How does buying a wholesale when Financing is involved

[Carl Evanko]

I am looking into buying either a multi-family or SFR as my first investment. I am trying to learn as much as possible with methods to start/finance etc. In my search to find good multi-family deals, I keep discovering that what is available on MLS in my area isn't the greatest when all factors are concerned. Wholesaling has come up multiple times in reading/ listening to podcasts, and I am starting to learn more/go down the wholesaling rabbit hole. Wholesaling, in general, is a very interesting idea/concept. So I am thinking about seeking wholesalers or target marketing to those multi-family property owners. Can anyone with experience in this avenue of Property Investment shed some insight? If I am interested in buying any property from a wholesaler, how does financing work in that kind of arrangement? Would it be more advantageous to market directly to Property Owners and then choose to rehab/rent or wholesale the property myself? If I direct market to owners, again how does financing work if I intend to rehab/hold or flip the property?

Also, are there multi-family specific realtors I should look to find in my local area, or will any top realtor be ok to deal with when searching for multi-family properties?
