I believe that areas to avoid are Druid Heights, Greenmount and North Avenue.To that end, I am nearing the completion of a RE sale in California and am searching for replacement properties in Baltimore that would meet the 2%-3% rule and comply with a 1031 exchange. 

So ALL of our sheetrock had to be taken down and replaced.

Nothing will replace the valley as the driver of tech.

My contractor who replaced laminate for the stairs claims that he remembers it being around 36 inch (as compared to 30 inch as per building code).

If you're lucky, there's not too much damage to the house, but you will end up painting and replacing the carpet.    

The Reverse 1031 Exchange allows you to take all the time that you need to locate suitable replacement property, buy and close on the new replacement property, and then you have 180 days to sell and close on your current relinquished property.

I went from part-time to full-time at University of Michigan an engineering tech III, concerned with building, updating and teaching college professors about the software applications of the late 1980’s.

It's a small house and I could potentially replace them myself, but not if the framing has little structural integrity. 

Just for potential notes: going by the numbers, the 4plex doesn't seem to have separate electric meters, both the fourplex and duplex looks like a roof replacement is due, some windows are boarded up (100% occupied)driveways would need to be added (currently a dirt lot)There is definitely room on the property to add another 4plex if zoning allowed (there is an apartment complex right next door so I don't see why not)even the third property has a good chunk of land behind it considering what the norm is here.There is a nice elementary school that is just being completed on the same street less than a few houses away.
