Is a 203k loan a good option?

[Tre Reaume]

First post and just stepping into the vast world of real estate. Yay. And yikes. 

I am looking at a property that needs total rehab, but whose guts are good. I know this from 2 contractors who I have had walk through the entire building. Both gave it a green light. We even had a mason look at it (brick building) who already gave me an estimate on how much some necessary brick work will cost.

It is a mixed use, commercial on bottom, and apartments on the 2nd and 3rd level. 

Asking price is low as it should be. I suppose my question relates to the best way to finance rehabbing the property. I read about a 203k and it seems to be a good fit. Is this a good road to go down? Are there other options? Can anyone think of questions I would be wise to consider (ie, projected rents from both units, projected income from business on 1st level, estimated rehab cost)?

THANK YOU!
