How to get funding? Will LLC help?

[Austin Minor]

My wife and I want to move to a new neighborhood/bigger house to accommodate our growing family (4th baby on the way!). 

We have two rentals, both of which are under 1 year old with no taxes filed on them yet. When we move we would keep our current home and rent it out. All our rentals cash flow very well, however we would need proof of rental income in order to buy our new house, otherwise we will have DTI issues. 

Is there a way we can get around this? Will it help if we move our rentals into an LLC? Is there another work-around? I don't want to sell any assets in order to move.

Thanks!
