There are also many online calculators you can use if you do a search for them.

I'm trying to structure a deal for the seller but the real estate agent won't submit my offer to the seller because they don't think the offer is beneficial for the seller.

The seller is offering seller financing at 2% interest with a 9-year balloon.

Yes, I have done that several times, both as a buyer and as a seller.

There’s nothing special about the seller financing terms here IMO, unless you can’t get a conventional loan of course but if that’s the case the balloon payments create a high risk for you and you shouldn’t do it anyway.

Having the seller carry a second is not a problem for the first, as long as their business with you is finished and the loan has closed.

Quote from @Jim Rice: Would like to connect with Mortgage Note Investors/Buyers/Sellers of "Paper" (1st/2nd/PL/NPL) in SE USA (primarily AL/MS/GA/TN & Panhandle of FL).

Once the sellers accept the offers.. 

The auctions, although online now, are live foreclosure auctions, i.e. the auction style sale which is the culmination of the foreclosure process. 

If you want to connect buyers and sellers together get a license.New York has the most stringent rules for real estate.
