Both have worked very well however I had some major stumbling blocks and my first "deal" I lost 100k.

If you purchase the "worst house on the block", it still needs to be (to use HUD verbiage) decent, safe and sanitary to rent.  

What do other properties on the block look like?  

In OKC, one block can make all the difference in terms of school district, gentrification and desirability.

Now, it gets better...On the same street and same block as mine, there have been several properties that have been retail flips that have sold for $125k - $140k.

I think it mainly happens with a long message thread then the grey box blocks reply button.

Part of the reason is that, aside from some blocks in some neighborhoods, these commercial spaces are very difficult to rent.

It is just blocks from the lake.  

Baltimore is a good area for investors but it takes a ton of research as the communities vary block by block.

The things we face with each project is to Revitalize the houses ability to be bought by the consumer or sold to an investor for a rental property, we are looking at doing 6 of these renovations in the next 6 months. with the sale of these homes in better shape than any other house on there block it will start a domino effect in the community, thus bringing in more houses, and soon the whole area will have increased it value.
