So much so that cracks are all throughout the house, it feels slanted when you walk through it, and the roof has come detached in one area that is allowing water to leak in.

By understanding what obstacles others have faced and how they overcame them, hopefully you can set yourself up for a good start.

In order to overcome those obstacles you need to make it up somehow.

My zoning is currently RS-3 which is "Detached single family homes and two-flats." 

Making the mind shift to go from the spectator status to actively getting on the field and participating is a huge obstacle for many.

I always hear the biggest obstacle is taking action.

The encouraging news is that Burbank and Glendale feature some large 2-4 unit properties with one of the larger units often featuring a  2-3 bedroom unit (often detached SFR).

No major fixes: roof is solid, basement is fine, detached garage may need vinyl siding soon.

I did a lot  of other Out-of-State deals in IN, IL and GA, site unseen... important is that numbers work, being solid, team, knowledge and always go through any obstacles that you will have., there is always a solution .  

Once the words 'cash-out' enter the refi purpose, costs and obstacles rise as well.
