House and land was on for £800,000. Was lowered to £675000 a few months ago. We went to see it a couple of weeks ago and they offered to split into lots. House and garden under stamp duty threshold at £499950 and garage and land £165000.
So, we offered asking price on the house if they pay the stamp duty (15000) and to rent the garage and land for a period of up to four years with a option to buy in that period for asking less rent paid.
They rejected offer saying, they would agree to renting and subsequent sale of garage and land but want full price for house.. 
We will really struggle to find another £15000. What to do? It's perfect for us
