Perhaps take a look at:  https://www.loopnet.com/ and see which types of commercial lease listings interest you and from there take inventory of which brokerage and listing agents are prominently features in the space that interests you.

How is the appeal process like, and has anyone had success or non-success with the appeal? 

In fact, someone just called me last week and had a non-performing rental package that they purchased in the same fashion and the prices they bought at, considering the actual condition and historical performance of the properties was too high in my opinion. 

How cool.Well, It's because I was seen as a player, a closer (meaning I close on deals I put under contract).I said, "I didn't know you owned a building" and to that he said "yes, it's the building with two - first floor retail spaces and 9 apartments on the corner".Dang, just what I love.

I would be amazed, shocked even, if a traditional financial institution was willing to lend on a non-habitable asset up to 80%. 

If not again you would be better off buying your own home and having enough yard/space for all of them but 13 is still way to many dogs unless you live on a farm or own acres of land.I have worked in the banking business and have seen people lose their homes that they rent due to landlords kicking them out with very little warning due to breach of contract or a No pet rule. 

@joel, FHA will finance non owner occ??

I designed a little U-shaped kitchen to fit right in the space.

I would suggest leasing a commercial space for your business first before you go straight to purchasing a space.
