Beyond that, you can swap out the toilet, vanity, and light fixtures (if they are simple). 

While reading about the Buy Rehab Rent Refinance Repeat strategy, I come across  the following questions and maybe that someone experienced here might shed some light.

Garret Morgan (inventor of the traffic light). 

Is light gray still in for wall color.

At least I didn't suggest putting a red light on the porch!

The red blotch on the lower left tile was the lighting not a defect. 

Or any other light neutral color (blue, grey, etc.).

How tall and wide the house is makes a difference and how much support it needs underneath to move in the first place.If you have to go across old bridges with weight limits, around a bunch of tight curves, low power lines and traffic lights that have to be lifted, street trees you have to work around etc.Distance and what time of day due to congestion house would need to be moved.10k to 30k sounds very light to me on moving costs.

I would get some black and white electrical tape and flag each wire for someone else's future use at a minimum, the same way you flag neutral wires being used as hot in light switches.

Prebuilt cabinets, lighting, granite, lumber, vanities, appliances, sinks and faucets, doors, paint, etc. where are you all buying from for your flips/rentals?
