On 18 months that would translate to somewhere around 10%.

Its always helpful to translate percentages into dollar values to see if they make sense.

I have been to the alter twice but never sealed the deal.   

Here in California, my experience and research shows me the 70% rule very rarely works out, homes are just too expensive that that 30% discount we hope to find translates to hundreds of thousands, and those deals don't come by that often. 

Speaking to my solar rep, I can get a small system for about $10K (which translates into a $3k tax credit); but I believe the return on this would be at least 100%.

I've seen good Risk Management material before, but it is not real estate specific and I haven't translated it into my own formulas. 

I do when selling appliances- I gotta say, that translator is pretty damn awesome. 

I got out of the D class rentals after I had to explain to a kid that I now owned their house and he was translating it to his mom... so no, I don't have what it takes

I did this recently on a development project and had to give the investor an additional 10% of the ownership in the LLC which translates into more of the cash flow for them but myself and business partner were able to get a loan that far exceeded our net worths and we were able to get the guaranty to burn down to 25% as we hit certain rental income thresholds.

I worked at a senior center, provide social services, I provide translation, and the center advised people to try rentals that don't charge applications fees first, and there's plenty of those, You might collect $100 or so, but delaying a rental for a month or two to get $100.00 is not worth it, IMHO.
