mmmm i think,for a municipality, i guess it will be a certificate of lease. u only need to pay the arrears of rates, u get a clearance certificate, and then the rest is processing fee, say less than 15k, for a plot valued at 200k. But its the owner who sold to u, who should pay the rates and give u a clearance cert. for ur plot.
If its a freehold, then again u need the seller to give u the individual title deed of ur plot, since the bigger title is now obsolete... then 4% the value + bondfees+ facilitation fee, 20k on the higher side, and u will have the title...
