It is not a simple answer---a minority interest (which is what a 10% stake is) is typically discounted for valuation purposes. Is your 10% interest freely transferable or permitted to be pledged as collateral? (most private LLCs typically have transferability restrictions of some sort).

Put another way, that potential $1M of collateral isn't very meaningful to a lender if the lender has no way of accessing that value.

I couldn't but my assets were essentially work in process and accounts receivable which would turn in to future income and my income was already being counted.

If the assets are liquid, then yes. When I got my latest loan, we included the value of the bank and brokerage accounts of my company in the asset listing.

No liabilities- so my equity is 1m

Does it have liabilities too?

I am a 10% shareholder of an LLC with assets of 10 million. Is this holding able to be counted as an asset for mortgage qualification purposes?
