Most purchase money loans are provided by a bank, credit union or mortgage lender, or guaranteed by a government agency.
If you can’t get approved for one of those, you might be able to secure financing from a seller.
When a buyer and seller negotiate a purchase money mortgage, the seller is often flexible with the terms.
The seller might charge a higher interest rate or raise the price, but you could close fast and have low closing costs.
You might be able to assume the seller’s outstanding mortgage balance. If you do that, the original loan will have to be paid off first.
