Because the builders LO probably can't get an approval with a 600 score.
They need to work with Wells to get that done. I would think Wells could get this done very quickly.
Pre-Approval is when they run you thru the DU system and it says yes or no. takes just a few minutes.
But if you were in the 400s there is no way you would have made it thru DU, even at 600 you will probably not make it thru their DU system.
Wells should be able to get you pre-approval this morning and send you a doc to show the builder.
Earnest monies are different....we were required to plunk down $1k, but had to have an additional $4k within so many days. Hiring a realtor is your BEST bet. Going through the sales *help* can be a P I T A ! ! !
OP: This is all a learning process. If you don't get this house, there will be a better deal around the corner. Your time for homeownership WILL COME! Buying or selling a home can be SO EMOTIONAL, it's one of the most difficult things you will ever live through. When it's finished and you have the keys, it will be worth it. Stay strong.
If you do get your pre-approval, I'd use it as a bargaining tool to land yourself either a better deal, or more upgrades at a discount or builder cost. Contact the home office or have your realtor get her bat out, lol. Make this WORK for you!!!!!
