Quote from @Paul Lucenti: Creative methods tend to increase risk.

I would read up on the risks before collecting rent with those tools.

The risk is far lower, with a better ROI.OR you can consider learning about government contracts and performing lease matching. 

So investors want someone with a long track record of reliable and risk adjusted returns.

I think you have to find what your strengths are and what your risk tolerance is in different areas of RE and look at your entire financial picture.  

So sad...... what is scary too is they only have them 10-20% contained and they are expected to get high winds again which can carry those embers pretty far. you also have to think these fire fighters etc. have been working around the clock and must be exhausted.
