No. As long as each account stays under FDIC insurance limits, that money is safe, and spreading it out costs you nothing but a little paperwork. The FDIC insures deposits up to $250,000 per depositor, per insured bank. Keeping each balance under the cap at separate institutions means even a bank failure would leave your funds intact. What deserves your attention is the paper trail at loan time: - Expect to provide the most recent two months of statements for every account you draw from. That is the standard documentation window across programs. - Any large or out-of-pattern deposit gets sourced no matter how long the money has been sitting there, and transfers between your accounts need to be traceable from one statement to the other. So keep earning the yield, stay under the insurance limit at each bank, and hold onto your statements. When you are ready to buy, we will help you document everything cleanly so the funds are ready for down payment and closing costs.
