If your primary Lender allows second financing you might approach a Private Lender let you borrow some other money. 

Is there a way to use private money for Buy and Hold where you can pay back the private money (with interest) and own the property just yourself?

Be happy to chat privately about what little I know!

Hard money lenders many times will let you invest in their short term debt.. ( these are commercial purpose)One thing I get a lot of is direct mail.. its exactly the same method that real estate wholesalers use.they search public records.. get lists of private owners of notes.. ( usually the target is a seller carry back) and then they blast out direct mail offering to buy the note from the current note holder.. the pitch in 99% of those is all the same  same buzz words..

Also, private money is an option.
