No rush there the values as any of the folks that work those will tell you they just pretty much stay neutral.. its were the term I buy for cash flow I don't expect appreciation comes from. because that is exactly what happens there. 

I like the orange smell, but there are lemon odors, neutral deodorizers (like the new car smell).

Ozone works by chemically neutralizing he odor molecules.

It works wonders to hang smokey clothing over a pan of white vinegar to neutralize the odor and make them smell fresh again.  

Be happy the home is cash flow neutral.  

A neutral tan like Sherwin Williams Kilim Beige works well. 

In high value easy to manage markets... neutral to even cash flow or even negative cash flow on certain properties is fine... let the tenant pay off your A grade property.... what folks usually don't understand until they try to sell .. the lower end rentals have an extremely thin market especially when you own 100 of them or more and want to sell them all at once.. investors back into the numbers and most times what you think thye are worth and what they will actually fetch is two huge different numbers.

Buy what's inexpensive and common in your area but plant it well and after watering it for the first couple of months,  it'll be low maintenance but look classy.But if nothing else, paint a nice neutral colour, create a more substantial entrance, and put a pot with low maintenance plant/s on either side of door.  

Keep colour neutral (beige, white or grey to continue the theme of the rest of the house - which should also be all in the same colour family).

The original floor was asbestos (likely) vinyl tile so need to get that covered and the floor is not level enough for real tile. this is not the tile we used, but it's similar (darker): Sannita Neutral 12 in. x 24 in.
