Will I be denied in underwriting for an $8,000 cash deposit?

if you are not able to document the 8K - you should be able to ask your lender to back it out of the transaction and not use it ....this might cause your loan amt to increase to above 80% lTV so it might create aneed to pay for monthly mortgage insurance and also change your locked pricing a bit ....this shouldnt be s csudr for declining your loan ( unless you have qualifying ratios that are already at the max level )

You've discovered a common mortgage loan problem, that being that CASH is NOT an acceptable form of down payment. The simple problem being, is we can not prove where the money came from. The best advice is two fold... One, keeping that much cash at home isn't really a good idea, and that for mortgage purposes, once the money has been in the bank for at least 60-days, I don't need to prove where it came from. Finally, there are many tools in the toolbox for work arounds on this... But it is also a good time to talk about picking a good Loan Officer... Someone who would have, and should have discussed with you in the pre-approval process about cash deposits... I lend in WI, MN, IA, ND, SD.
