To answer your question. The gain on the property say at 14/9/1020 is £750K - £100K so £650,000 you have CGT PPR apportionment of 194/341 so a resulting gain of £280,208. From this we deduct the Letting Relief ( 2*£40K ) so £200,205 now we 1/2 it and deduct the individuals unused CG Allowance presently £10,100 then tax the gain at the individuals marginal rate. Thus the figures I gave you £24,530 and £23,083
Now lets say you moved back in for 5 years and you spent £100,000 on capital expenditure/enhancements, like a new extension, a second floor, a conservatory and a detached double garage. Then you sell it for £1,000,000. So you have a gain of £900,000 - £100,000 enhancement so £800,000 and a apportionment of 218/401 so the gain is £365,087 - £80,000 LR then halved and your unused CGA deducted and then taxed at your individual marginal rates so around £36,643 and £35,197.
As you can see your gain has gone up considerably but the CGT has only risen by around £24,227 for a gain of £150,000 ( 250k - 100k(enhancement)).
I hope those number help you to understand your situation and allow you to move forward. Also please be aware that any disposal of your gardem for building will not be free of CGT by the same apportioning rules. Read http://www.hmrc.gov.uk/manuals/cg4manual/CG64208.htm
For clarification.
