I highly suggest you stick to the tried and true - white appliances and neutral colors. 

Get the neutral ones, and tell us what you use.

Anything neutral is good. 

I would repaint the dark rooms a light color like in the other rooms with the lighter, neutral colors.It's a really nice place. 

If your buying stand alone rentals in non appreciating markets or markets that historically move very little then positive cash flow is the only reason to do it in the first place.If you buy in markets that history of strong upward movement then neutral cash flow or a little negative is fine in my book..

Are the room colors neutral?

I also eliminated some old incorrectly grounded/neutral bar sub-panels. 

Anything neutral, like tans and creams...basic white ceilings.

For this very reason I think the last place anyone who lives in a high state income tax like CA and Oregon ( close second) should buy rentals Is Texas... you need to live in Texas to make sense of buy and hold in that state.. to pay income tax and what amounts to 2X to 3X amount of property tax just to hold a rental is I think something that many just don't look at .I can't tell you all the folks I talk to that go into Texas buy and hold don't realize what the tax's can do and after a few assessments their positive cash flow is now neutral or negative.. and in foundation issues Hail wind etc.. tough place for out of state to do business.

Purchase at 80% LTV cash neutral non-commercial residential, in 5 years have 50% appreciation (less than 10% annual and less than many markets have done in the last 5 years).
