I've not made a comment like that about any post out of a thousand so I hope readers of this post don't interpret me as an abusive poster. 

So from a lender POV how I interpret that is you dont have enough personal or other sources of income to take a double hit from both mortgages so I would then figure out what is your qualifying income, how do we use rental income offset, and what steps are needed to do so.
