Closing costs often catch first-time buyers off guard because they are paid on top of the down payment. Many buyers can negotiate seller credits, and state and local housing finance agencies frequently offer down payment assistance with income or purchase price limits. Lenders also look at reserves, meaning the savings left after closing, so emptying every account can weaken an otherwise strong file. Credit deserves a review well before applying, especially for recent late payments and high card balances. Small cleanups made months ahead usually help more than rushed fixes during the final stretch.

Rate movement is the part of the process buyers worry about most, and it deserves a plan rather than a guess. When rates are moving day to day, the bigger risk is a closing that slips past the lock period. Ask your loan officer about lock terms that match your contract timeline, and ask whether a float-down option is available if rates improve. Buyers who keep some flexibility in their price range can absorb a rate swing without losing the house they want. A rate only helps if the loan actually closes on that home, so the timeline should carry as much weight as the pricing.
