I have a solid W-2 Job making around $55,000 including incentives and a credit score in the 760-780 range, I have no debt other than subsidized student loans of $12k in which I won't need to pay interest on until 6 months after I am out of college (over a year from now). 

Last year I raised $50 million in a fund forecasting IRRs in the 12%-14% range.  

Looking for recommendations on gas vs. electric vs coils range.

There is also newer solid state battery technology that promises higher range and 5 minute recharge.

We have 3 2/1 houses in Omaha, that range from $1050-$1350 and those do not have garages. 

What could spook the housing market to fall further than that, to the 10-15% range (maybe 20%), is if the stock market starts a major dip at the same time.

The answer is very different for a multi family due to state wide rent control.You have the notice duration correct when tenant is on a month to month lease and has lived in the unit over a year.  

@Mark Baldwin my wife and I house hack here in San Diego and it won’t run you into that range.

All of this will generate a different profit margin and cash flow for each range in any given nicro-market

The range of recommended percentages are 5-15% for repairs, 3-10% for vacancy, 5-15% for CapEx, and 7-12% for management.
