Step 1 - make an appointment to see a mortgage adviser (Estate Agent's usually have one) to find out how much they will lend you.
Step 2 - Armed with this figure plus any savings you have, you can then make appointments to view properties in the appropriate price range.
Step 3 - When you find a property you lobve, you can make an offer. Typical offer might be 10% under asking price, but would depend on location and demand. First time buyer properties in my area sell quickly at over the asking price.
Step 4 - Once you find out if your offer has been accepted (or you've renegotiated the price), you will be expected to instruct a solicitor to act on your behalf for the purchase.
Step 5 - The Estate Agent sends a Memorandum of Sale to the seller's solicitor and your solicitor to get the ball rolling.
Step 6 - The seller's solicitor will send your solicitor a draft contract pack with initial information about the property.
Step 7 - You decide on the type of survey you want i.e. valuation, home buyer's or full structural and arrange for it to be done via the Estate Agent.
Step 8 - Hopefully you would have decided on a mortgage lender and they will make a formal mortgage offer to you and instruct your solicitor to act on their behalf as well.
Step 9 - You will need to decide on searches, which must be paid for in advance. If you are taking out a mortgage then some searches are obligatory, i.e. Local Authority, Environmental and Water/Drainage.
Step 10 - You have time now to let the solicitors do the legal bit. You can get quotes for removals (if you have any furniture, of course!). If you have a Help to Buy ISA, let the solicitor know so that they can set the ball rolling with getting the bonus paid (but be aware this cannot be used as part of the deposit). You will need to close the account and get a closing statement. If any funds are being gifted to you, then the person gifting will need to write a letter to the solicitor stating the gift is not a loan, and that they will have no rights over the property. Also make sure the solicitor has received your ID and is happy with it.
Step 11 - Assuming all enquiries and paperwork are satisfactory, your solicitor should send a report to you with information about the property, as well as instructions regarding paying stamp duty and the deposit. You may also receive the Contract and Transfer for your signature (and witnessed) which you will need to return.
Step 12 - Once the signed Contract and Transfer are in, deposit received and satisfactory responses to queries, the solicitor is ready to exchange contracts and set a completion date. Be aware though that if there is a chain above you, they all need to be ready too.
Step 13 - Exchange Contracts. This is legally binding. If you back out now, you will lose your deposit. Now you will need to insure the property and if you do have belongings to pack, now is the time to do it. You can advise people of your new address - including the utility companies, council (council tax), DVLC, Banks/Building Societies etc
Step 14 - Completion. Once monies are received by the buyer's solicitor, they will release the keys and you can go and collect them (usually from the Estate Agent) and move in.
Hope the above is helpful. Obviously not all house moves are smooth but generally this is what is supposed to happen!
