Seller Financing & DSCR loan

[Yusuke Koike]

Hi

Does anyone give me a professional advice on seller financing?

As you know, recent interest rate has been increasing. 
This increase killed my deal so many times. 

Do lenders generally NOT allow a borrower to bring a down payment by using seller financing?

e.g. I purchase a property at $300K

1. Seller accepts seller finance for 40% of the price.
2. I will put a 10% down.

Do you think there is a lender who would be able to fund another 50%.
