Buying a newly built house from owner recently closed

[Prasa Kon]

Hello Experts, 

                      I am seeking your insight into buying a newly built house from an owner who recently closed the property from a builder.

                     The seller listed this house as a primary residence but never lived there, as soon as he closed the house, he put it on sale.

                       Looks like the Seller lender is asking for pre-penality charges and would have to wait at least 3 months to sell the property.

                       I am already in contract to buy this house, not sure if there will be any issues, they are saying if I go through a different lending company than of the seller's lender then closing wouldn't have to be delayed.  please let me know if there are any underlying risks or issues with this, that I cannot foresee . I appreciate your inputs.
