2 Parcels, One Deed, Please educate me...

[Ian Bower]

I made an offer on a double, it turns out that it's on two parcels with two separate tax cards but deeded together. 

My loan officer seems to believe this means that I need two separate loans, sales agreements etc... 

My Real Estate agent believes that they can be sold together since it's a single deed... 

While they go back and forth, I wanted to try and educate myself on the situation. 

Can anyone here provide some insight? Since it's a single deed it seems to me that it would only make sense to do one loan/deal.
