advise needed

hi,
we've planned to purchase a land then build to rent out.
we have the land settled and the building plans ready, but we are hesitated to go ahead with the construction as we found out i'm pregnant.
leaving work for some time, we have to manage in one income and we think we cannot cater making repayments
for the construction loan, plus knowing it's not generating income until it's finished and rented (which we don't know
how long will it be to be in that position).

can you please advise or share any inputs/thoughts what action we can do?
are we better off holding the land making repayments (investment loan for land portion as we didn't go ahead with the construction yet) while it's not income generating and no tax benefits? or
should we sell the land (we only have settled 2months ago) and exit the game – i'm not sure how much it has gained (if it does) now as we get in to the contract just last year?.

thanks in advance
