Financing or deal first?

[Sean Canada]

Hello Everyone. I am a contractor in the Central Florida area. I am a seeking to start investing in buy and hold rentals, target on small multi-family. I have been told by some it is better to have your financing before you push your lead funnel. Others have told me to focus primarily on finding the deal, make an offer on paper, then worry about financing...would love to hear from those a few steps ahead of me to see what they think. 

Thank you
