A plot loan carries one condition a home loan does not: RBI's Master Circular on Housing Finance lets a bank fund land only against your declaration that you intend to build on it, within a deadline the bank sets. Beyond that, a floating-rate plot loan has no prepayment penalty, its rate tracks the repo rate through the same external-benchmark rule as a home loan, and the interest deduction under Section 24(b) starts only once construction is complete — not from the date the plot loan is disbursed.
The RBI rule that makes a plot loan a plot loan
RBI does not set plot-loan tenure or funding percentages — those are bank policy, which is why the tenure and LTV figures above are sourced to HDFC's and SBI's own product pages rather than to RBI. What RBI's Master Circular – Housing Finance (February 2022) does set is the eligibility condition itself: a bank "can be granted only for purchase of a plot, provided a declaration is obtained from the borrower that he intends to construct a house on the said plot", with construction to be completed within whatever period the bank fixes. A land purchase with no declared construction intent is not something a bank can fund as a plot loan under this circular — that is why every lender's application form asks for a construction undertaking, separate from the valuation report.
The same circular sets a rule that matters once the plot loan converts into a construction loan: banks must exclude stamp duty, registration and documentation charges from the property cost used to compute LTV, with one exception — where the cost of the house does not exceed ₹10 lakh, a bank may add stamp duty, registration and documentation charges into the cost for the LTV calculation. On a plot-plus-construction package that stays under that ₹10 lakh line, the stamp duty on the land registration can be folded into what the LTV is measured against; above it, you fund stamp duty and registration entirely yourself, on top of the loan.
No prepayment penalty if the loan is floating-rate
RBI's Pre-payment Charges on Loans Directions, 2025 bar lenders from levying pre-payment or foreclosure charges on floating-rate loans sanctioned to individuals for purposes other than business, regardless of the funding source used to prepay or any lock-in period. A plot loan taken by a salaried or self-employed individual to build a personal residence is squarely a non-business loan, so a floating-rate plot loan qualifies: "For all loans granted for purposes other than business to individuals, with or without co-obligant(s), an RE shall not levy pre-payment charges". The Directions apply to loans sanctioned or renewed on or after 1 January 2026 — check your sanction letter's date before assuming it applies, and note a fixed-rate plot loan is not covered by this rule.
Why a floating plot-loan rate tracks the repo rate
Since 1 October 2019, RBI has required that "all new floating rate personal or retail loans and floating rate loans to MSMEs" be linked to an external benchmark — commonly the repo rate — with the lender free to set its own spread over that benchmark, changeable only on a genuine change in the borrower's creditworthiness. A floating-rate plot loan is a retail loan to an individual, so it falls under this external-benchmark mandate the same way a home loan does: when the repo rate moves, your EMI or tenure moves with it, on a schedule the lender sets (commonly quarterly), not on the lender's own discretion.
Section 24(b) does not start on the day the plot loan is disbursed
Under the old tax regime, interest on a housing loan for a self-occupied property is deductible up to ₹2,00,000 under Section 24(b), but a plot-only loan does not qualify for this deduction while the plot is undeveloped — the deduction attaches to a housing loan for a house, not to land. Once construction is complete and the house exists, interest paid during the construction period becomes deductible in five equal instalments starting from the year construction finishes, subject to the same ₹2,00,000 overall cap. The Income Tax Department's own FAQ on the new versus old regime confirms this deduction is old-regime-specific: "'Interest on borrowed capital for Self-occupied property' is not allowed as a deduction from Income from House property as per the provision of Section 115BAC" — so under the new (default) regime, none of this interest is deductible at all, whether the loan is a plot loan or a home loan.
Methodology
Every figure above is either quoted directly from the cited RBI or Income Tax Department source, or is arithmetic shown step by step from those figures in the worked example — no plot-loan LTV percentage, tenure figure or interest rate is asserted here beyond what the calculator above already sources to named lenders' own product pages.
