Seeking financing advice for financing a Marietta, GA triplex

Good evening,

I've located a multi-family, a triplex, in Marietta, Georgia, and have it under contract. Unfortunately, I've now learned that its location is not zoned for multi-family. The lender I have used in the past has told me that in order to lend on it, I either have to:

1) Have the property properly rezoned to show that it is a multifamily (probably not practical and certainly can't be done in just a few weeks)

2) Convert the property back into a single family home and get all of the current tenants under one lease. This is doable, as only a doorway would have to be opened up to convert it back into a single family, but as I don't own the property yet I really can't do this at this time either.

Does anyone have any financing options they could suggest for such a situation? All three units are leased at $650 each ($1950 total) so it's really a great cash flowing property at my contract price, but I'm in need of a new lender at this point.

Thanks in advance for any and all advice.
