They are all the same basic design on the same estate. My view
Number 1 is mid terrace and no drive, plus a dodgy looking bay window. It is staged to sell, and over decorated for the area. Is it at ceiling price for that street? The kitchen diner knock through looks a good idea to me. As lovely as it is, don't be blinded by decor and garden. Will you keep the garden and decor? For how long? It is mid terrace and no drive.
Number 2 is end of terrace so wider garden and side access, although all seem to have rear access. Drive is worth car insurance savings. Plus if you cover the side passage you have somewhere for bikes. Decor and conservatory are ok to live in, but mid term some expensive work knocking through kitchen and dining room, and possibly removing conservatory for a real extension. Garden needs work, but is level so toddler friendly and can grow with you over the years.
3 is a complete refurb, so only buy if a serious Diyer or in the trade. Trades are expensive right now with corona so unless really really cheap, avoid. It isn't cheap enough compared to 2.
I'd prefer a north garden to East, depending on neighbour trees. I've a NNW garden which gets evening sun. An east facing back garden in the uk is rubbish.
How long is the house for? 2 years then 1 might be best, but negotiate down based on 2. 2 years or more then house 2, but negotiate down based on 1's work and cost to remove conservatory. If you are a builder then house 3 with a hefty discount.
Good luck, nice to have options!
