I want to sale my 2 x plots to buy 1 x 10 marla possession plot in bahria t

I live and work near faizabad, rawalpindi. I own 2 x plots in bahria town phase 8, i bought them back in 2013-14 for the purpose of house construction.

1 x 5 marla is in L block (no: 148*) and

1 x 7 marla is in L block (no: 604*). I would like to ask 'respected experts' the following questions

I) is this good time to sale these two plots and buy 1 x 10 marla plot in bahria town for purpose of house construction (i am looking for plot having possession but will start construction after 4-5 years) ?

Ii) if yes, which block of phase 8 is best to buy in this budget, i want to buy where there is solid land i.E. Cutting area and near to main entrance?

Iii) also is there any similar option available in bahria enclave islamabad that falls under by budget ?

Thanking in advance
