Seller offering Owner financing to then bank financing

[Juan Bravo]

Hi BP community!

Ok, how do I start?... I found an incredible farm that I'm trying to purchase in Puerto Rico. It is owned by a group of investors and seems like they're very motivated to sell. When talking about financing, they do not want an earnest deposit. Instead, they are saying that they will sell me the property with an owner financing to assure the sale (and not wait for a bank loan approval) of the property and after that I can start a bank loan application to get a conventional financing and get a more comfortable payment. I'm ok with this because I want the property. However they are asking for me to pay property taxes due and minus it from the sale's price. Here's where I have a problem. 

If I carry the tax debt from this property I will not have the money to pay it off right away, thus bank will not finance (because it's not free of debts) and then I will be stuck with the tougher payments from the owner financing agreed to. 

Can anyone with knowledge on the subject help out this newbie? Any advice on things to be aware of here? Any Puerto Rico RE attorneys that can help?

All best,
