@Jeffrey Ward This is a fairly common conversation among Baltimore real estate investors and if you search in the archives you will find more versions of this conversation.
I can only speak from my experience, which I would say has been moderately successful. I have owned about 15-20 of this caliber property in the last 24 months and my experiences have been mixed. I have 1 that I bought for 25k put 5k into it and it rents easily at 950 with the tenant paying like clockwork.
I had another one that I bought for 8k put 40k into and have it rented section 8 at $850. The problem is that I can not refinance it so now I am selling it to get my cash out. I am under contract to sell it at 5k loss because the block is terrible. So, if you are going to try these areas it is wise to make sure you have an exit strategy. I have another similar one that I bought for 4500 put 20k into and sold for 25k. So while it feels nice to make some improvements to a block and help to stimulate the economy--it is not exactly a business success.
I am in the process of doing a block of 10 houses and this where the real money is because you can control many more of the variables. You have better control of your comps which helps with resale and refinancing.
I have been doing this for 2 years and I am still learning, so part of it is just putting in the time and figuring it out. My take on the broader situation tends to fluctuate but I believe class C/D investing in Baltimore City if done in a targeted, professional, and consistent way is a giant economic opportunity. I disagree that appreciation is off the table in some of these areas. I'd actually be willing to bet that in the next 10 years you will see greater % appreciation in an area like Lexington around the West Baltimore MARC station than you will in Canton unless Baltimore can figure out how to solve it's property tax problem.
To summarize, I think onesie-twosie investing in C/D areas is not worth your time. Unfortunately, for the onesie-twosie investor this aspect of the market is most accessible because most people with some ambition can save or borrow 10k to buy one of these houses. That is extremely risky and foolish to do. My sense is that there are chosen investors and contractors that operate within a system that is corrupt in Baltimore that will get the vast share of the value in the redevelopment of the C/D areas that will be redeveloped. One other thing to include about Baltimore is that given the demographics, geographics and sheer volume of the problem at hand there will be areas that will not be redeveloped and will eventually need to be razed.
This is all not taking into account the fact the city of Baltimore will face a huge budget shortfall, which will lead to more problems in solving basic city problems. We can only hope for a big change in leadership, that the city declare bankruptcy and cede its political power to the county and state, some kind of large federal spending program targeting poor areas or some kind of combination. I have zero faith in the city's ability to solve the problems of blight and crime in Baltimore. The problems are too large and I think the politicians are not capable to solve them.
