@Patrick Roberts & @Tim Delaney- which lenders/ loan types are good for 80%?

That translates into $208 to $375 per month on a $100,000 loan.

However those with no to very limited experience will never get a fix and flip loan  from a bank. 4.

You could also use a Fannie May Home style renovation loan which a conventional loan and require 5% down vs.

Are there specific lenders or servicers that are more likely to call these loans?

If you are going to be an owner-occupant, want a low down payment, and are planning to do a renovation, the FHA 203k and Fannie May Homestyle loans are your best optionsHow do you know the property is currently upside down on the mortgage? 

This term replaced "subprime" and looks a lot different than subprime loans of the past.

You could get a loan from a local bank or private lender to fund it

I know that interest on the acquisition loan can be included in the cost basis since it’s inventory.

Would a HELOC or home equity loan on my personal home be a good idea to fund this?
