Jackaranda welcome to this thread. Do hope your journey in the coming year is going to be a happy and successful one. Just think, this time next year - you could well be well settled into your new home.
Do take some time, and read these threads right from the first one, as you will learn of the many heartaches and problems that can occur, although most of those earlier contributors are now well settled in their new homes.
Many EA's overprice a property in the first instance, in order to persuade you to go with them as sole agency. Then after a few weeks they come back saying that YOU are asking too much and you now need to lower the price
With regard to purchasing property at a distance, you need to really ensure that you climatise yourself using sites like rightmove. Get to know properties and property prices in the area you are looking. Know the tick list for the properties you would be interested in viewing. Most Agents will not permit you to view or accept an offer until you have a firm offer on your existing property. So, whilst waiting for someone to make you an offer, just use your laptop/tablet really to get o know property in the area you are going to.
In the meanwhile, start to get rid of loads of stuff. De-cluttering fully can take several goes. Downsizing can also mean requiring new furniture. Be really strict with yourselves in getting rid of things.
Be prepared for disappointment, people do pull out of purchases, often quite late, until contracts are actually signed and exchanged, nothing is definite. Work out your finances carefully, what is the genuinely lowest price you can accept on your existing property in order to purchase your new home. Be realistic about the costs of moving - there are Estate Agents Fees,Solicitors fees, Removal Company costs - and these will be considerable with a move over such a distance. Do not penny pinch on these, as you are older pay out for the company to do the packing for you, and sometimes the cheapest quote can turn out the more expensive if the company is not a good one.
Work out your check lists for a property you wish to purchase -ensuring it is well future-proved. (Near to shops, public transport, pharmacies, not too far from local hospital, GP surgeries, dentists, etc. etc.). Work on the fact that you may, either one or both of you, be able to drive in a few years time, either no or not too many steps/stairs. Showers or wet rooms rather than baths. Economy of keeping property warm (energy prices are going to increase).
Three lists, (A) Must have (B) Desirable to have (C) Can compromise on.
The chances of a perfect property to buy coming up is remote. BUT.....think about how you can make any new property your purchase perfect once you are living there.
Allow a goodly sum of money you will find yourself needing to spend in that first year or two in the property. Most of us have found this to be far larger than we had reckoned, on changes, decoration, curtains, flooring.carpets, new furniture, etc. etc.
