Based on the information you've given so far....
• If you work from home a lot, the feel and layout (or potential layout) of your home is important.... you'll be spending a lot of time there. Take a compass...a north facing flat is brick. Good light is your friend
•your surrounding community is important as well (you'll be spending a lot of time there

). Is there a potential network of coffee shops , cafes, bars, parks...not to socialise BUT to get out the house and work from. Cabin fever is a homeworking problem. Plus the usual, doctors , dentists etc.
•with that in mind it is nice to live somewhere that doesn't require getting in the car all the time. Parking is brick and generally costly. I walk but oftentimes get the bike out (increases the range of journeys). Is that an option?
•also that can delay the need (and cost) to get a car straight away. Weigh up your options first. Is there Zipcar in the town? for short term rentals ...
(Sublet your garage

•Any flat you view ....first thing, check the phone signal...needs to be solid.
•check internet options...fftp fibre etc
•If your a non chain buyer with a mortgage approved (in principle) leverage that position...in most areas it's a buyers market at the moment. I think Zoopla have a listing timeline so you can see how long a property has been on and if and when it's been reduced (I think PropertyLog iirc is a desktop extension that does the same with Rightmove).
•as someone else said try and assess the neighbours.
•heart, head and gut are your decision making tools try and balance them accordingly..NEVER be too emotional or volunteer anything you don't need to to the estate agent... they're all clams.
