What is margin money?
When you take a home loan to build a house, the bank lends only a part of the total cost. The rest has to come from your own savings. This share is called your own contribution or margin money.
Many families in Bangalore plan their construction budget around the loan amount alone and are surprised when the bank asks them to show their own contribution first. Knowing the numbers in advance helps you fix the right size of home, the right package and a realistic timeline.
If you are new to construction loans, read our home construction loan guide first, then come back to this article.
RBI loan-to-value (LTV) limits
The Reserve Bank of India caps how much banks and housing finance companies can lend against the value of a home. This cap is called the loan-to-value or LTV ratio. The commonly applied limits are:
- Loans up to ₹30 lakh: up to 90 percent of the property value
- Loans above ₹30 lakh and up to ₹75 lakh: up to 80 percent
- Loans above ₹75 lakh: up to 75 percent
These are upper limits. Your lender may offer less depending on your income, credit score, age, existing loans and its own valuation of the plot and the planned building. Always confirm the current rules and the bank's own policy with your lender before you sign a construction agreement.
Worked examples
Here is how the limits play out for typical Bangalore projects. The examples use construction cost only, assuming you already own the plot.
Example 1: G+1 home costing ₹40 lakh. A loan of ₹32 lakh at 80 percent falls in the ₹30 to ₹75 lakh band, so the bank can lend up to 80 percent. Your own contribution is at least ₹8 lakh.
Example 2: G+2 home costing ₹60 lakh. At 80 percent, the maximum loan is ₹48 lakh and your own contribution is at least ₹12 lakh.
Example 3: G+3 home costing ₹1 crore. A loan above ₹75 lakh is capped at 75 percent, so the maximum loan is ₹75 lakh and you need at least ₹25 lakh of your own money.

Costs the loan usually does not cover
Apart from the margin on construction, plan your own funds for costs that lenders usually do not finance. Common examples are:
- Loan processing fees, legal and technical verification charges
- Stamp duty and registration on the loan or construction agreement, where applicable
- Government fees for plan sanction, and BESCOM and BWSSB connection charges
- Furniture, loose fittings and items outside your construction package
- A contingency for changes you make during construction
Our article on the hidden costs of house construction explains each of these in more detail.
When your own money is needed
A construction loan is not paid out in one go. The bank releases it in instalments as the work progresses, usually after its engineer inspects the site. Most banks expect your own contribution to be used first, or in proportion, before they release their share. Read our guide to construction loan disbursement stages to see how this works.
At Golden Homes, you pay 5 percent on agreement day. After that, payments are stage-wise, linked to completed construction stages and your fixed final quotation. This fits naturally with how banks disburse loans: your 5 percent and early stages come from your own funds, and later stages are paid as the bank releases each instalment. You can see our process on the How We Work page.
How to plan your own contribution
- Get an estimate first. Use our cost estimator to see the approximate cost for your built-up area and package.
- Check your loan eligibility early. Ask two or three lenders for an in-principle sanction based on your income, before you finalise the design.
- Keep the margin in a liquid form. Fixed deposits that can be broken without heavy penalties, or a savings account, work better than funds locked in for years.
- Consider a co-applicant. Adding an earning spouse or parent can raise your eligibility. Speak to your lender about the rules.
- Keep a buffer. Hold back at least 5 percent of the construction cost for changes and extras.
If your own contribution is tight, you can reduce the built-up area, choose a different package or build in phases, with the structure designed for future floors. Our EMI and budget guide helps you find the right balance.
Common mistakes to avoid
- Planning the house around the maximum loan. The loan you are eligible for and the EMI you can comfortably pay are not the same thing. Fix the EMI first, then the loan, then the size of the home.
- Spending the margin on the plot or interiors. If your savings go into other costs before construction starts, the bank may pause disbursement until you show your share.
- Forgetting the time gap. Bank inspections and paperwork take time. Keep a small buffer so work on site does not stop while an instalment is being processed.
- Changing the scope mid-way. Additions after the loan is sanctioned are usually funded entirely from your pocket, so freeze the design before you apply.
- Ignoring interest during construction. Many banks charge interest on the amount disbursed while the house is being built. Include this pre-EMI interest in your monthly budget.
A clear plan for your own contribution, a fixed quotation and stage-wise payments together keep your project on track from the first payment to handover.
If you are buying the plot too
If you are buying a plot and building on it, a combined plot plus construction loan has its own rules on how much of the plot cost the bank will fund and how soon construction must start. Read our guide to the plot plus construction loan before you commit to a plot, and check the documents carefully with our plot document checklist.

Frequently asked questions
How much of my own money do I need to build a house with a home loan?
It depends on the loan size. Under RBI limits, banks can lend up to 90 percent for loans up to ₹30 lakh, up to 80 percent for loans between ₹30 lakh and ₹75 lakh, and up to 75 percent above ₹75 lakh. You fund the rest, plus fees and extras.
Do banks release the construction loan before I pay my share?
Usually not. Most banks expect your own contribution to go in first or in proportion, and then release their instalments stage by stage after inspection.
Can a co-applicant increase my loan amount?
Often yes. Adding an earning co-applicant can raise your loan eligibility, but the LTV limit on the property still applies.
