If you are constantly on the move or in less than desirable areas I would be hesitant to put my Macbook Air on a moldy/dusty/undesirable counter top but I would have no problem putting my $300-500 laptop on the same counter bc they are easily replaceable just in case something happens.

Atlanta as seen phenomenal growth.BTW the suburbs which were undesirable have also tripled. 

Even the lowest priced house still needs to offer any future resident safety and this area can lead to various very undesirable legal liabilities for the owner/seller.

If he wants the building to demo and redevelop, then he can choose to let his units stay vacant (or put some tenants in - this scenario works either way) and then let the building deteriorate until the other units are undesirable for rentals and devalued for purchases.  

Whatever the occupancy is today you should plan for it to go lower in the first year if there are undesirable residents that you need to cycle out.

Therefore that’s a slow and essentially undesirable market to even think about buying in unless it’s a low income area.

Latest news is that BS is going out of business at the end of the mont.In the last week I was able to obtain few pictures from the outside the house showing no work done outside at all, and I just can imagine what is going to be inside.So folks if you thinking of investing with Morris and Natali Morris from Morris invest run away fast or you'll get burned as I did.Now #claytonmorris  moved to new markets like Detroit Mi, Jacksonville Fl and who knows where elce, so be aware.At this point I am in the mud not sure what to do.

I guess the only concern is you are afraid of paying the improvement cost, getting undesired or unqualified "improvement", losing the ability to increase rent, etc.
