Selling our Rajkot home — capital gains tax ne pareshan kar diya hai

My lease ends in 4 months and I still haven't figured this out. We finally sold our big house near Kalawad Road, kids have moved out, so don't need such a big place anymore. Now looking for a compact 2BHK flat around Mota Mava or University Road, budget ₹60-70L. Problem hai capital gains tax ka. Builder log jaise Balaji Group ya Madhav Group projects mein to bas flat bechte hain, tax advice kaun deta hai? Koi bolta hai Section 54EC bonds lo, koi bolta hai new property mein re-invest karo under Section 54F. Honestly, it's confusing. Rajkot mein koi reliable CA hai jo practical advice de? Kitna time lagta hai yeh process mein, especially with OC and all?
