Well assuming you have either
A) Enough cash to cover the costs - £215K + factoring solicitors (including searches and surveys) at an average of £1500 then SDLT at 1% (£2150) plus any other costs, moving firms, insurances both life and buildings as a minimum.
B) Already got an AIP to cover at least the full cost of the house + min 10% deposit of £21500, and all of the costs above covered.
Then IF and only IF you can see yourself living in it for at least the next 5 years, I would proceed and just get it taken off the market with no further viewings (insist on this if your offer is accepted), before someone comes in and offers asking price on it.
