What’s my best financing option for this 4-Plex?

[Jenny M.]

I am a first time investor. I am trying to structure an offer on a multifamily rental property in San Bernardino county. I want to create a no money down financing option where I can walk away with cash at closing for rehab and costs. I am uncertain about whether my running numbers is entirely accurate, since I am missing some details for my preliminary offer. What is the ideal kind of financing to pursue for this kind of deal? Also, who should I approach to check my math? Thanks guys! Any suggestions very much appreciated!!
