Consequences of not filling air in itr-2

There no problem for not filling the details of purchase of property in the ITR. So forget about any consequences to that.

Now let me come to the crunch part:

you say that you have not shown any income in the return filed, then first question that will arise is the source of money from which you purchased the property.....

this will entail you in difficulties if you dont have explanations to the source.....

So get details of how you got the money to invest in property.
