I wouldn't adjust for inflation – defeats the purpose, turning housing into an inflation-proofed investment: if you want one of those, govt stocks should be your option. I also wouldn't allow for the deposit. Whether or not you borrowed to buy or paid cash should be of no concern – allowing you to keep the deposit would specifically allow rich people to speculate and avoid the tax – also defeats the purpose. (Remember the tax is only on profit, not the whole price – and if you are just moving home, you're allowed to take off the price of the place you buy as well. This is only directed at profit.)
The problem with only allowing receipts to be taken into account is that this doesn't allow for people doing up a place themselves.
ETA:
Unless you paid more than 100% deposit, you would always be allowed to keep the deposit anyway.
