We are entering the prime buying season - find other local investors and get their interest.With that said, there are a couple things that are unclear from your post. - The as is appraisal was for 275K,yet you are now expecting that it would be a reach to sell for 220K.

If your asset is older and/or smaller, you may have better luck with local community banks or credit unions.

Joining ULI/NAIOP in your local city could help too.

We put together multifamily deals locally, and also run a monthly meetup group.

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. 

Did you guys go to the local PD, DA, FBI, etc? 

I would recommend shopping around, especially with a local mortgage broker.

Other locals with similar experience had mentioned that this scenario might not be the best fit and it turned out to be correct.

It was just an offer (costs extra) through a local lender I used!

There's no fixed max size beyond local zoning rules.
