Where are you going to be when property values decline and rents along with them. Then you are collecting less rent but payment not going down.

Wait for a better time and deal.

Sure you plan to keep it forever and it will work out in the long run but still I wouldn't do it.

You probably know depreciation will help out with your taxes which is good. Plus any other tax writeoffs if you can use them. You might be able to breakeven unless rents drop then it's who knows.
