Tough to find a lender to do that.When you talk to lenders the term you want to use is "cross collateralization".

You can get a business line to avoid personal collateral.

so in essence a flooring line then when they are sold he signs them over in exchange for his principal and his return.. usually 15 to 18% interest on those.. got to choose the used car dealer wisely of course.. they have been known to fudge titles and your collateral has driven off without you getting paid.I also have a client.. they happen to own a few Toyota stores in Oregon but one of their business and I think it could be one of the largest on the west coast is they buy sub prime auto debt... you know the kind were they put the chip in the car and also a little do hicky that flash's when the payment is due  and then when they are 15 days late or some amount of time the car is disabled.. so they can use the chip to find it and its disabled and they can just go and repo it.when I was in Jackson MS I asked a used car dealer there that I met at my watering hole.. how the heck do you sell cars for a 100 down 100 a month .. he said  SON  my clients are born live and die all within in about a 10 mile square area here and the key is getting their mom's name and number.. we just drive around till we find it or call mom and get the whereabouts..

Also from non collateralized debt to collateralized debt. 

Used another property as collateral.

But they want to know what collateral I will provide.

Need to raise Capitol for down payment of the deals I've been watching. As of now csnt get anything I can do by my self . So I sant to ask friends and family for 10k loans with 10% yearly return . I want to get a let...

Easy, if you have collateral, such as other free and clear property, or equity in other assets.  

There is plenty of private money that would lend 50 to 65% LTV so long as the collateral is decent and you're a decent human being.You should also consider encumbering that property for asset protection

Yes - you can - sell a partial or get a collateral assignment loan from someone.
