Understanding How the Mortgage Process Works

Buying a home is a major milestone. Most buyers rely on a mortgage, and the path from first enquiry to getting the keys involves legal, regulatory and practical steps. Early advice from a solicitor helps align these steps and prevents costly delays.

This guide explains the mortgage process in plain English. We’ll cover Central Bank rules such as Loan-to-Income and Loan-to-Value, the documents that lenders will expect, the valuation and survey, the loan offer, contracts, required insurances, drawdown, and post-completion registration.

Our aim here is to give you clear, actionable information so you can make informed decisions with confidence.

The rules at a glance

Before looking at properties, it helps to understand the rules that shape every mortgage application. These measures determine how much you can borrow, the deposit required, and how lenders assess affordability. Knowing them at the outset lets you set a realistic budget and plan your timeline with confidence.

• Loan-to-Income (LTI) – Most first-time buyers can borrow up to four times their gross income. Second and subsequent buyers are usually capped at three and a half times gross income. Lenders have limited scope to go above these limits for a minority of cases.
• Loan-to-Value (LTV) and deposit – A minimum deposit of ten per cent applies to both first-time and mover buyers (i.e. second-time buyers seeking to purchase a new home while selling their current one). Buy-to-let loans typically require a thirty per cent deposit.
• Allowances – Lenders can make exceptions within set quotas each year. The current framework allows a proportion of lending to exceed the standard LTI or LTV caps for first-time buyers, movers and buy-to-let borrowers.
• Fresh start status – If you previously owned a home but no longer have any interest in it because of separation, divorce, bankruptcy or insolvency, you may be treated as a first-time buyer for the mortgage measures. Certain top-ups and remortgages can also retain first-time buyer status where the property remains your home.
• Affordability and disclosures – Lenders must check that repayments are sustainable and provide a clear ESIS (European Standardised Information Sheet) before you commit. You should expect your lender to consider how rate rises could affect repayments.
• Insurance requirements – Mortgage protection life cover is a legal requirement for most home loans, with limited exemptions. Buildings insurance is required before drawdown.

The mortgage journey: step by step

With the key rules in mind, here is how a mortgage progresses from preparation to completion.

1. Get mortgage-ready

Tidy your accounts and limit new borrowing. Build a clear picture of income and regular spending. Gather core documents such as photo ID, PPSN, proof of address, payslips, bank statements, a salary certificate, and evidence of your deposit and any gifted funds. If you pay rent, keep a clean record of payments. Instruct a solicitor early so title, planning and timeline issues can be flagged in good time.

2. Apply for Approval in Principle

Submit an application with your documents so the lender can assess affordability and credit history. Approval in Principle gives you a budget and helps you move quickly when you find a property. It is not a binding offer, and it can expire, so note the validity date and keep your paperwork current.

3. House hunt and make an offer

View properties within your budget and make offers through the selling agent. When an offer is accepted, you will be asked for a booking deposit. This is usually refundable until contracts are signed. Ask for written confirmation of the terms. Share the agent’s details with your solicitor without delay.

4. Valuation and survey

Your lender will require a valuation by a panel valuer to confirm the property’s market value and condition for lending purposes. Arrange your own structural survey as well. A private survey looks beyond value and checks for issues that could affect safety, insurance or resale. It is a small cost that can prevent larger problems later.

5. Receive and review the loan offer

Once the lender completes underwriting, you will receive a formal loan offer with conditions and an ESIS. Read these with your solicitor. Pay close attention to special conditions, the interest rate and period, any requirements about life cover or home insurance, and any timelines for drawdown.

6. Contracts and deposit top-up

Your solicitor will review the contract, investigate the title, and raise pre-contract enquiries. When you are ready to proceed, you will sign the contract and increase the deposit so that the total deposit equals ten per cent unless otherwise agreed. The vendor will sign in turn. When both parties have signed, you are legally bound to complete.

7. Insurance and final lender conditions

Put mortgage protection life cover in place unless an exemption applies. Arrange buildings insurance that starts on completion. Make sure all lender conditions are satisfied, for example, a valuation that is still in date, up-to-date payslips, and any confirmations requested by the underwriter.

8. Drawdown and completion

Your solicitor will carry out final searches and provide undertakings to the lender. The lender will release funds to your solicitor. The balance of purchase money, stamp duty and agreed outlays are paid. Keys are released and you take possession on the completion date.

9. Post-completion and registration

Your solicitor will register your ownership and the lender’s charge with the Land Registry. Keep your title documents and insurance schedules safe. Set reminders for fixed-rate end dates and review your mortgage periodically to check whether a switch or product change could reduce your total cost.

State supports and schemes

If you are struggling to meet the criteria for a mortgage, there are numerous schemes available to help you get on the ladder. This includes:

Help to Buy (HTB)

A tax refund of up to €30,000 or ten per cent of the price or build cost, whichever is lower. Available to first-time buyers of new homes and self-builds. The enhanced relief runs to 31 December 2029. You can apply via the Revenue website.

First Home Scheme (FHS)

A shared equity top-up that can bridge the gap between your deposit plus mortgage and the purchase price or build cost. Up to 30%, or 20% if used with HTB. The scheme can be used for new builds and eligible self-builds, but it cannot be combined with the Local Authority Home Loan or the Local Authority Affordable Purchase Scheme.

Local Authority Home Loan (LAHL)

A Government-backed mortgage for eligible first-time and fresh-start buyers who cannot get sufficient finance from banks. It can be used for new or second-hand homes and for self-builds. Income limits are €70,000 for a single applicant and €85,000 for joint applicants.

Local Authority Affordable Purchase Scheme

New homes sold at a reduced price by local authorities. The council takes an equity share equal to the discount, and you can redeem that share later. Local income and price criteria apply to each development.

Self-builds and special situations

Self-build mortgages release funds in stages as the work progresses. An architect or engineer certifies each stage so the lender can draw down the next tranche. You usually pay interest only on the amount drawn. Keep a realistic budget with a contingency, and make sure planning permission, site access and services are in order before you start.

Your lender will look for costings, plans and professional appointments. Expect repeat valuations and inspections at each stage. Put site insurance and public liability cover in place, and agree who is responsible for safety and compliance. Fixed-price contracts offer cost certainty, while direct labour gives control but requires tighter cashflow management.

If you are self-employed, be ready with two or three years of accounts, up-to-date Revenue confirmations and a tax clearance position. Lenders will look for sustainable profits, regular drawings and a clear picture of future work. Keep personal and business banking tidy and avoid large unexplained transfers.

Other scenarios bring their own rules. Buy-to-let loans need a larger deposit and different affordability tests. Switching can reduce your total cost, but check any break fee if you are on a fixed rate and allow for legal and valuation costs. Joint borrowers and guarantors should confirm how the loan and the title will be held and ensure life cover and declarations match the ownership structure.
