A yearly rent increase is written into the Lease Option so the amount I get increases each yearf.

I would require a SD in whatever the amount an eviction filing fee would be.

If it's a good enough deal, get an 80% bank loan and ask the seller to carryback 20% for a certain amount of time. 

Initially I only paid 10%.. but next day I paid full amount, got receipt from sheriff and some paper with stamp on it that says record of sale/interest....To me it seems like this is all clear even at this point deed has not been recorded, I told bank that I paid all the money to sheriff and they'll send the money to bank shortly...Is this all clear now for me to take possession ?
