Always make your offer to the estate agent and not the homeowner. The estate agent has an obligation to check that you're able to go ahead. They'll check your details, for example your name and address, establish whether you're a first-time buyer, and whether your own property is sold, under offer or on the market.
The agent will ask you if you have sorted out a mortgage.
He will then put the offer forward to the homeowner and should confirm it in writing within 24 hours. The agent may tell you what amount he thinks the owner is looking for or if he thinks your offer will be declined. The agent is obliged to put all offers in writing unless the owner has instructed them in writing to reject offers below a specific amount.
If your offer is rejected, you'll need to decide whether to increase it or not. Are you happy to pay what they think the property is worth? And how big a mortgage can you afford? This is where having your finances arranged in advance becomes critical.
This process continues until either your offer is accepted, you decide that you don't want to increase further or you lose out to another buyer. In a busy market, properties sell quickly and may have multiple offers on them. The agent should not mislead you about other offers, but is not obliged to disclose the amount of any offer without the consent of the property owner.
If your offer is accepted, the estate agent will require details of your solicitor and will then write to you, the homeowner and your respective solicitors to confirm details of the sale. You will need to carry on with your mortgage application and your solicitor will start the legal work required. A good estate agent will keep in close contact with both you and the homeowner until contracts have been exchanged.
Even when you've made an offer and it's been accepted in writing, you'll have to wait for all the documentation and paperwork to be completed before you can assume the property is yours. Only when you have exchanged contracts with your seller and come through to completion, can you can start celebrating.
He will then check and negotiate the draft contract with your vendor's solicitor and check that the vendor has the title to the property.
Next, your solicitor will conduct local authority searches and send enquiries to the seller's solicitor. If this is satisfactory, all parties agree on a completion date. The mortgage offer, valuation report and survey should all be in order by now.
Your solicitor will then finalise, agree and arrange for the contract to be signed. You then pay the house deposit to your solicitor.
Once your vendor's solicitor sends back the approved draft "transfer" document, you sign it and it goes back to them. You're then ready to sign all the final documentation. If all is well and there are no further mortgages registered against the property you're buying, you're in business and the house is yours. All that remains is to pick up the keys.
