So area wise I would say cass county MO or southern Johnson County Kansas. 

I have a mid-term rental in Southern California near the beach that is consistently losing money each year.

There aren't many co-ops in Southern California, mostly in LA or a senior community in Orange County, but there's not much of a discount between condos and co-ops - at most, 10%.What is your source of the 10% difference data?  

To any experienced investors willing to show me the ropes a little more in detail be more then happy to message me, I live in the Southern California area to be a little more precise.

The other markets are in southern states.My buyers are typically the "trades".  

By 2030, we want to have grown a portfolio of over 100 units, created a property management company that manages an additional 100-200 units, and, finally (and most importantly), we will have established a non-profit that is focused on quality, affordable housing that specializes in providing housing and resources at/on the "services cliff" alongside financial counseling and first-time home buyer education in our target area.Our target area is the Springfield, MA and Hartford, CT areas with dreams to expand to Central Massachusetts (Worcester, MA), Southern New Hampshire (Nashua, NH), and Southern Connecticut (New Haven, CT).Would love to meet up with likeminded individuals in our area!

I ask because we only buy houses around the southern US (TX,OK,AR,TN) but we're curious to know if more opportunities to buy foreclosures could potentially exist in other markets. 

Quote from @Eli Epstein: @Al Boettger I am in southern NJ near Cherry Hill. 

I am an aspiring serial house hacker based in southern New Hampshire actively searching for my second small multifamily deal in the Nashua area, but I've hit a wall with inventory being so tight in my local market.

For example in Southern California many apartments do not come with refrigerators.
