If you are buying without a pre-approval letter, you are shopping with Monopoly money. Here is why it matters — and how to fix it before your next showing.
What a pre-approval actually proves
A lender has pulled your credit, verified your income, and committed (conditionally) to lending you up to $X. It is not a guarantee — it still depends on the specific home appraising — but it tells the seller three things:
Why FSBO sellers especially care
A seller working FSBO does not have an agent screening buyers. If they accept your offer and you fall through at the lender, they lose 30+ days of market time. They will pick a pre-approved offer over a slightly higher non-approved one almost every time.
How to get pre-approved fast
It takes 24–72 hours with a prepared buyer. You will need:
Run the application through 2–3 lenders at once (within a 14-day window the credit bureaus treat this as a single inquiry). Compare rates, lender fees, and estimated closing costs. The cheapest rate is not always the best deal — a 0.125% higher rate can easily be offset by $2,000 less in fees.
What to do with the letter
Upload it to the Deal Room on OpenList USA when you activate one. That single document moves you from "interested party" to "qualified buyer" in the seller's eyes instantly.
