Let prospective investors know that you have succeeded at something. 2) 3rd party validation is key - We were able to use news articles, travel websites and new airline routes as collateral information to prove to investors that what we are saying about our market, others without a vested interest are corroborating. 

But if you overpay by as much as 20k on a 110k asset, assuming you put 20k down it wouldn't take that large of a dip for your houses appraised value to drop below the value of the mortgage at which point the bank may call your note due in full because they no longer have adequate collateral.

I just purchased my second rental using collateral and nothing down.

Well…..notably already here: Walmart Foundation and a soon to be medical school sponsored by them, Crystal Bridges, renowned art museum, Arkansas Childrens Hospital (magnet hospital) alongside all the innovation and creativity from the collateral businesses that operate alongside the huge businesses like Hunt, WM, and Tyson.

We have accumulated a large some of equity in this home.1) Could we pull money out of this property and use it as a down payment or use the home as collateral for a multi family unit?

The property is just their collateral and Hard Money Lenders do their own due dil and it's VERY expensive!

Most hard money lenders will allow equity to be used as cross collateral for other deals.

Your free-and-clear property would be the collateral and the loan would be in the form of a construction loan.

From the perspective of creative financing is it possible to obtain 100,000 dollars via a dscr loan and utilize a Completion Bond to serve as collateral that I would have to come out of pocket for which should be 5,000.

It is highly unlikely a brand new business could get a loan (if there is no other collateral involved).
