Help! Source of Down payment from Sale of Personal Property?

[Alfred Litton]

I'm in contract on a SFH and would like to use cash from the sale of inherited personal property and the sale of some of my own property (gold and silver and other collectibles). If I receive cash for this and deposit it into my checking account, with the lender think this is odd or not kosher? Don't want to look like I robbed a 7-11 or that I'm a drug dealer! Would most lenders be okay with that being the majority of the 20% down payment??
