You need a Buyer's Agent and you need to get pre-qualified. If you plan to go through the "Buy Springfield Now" program (the best Springfield program for 1st time home buyers), please contact me for a list of participating Lenders.
Now you need a buyers agent who can help direct you. But as to lenders do you belong to a credit union? If so that would be an excellent place to start. If not, I might start at the bank I do business with presently.
