Sometimes the Builder will require you to use their preferred lender in order for you to get closing costs from them. Their preferred lender should be able to do the VA loan also. It is worth shopping it around to see if there is a difference in the rates that would compensate for the different ways of paying it. I am assuming you are looking for closing costs since you don't have the cash available. There are two ways that is handled, one is the Seller paying (best choice when available) or wrapping them into the loan (the house must still appraise for the total loan amount- this may be easier with new construction but can't still be iffy).
Even with new construction it is good to use a full time professional real estate agent to guide you through the process and point out particular areas to look out for and ask questions. Interview agents till you find one you are comfortable with.
I feel an informed client makes the best decisions regarding their real estate needs. Let me know if I can be of assistance.
