do you really think that a seller marketing their property at £300,000 would even consider something like £240,000? I found it very annoying that people viewing my property seemed to ignore the asking price and put in their own sill offers. So, my house being marketed at £450,000 - I had people offering £420,000.
Had a very good EA, and she knew that the lowest I would even consider would be £440,000. Did not even bother to pass on those silly so-called offers to me.
In fact, one family messed about so much with their offers, that I actually told the EA that even if they offered above the asking price I would not be willing to accept them, as I did not trust them.
If you are genuinely interested in that bungalow then the least you could offer would be in the region of £275,000 and be prepared to go up to £290,000.
Check how long it has been on the market, and also what similar properties in the area have sold at over the last year or so.
Will the sale of your house (with the current offer in place) give you enough money to buy this bungalow - taking into account, stamp duty on that purchase, solicitors fees and removal expenses - all added onto the costs of your sale - do remember your EA's fee which also has added on VAT.
