As Hank mentioned earlier, there is an abundance of information here!

There is an abundance of information available to you on this site and many people will offer advice and recommendations. 

Gone is the HML to refi ( at least in any great abundance) and what you have now is a more educated buyer who wants the home done and tenanted to alleviate risk..

A win-win.I also happen to believe their is an abundance of opportunities rather than a limit supply.

Case law is abundant for issues involving produce the note theories, MERS, and loan assignments.

1- AZREIA (Arizona Real Estate Investing Association)2- I liked the abundance of newbs who were desperate to give you their 'deals' because they were too scared to take action themselves.

Thank you all for the abundance of information.

The type of MF areas you mentioned you are looking for (blue-collar and above) exist in pockets, but really vary block by block.If you're at all interested in SFHs, there still seem to be an abundance of great B&H investments opportunities there in and around KC.Best of luck!

I'm very excited about all of the wisdom, abundance of information provided on BP.

In my opinion the major setbacks you are going to hit will be:- Size of your lot (DCRA typically requires at least 900sf per unit you want to build- but there are some ways around this-- this is not 900sf of living space, but land)- Your Zoning (if it's R-4 then you're in pretty good shape with regards to being able to build a pop up and as John said if there are properties in your neighborhood with a popup, which Columbia heights has an abundance of, then Precedence really helps)- Extending the back of the house will be difficult as would underpinning the basement to deepen it- not so much because of zoning requirements, but more from a cost and technical implication as it's always a pain when you mess with the foundation of these old houses.If you want to talk about it more in-depth shoot me a message and I'd be more than happy to discuss further
