So if you discount a small amount to get rolling, that is something that can work, but don't want to stay low for long.You will start to get the dregs staying at your place and they can do some real damage to the place.

Install low flow water heads, swap the washer/dryer with High Efficiency models, replace the water heater with a tankless version and lock the temperature at a reasonable level, install smart thermostats that will automatically reduce the heat/cool when it senses no one is home, swap all the lights for LEDs, etc. 

Low risk investments sell at a premium, that's the whole idea of cap rates.

I would tell people today that if you buy a primary residence expect to stay in that home for atleast five years, especially with a FHA loan which has lower down payment as the current forecasts for home appreciation or very low which with closing costs on the buy and sell, it will take several years to have equity in the property and enough to be able to sell, so that is something also to consider.

However, the rental value this area is very low compared to the Home values and mortgage rate.

Rates that low don't make sense especially if they're a no doc shop.

Honestly, I think you're estimated expenses are a bit low.

Flip side, for a third of that you are trained to find properties using creative finance taking over existing low interest loans that cash flow and you are buying in decent neighborhoods with every day lunch box Joes that have kids and go to work and pay rent on time. 

if they are a great PM 20% is totally fair. not too high and not too low

I got a nice reduction by the way, since I was able to clearly explain what was going on.
