forty minutes in the flat with a laser measure and a clipboard. He works room by room, checks the layout against the sanctioned plan, photographs the building and leaves. The number he writes in his report isn’t the number in the brochure, and it is the only one your bank will lend against.

Most buyers never read that report. They paid for it.

Carpet area sits at the centre of this because it is the one measurement every serious party agrees on. RERA requires builders to price and contract on it. MahaRERA publishes it for every registered project. The bank’s empanelled valuer measures it. The stamp duty reckoner is derived from it. The saleable area printed on the brochure appears in none of those places, which is why budgeting from it is the most dependable way to end up short at disbursal. This guide covers what the valuer measures, how that measurement reaches your sanctioned amount, why a loan against property tightens every one of those steps, and the conversion rule Maharashtra applies before a rupee of stamp duty is calculated.

Key takeaways

Three areas, three different numbers, one flat

Three measurements govern three different numbers on the same property, and confusing them is where the money leaks. The figures below assume a flat marketed as 950 square feet with a 35% loading factor, which is ordinary for Mumbai.

Notice which row the bank sits in. Your lender’s valuer works from carpet and built-up area, the same basis the sub-registrar uses. The saleable figure exists for marketing and for splitting the maintenance bill, and you won’t find it in a valuation report anywhere.

A rate that looks cheap across 950 square feet isn’t cheap. It is the same money spread over a bigger number.

What the bank's valuer actually measures

The technical appraisal is a physical inspection, not a desk exercise. The valuer measures carpet and built-up area and checks both against the approved plan. He assesses construction quality, looking for cracks, moisture and structural weakness. He records whether the flat is vacant, self-occupied or let. And he looks for deviations from the sanctioned layout. An enclosed balcony, a merged flat or an unapproved additional floor can each be deducted from the valuation or sink the application outright. Legal verification runs alongside and usually takes three to seven working days, longer if old title deeds have to be retrieved.

Banks appoint their own empanelled valuers and charge you for the exercise. For regulatory purposes the valuer must be registered with the IBBI. The report is normally valid for six to twelve months, so a stale report on a resale deal gets redone.

Ask for a copy of the valuation report before you sign anything. You paid for it, and it is the only independent measurement of that flat you’ll ever be handed. Our experience is that lenders release it on request and rarely offer it unprompted.

How the measurement reaches your sanctioned amount

Loan to value caps are set by the RBI, and they apply to the lower of the assessed value and the agreement value.

Loan amount
Maximum LTV
Your contribution
Up to ₹30 lakh
90%
10% or more
Above ₹30 lakh to ₹75 lakh
80%
20% or more
Above ₹75 lakh
75%
25% or more
Loan against property
Commonly up to 75%, lower at many lenders
25% or more

That word ‘lower’ is doing all the work. If the valuer comes in under your agreement value, the difference lands on you in cash, not on the seller and not on the bank.

A 5% valuation gap adds ₹7.5 lakh to the down payment on a ₹2 crore flat. Nothing about the flat changed. The bank only declined to lend against a number it hadn’t measured.

Two things reduce that risk, and neither costs anything. Ask your lender for an indicative valuation before you pay a large token amount, which most will give you informally on a building they already have exposure to. And if the report does come in low, use it rather than hide it. A written assessment from a registered valuer is the strongest negotiating document a buyer ever holds, and a seller who won’t move on the number will meet a similar one at the next bank, because the comparable sales feeding these reports are the same across lenders.

Stamp duty and registration sit outside the LTV base on loans of this size, so budget them separately. In Mumbai that means 6% for male buyers and 5% for female buyers, both including the metro cess, plus 1% registration capped at ₹30,000.

Why carpet area matters more in a loan against property

Loan against property tightens every point above. The LTV ceiling is commonly around 75% and several lenders sit well below it, so each rupee of assessed value carries more weight. Valuers approach a mortgaged property more conservatively than a purchase, because the lender is thinking about what the asset would fetch if it ever had to be sold rather than what a willing buyer would pay today. And the older the building, the more depreciation gets applied to the construction component of the valuation, which is why a forty-year-old flat in a good pocket doesn’t raise anything close to what its resale price suggests.

The carpet area problem is sharper here because the flat is usually old. Agreements executed before 2017 often state built-up or saleable area alone, and some state neither with any accuracy. Where the document carries no reliable carpet figure, the valuer measures on site and that measurement governs, which is how owners find out their flat is smaller than they had assumed for twenty years.

Get the carpet area measured before you apply, not after.

The 1.2 rule that converts your carpet area for stamp duty

We went to the Maharashtra reckoner guideline directly on this, because it is widely misquoted. The rates published in the stamp duty ready reckoner are for built-up area, quoted per square metre. Where your document states carpet area, the built-up figure is taken as the higher of the actual built-up area recorded and 1.2 times the carpet area. On a 704 square foot carpet flat that gives 845 square feet, or about 78.5 square metres at the standard conversion of 10.764 square feet to the square metre.

Neither the reckoner nor your bank has any use for the saleable number. It appears nowhere in the chain.

This reaches your loan because the bank cross-checks the agreement value against the reckoner value, and stamp duty is charged on whichever is higher. Across most Mumbai suburbs the agreement value wins comfortably, since asking rates run well above reckoner rates. Where they don’t, you pay duty on a value higher than your price.

Frequently asked questions

Both, measured on site. The valuer records carpet area and built-up area and checks them against the sanctioned plan. Lenders including SBI and HDFC Bank work from the RERA carpet area definition in their valuation reports. Saleable or super built-up area is not used.

The most common reason is that LTV applies to the lower of the assessed value and the agreement value. If the valuer assesses the flat below your purchase price, your loan is calculated on the lower figure and the gap becomes additional down payment.

90% for loans up to ₹30 lakh, 80% for loans above ₹30 lakh and up to ₹75 lakh, and 75% for loans above ₹75 lakh, as capped by the RBI.

Commonly up to about 75% of assessed value, though many lenders operate well below that. LAP valuations also tend to be more conservative than purchase valuations, because the lender is assessing recoverability.

Indirectly, yes. A larger carpet area supports a higher assessed value, and the loan is a percentage of that value. But the valuer’s rate per square foot for the locality matters just as much as the area itself.

On the MahaRERA portal for any registered project, and in the sale agreement, which must state carpet area under RERA. For older flats you may need the architectural plan or an independent measurement.

Built-up area. In Maharashtra the built-up figure is taken as the higher of the actual built-up area in the documents and 1.2 times the carpet area, and reckoner rates are quoted per square metre.

Multiply carpet area by 1.2, then compare against any actual built-up area stated in the documents and use the higher of the two. To convert square feet to square metres, divide by 10.764.

It can reject or reduce the loan if the measured area does not match the approved plan, or if there are unauthorised alterations such as an enclosed balcony, a merged flat or an unapproved additional floor. Those areas may be deducted from the valuation.

You do. The bank appoints a valuer from its own panel and passes the cost to the borrower. Since you are paying, ask for a copy of the report.

Typically six to twelve months from the date of issue. Beyond that most lenders require a fresh valuation, particularly on resale transactions.

On loans of this size they generally sit outside the value used to compute LTV, so plan for them in cash. In Mumbai budget 6% stamp duty for male buyers or 5% for female buyers including the metro cess, plus 1% registration capped at ₹30,000.

RERA permits a deviation of up to 3%. Beyond that the promoter must refund the excess amount paid, with interest, and the timeline for that is set out in the sale agreement.

Not as a standalone figure, but you can derive it. Compare the RERA carpet area on the MahaRERA registration with the saleable area the builder quotes. Ask for the loading factor in writing before you book.

It is the strongest negotiating document a buyer holds. An independent registered valuer has put a number on the property in writing, and a seller who refuses to move will encounter a similar figure at the next lender.

LTV ceilings, interest rates, stamp duty percentages and reckoner rules are stated as they applied during 2026 and can change by RBI direction or state notification. Individual lenders apply their own credit policies within the regulatory caps, so the amount any particular bank sanctions may differ from the arithmetic shown here. The worked example is an illustration built on assumed figures, not a quotation.
