HML AND OWNER FINANCING

If the owner still has a mortgage and is offering seller financing could i still recieve a hml for downpayment and rehab, because it may be a chance the property will still be in the owner name

You would be better off just funding the entire deal through a HML.

I do not see this happening. Why would someone want to lend you money towards a property that you do not have any ownership in? and you want to use that same property, which you do not own, as collateral.
