I am going there tomorrow with a Crawl space specialist and if he
comes with issues then will not go for closing

The home inspector has stated in the report

FOUNDATIONS (Report signs of abnormal or harmful water penetration
into the building or signs of abnormal or harmful condensation on
building components.)
Repair or Replace

Visible signs of water intrusion in crawlspace along front of home are
present from damp/muddy conditions, standing water at footings located
(right of main entry), and from standing water at lower left corner.
Water intrusion can lead to more costly repairs and increase damage if
not corrected. Also, verify from builder the foundation drain extends
to daylight. Recommend builder evaluate and provide the necessary
corrective action (See Pictures)

As you said before the home inspector is last line of defense

I will be taking the purchase agreement to a Real estate lawyer to
study in more details

Thks everybody for all the help
