You need to do as Solution 1 says or not make it an identity field and you maintain the mask.

I'd do this instead:

create table [cpqaAnswers].[cpqa].[tblPZResidential]
(
	--id varchar(max) primary key not null 'R00' + identity(1,1),
	id [int]identity(1,1) primary key NOT NULL,
	idx varchar(max),
	categoryid varchar(10),
	title varchar(max),
	images varchar(max),
	pdiscription varchar(max),
	contact_no bigint,
	city varchar(30),
	location varchar(30),
	property_type varchar(50),
	rate_persquarefit float,
	Layout_Plan varchar(max),
	Floor_Plan varchar(max),
	Unit_Plan varchar(max),
 
)

Then when it comes time to populate the table with data you perform a VALUES or INSERT of that 'R00' prefixing as "'R00' + CAST([id] As varchar)" in the appropriate place in the SELECT
