I wanted to learn to wholesale so I went out and found myself a successful investor group.

That to me is true wholesale.. buy it and actually own it and then resell.

Does anyone represent a wholesale lender or is a broker that knows of a lender who finances commercial (multifamily) properties that operate as AIRBNBs?

Maybe any wholesalers, investors, fix&flippers, landlords willing to share any experience.I am a fast learner and willing to provide my business, trade for trade, to learn how to acquire my first property whether that would be a small 4-8 unit building or start big with a 20-unit building. 

There are a few options(1)You can get connected with the larger wholesaler firms in the area (2) go through PCPAO site and skiptrace the buyers of similar properties as yours, (3) hunt down the agents involved in the sale of properties similar to yours or go to local REI meetings and pitch it to the investors there. 

VERY unlikely unless you either source an off-market property yourself or you find a unicorn deal (our last semi-BRRRR was a B-neighborhood property we sourced from an out of town wholesaler in late 2023, but couldn't get all our capital back out on refi).  

I've heard about wholesale real estate as a way to get started without a ton of money, but Im still trying to figure out if thats the right move for me. 

Your best bet is to find and contact all of the top local wholesalers and go to work for one of them and see what they do right and wrong and see if it's even a business you like.

There are wholesalers in every major city in the country and they are buying at 70% to 90% of value all day long, every day of the week.

There are plenty of deals in Philly on and off-market from wholesalers, who are pretty decent in Philly compared to other places.You will need to get your GC license here and learn the permitting process and necessity here as well.
