Seasoned Funds Relative Date

[Marlon Carabeo]

I'm looking to purchase a new construction build that's 8 months out. I was originally planning to put 5% down but with my DTI my broker said it best to put 20% down to increase my lending options.

I have the seasoned funds available in multiple accounts that are locked in. But I'd be in better shape with the 20% down in cash 3 months from now. 

My question is, What date do the lenders reference for the funds to be seasoned?

Will they require the down payment be seasoned from the application date, closing date or possession date?

Thanks in advanced!
