Plot Loan vs Home Loan vs Construction Loan
A buyer in Sohna picks up a 200 sq yd plot for Rs 90 lakh, borrows Rs 60 lakh against it, and files his return in July expecting the usual Rs 2 lakh interest deduction. He does not get it, and he will not get it next year either, unless he builds a house on that plot and moves in.
That is the most expensive misunderstanding in plot financing, and it sits alongside lower funding, shorter tenure, a higher rate, and a construction deadline most borrowers never read.
Key takeaways
- A plot loan funds 60% to 75% of land value against 75% to 90% on a home loan, so you bring 25% to 40% of the cost yourself.
- Plot loan tenure is capped at 10 to 15 years, against up to 30 years on a home loan, which lifts the EMI by more than a third on the same amount.
- Plot loans price 25 to 100 basis points above home loans at the same lender and credit score.
- No Section 24(b) or Section 80C deduction on a plot loan until the house is built and you own a house property. A composite loan converts into one once construction ends.
- Lenders give you 2 to 3 years to start construction and 3 to 5 to finish, and the tax law runs its own separate 5-year clock.
Three products, not one
Banks lump these under "housing finance" but they behave differently at every step. A plot loan (some lenders call it a land or realty loan) funds a residential plot with no commitment to build. A home loan funds a built house or flat. A composite loan, marketed as plot-plus-construction, funds both in one sanction: the land portion goes out first, the construction portion follows in tranches.
| Plot loan | Composite loan | Home loan | |
|---|---|---|---|
| Loan to value | 60% to 75% | 75% to 80% of combined cost | 90% up to Rs 30 lakh, 80% to Rs 75 lakh, 75% above |
| Maximum tenure | 10 to 15 years | 20 to 30 years | Up to 30 years |
| Rate versus home loan | +25 to +100 bps | Same as home loan, or +10 bps | Benchmark |
| Section 24(b) interest | None | After completion and possession | Up to Rs 2 lakh, old regime |
| Section 80C principal | None | After completion | Within the Rs 1.5 lakh cap |
| Disbursement | Single, on registration | Land first, then 3 to 5 slabs | Single or construction-linked |
| Property allowed | Approved layout, municipal or development authority limits | Same, plus approved building plan | Any legally saleable house or flat |
| PMAY subsidy | Not available | Available on the construction component | Available if eligible |
What that does to the EMI
Take the same Rs 60 lakh. A home loan at 7.75% over 20 years is an EMI of about Rs 49,250. A plot loan at 8.75% over 12 years is about Rs 67,450. Same principal, Rs 18,180 a month more, and a borrower whose income supports the first often fails the FOIR test on the second. That gap, not the rate, is why many plot purchases end up part-funded by a personal loan or family money.
The tax trap in detail
Section 24(b) of the Income-tax Act allows a deduction for interest on capital borrowed for the acquisition, construction, repair or reconstruction of house property. A vacant plot is not house property. So while the land sits empty, the interest is not deductible at all — not as a loss from house property, not against salary, not anywhere. Section 80C on principal repayment is equally unavailable, because it applies to the purchase or construction of a residential house.
Once the house is built and you take possession, three things happen:
- Interest from that year onward becomes deductible, up to Rs 2 lakh a year for a self-occupied house under the old regime, with no cap for a let-out one (though the set-off against other income is limited to Rs 2 lakh).
- Pre-construction interest — everything paid from the date of borrowing to the 31 March before the year of completion — becomes claimable in five equal annual instalments, starting the year construction is completed. It sits inside the same Rs 2 lakh ceiling for a self-occupied house, so on a large loan most of it is simply lost.
- Principal repaid after completion qualifies under Section 80C, subject to the Rs 1.5 lakh combined cap.
There is a deadline. For the Rs 2 lakh self-occupied limit to apply, the acquisition or construction must be completed within five years from the end of the financial year in which the loan was taken. Miss it and the deduction collapses to Rs 30,000 a year. The same Rs 30,000 cap applies to a loan taken for repair or reconstruction.
The part most articles miss
Under the new tax regime of Section 115BAC, which is now the default, the Section 24(b) deduction on a self-occupied house is not available at all, and Section 80C does not exist. Interest on a let-out property remains deductible, but the resulting loss cannot be set off against salary.
So if you are on the new regime and building a house to live in, the tax difference between a plot loan and a home loan is close to zero — because neither gives you anything. The plot loan's real penalties are the LTV, the tenure and the rate. Work out which regime you will be on before you let a lender sell you a composite loan on the tax argument.
How a composite loan is actually released
The land portion goes out on registration of the sale deed, usually 60% to 70% of the plot cost. The construction portion is released against progress, certified by the lender's empanelled valuer or engineer at each stage:
- Foundation and plinth — around 20% of the construction sanction.
- Ground floor slab or first-floor roof — 25%.
- Brickwork and superstructure — 20%.
- Plastering, flooring and electricals — 20%.
- Final finishing and handover — 15%.
You pay only interest on the amount drawn until the last tranche, then the full EMI begins. Two traps. The lender releases against work done, not work planned, so you fund each stage before reimbursement. And the construction estimate sanctioned is the one their valuer accepts, not your contractor's quote, which is usually lower.
The clock on starting construction
Every plot and composite loan carries a construction condition, and it is enforceable. Most lenders require construction to begin within 2 to 3 years of the first disbursement and to be finished within 3 to 5. The exact deadline is a term of your sanction letter, not an industry standard. If you miss it, the lender can reprice the loan to a commercial rate, shorten the tenure, or recall it. In practice they usually reprice. If your plan is genuinely to hold land for appreciation, a plot loan is the wrong instrument and you should be looking at a loan against another property instead — the comparison of loan against property and home loans sets out where that lands.
What lenders will and will not fund
- Yes: a residential plot in a municipal or development authority approved layout, within corporation or municipal limits, with a clean title and a plan-sanctionable status. Licensed colonies in Haryana, DDA and authority plots, and approved private layouts all qualify — for example, licensed plotted colonies of the DDJAY type or approved Sohna plot inventory.
- No: agricultural land, land under a change-of-land-use application that has not yet been granted, unapproved colonies, and plots on Lal Dora land in Delhi, which most banks decline outright because the title chain does not survive their legal check.
- Case by case: plots in gram panchayat areas, plots with an unresolved change-of-land-use status, and resale plots where the layout approval predates the current municipal boundary.
SBI, HDFC Bank, LIC Housing Finance, PNB Housing, ICICI Bank and Bajaj Housing all run plot and composite products on broadly similar terms; some NBFCs go higher on LTV and charge for it. Rates move with the repo, held at 5.25%, so compare the spread over the benchmark rather than the headline. Home loan floors at the large banks sit in the 7.10% to 7.50% band and run to about 8.45% depending on credit score and loan size, with the plot loan priced above that.
Which one to take
If you will build within two years, take the composite loan. It gives you the home loan tenure and rate, one set of processing fees and one legal opinion, and converts into a tax-deductible home loan the day you take possession. Buying land to hold, take the plot loan with your eyes open on the construction clause, and size the EMI on a 12-year tenure rather than the 20 you had in mind. Either way, budget the down payment first — how much you actually need upfront is a larger number on a plot than on a flat.
FAQ
Can I claim tax benefit on a plot loan?
Not while the plot is vacant. Neither Section 24(b) nor Section 80C applies to a bare plot. Once you build and take possession, interest becomes deductible and the pre-construction interest can be claimed in five equal instalments, within the applicable cap.
How much loan can I get to buy a plot?
Usually 60% to 75% of the land value as assessed by the lender's valuer, which can be below the price you paid. On a Rs 90 lakh plot expect a sanction of Rs 54 lakh to Rs 67 lakh, and be ready to fund the gap plus stamp duty from your own resources.
Is a plot loan rate higher than a home loan rate?
Yes, typically 25 to 100 basis points higher at the same lender for the same credit profile, because the security is unbuilt land and the recovery value in a default is less predictable.
What if I do not build within the time limit?
The lender can reprice the loan to a commercial or non-housing rate, reduce the tenure, or in the extreme recall it. Ask for the exact clause and deadline before you sign, because the sanction letter and the marketing brochure often differ.
Can I convert a plot loan into a home loan later?
Some lenders allow it once you have a sanctioned building plan and start construction, effectively restructuring it into a composite loan with a longer tenure. It is not automatic and it is not universal — if you know you will build, take the composite loan at the outset.
