Buying and selling personal residence strategy?

[Justin Mespelt]

I'm looking at selling my personal residence and buying a new home. Most of my down payment is the current equity I have in my current home. My big question is how willing are banks to acknowledge that you are selling your home when approving you for your next mortgage? Without selling my current home my debt to I come ratio is not going to allow a new mortgage. My wife is self employed so that messes up our provable income also. 

I live in a hot market so I believe my current home can be sold quickly. Would you suggest just selling it first? Finding a temporary rental sounds like a pain in the *** considering we have a 3 year old. 

HELOC? Bridge loan? Seller contingencies in a really hot market? Renting back a home after you sell it? All ideas, none great.

Thanks
