Different colors for each product.As previous mentioned, mold is everywhere (please come look at my bath tub for a nice growth currently...it's mildew).  

I get to work with active investors to help them fund deals, I don't get phone calls at 2am to fix thing, I don't have to pick out paint or carpet colors, it's just easy.

Try to go with a different (neutral) colored paint on the walls and have it be a color that will look connected to the green wall tile and the floor tile that you will install.

They have great paints, consistent colors and consistent bases and can mix up pretty much any color from another manufacturer.

The cost of doing this is negligible at best and is not a large expense for the broker, compared to the whopping commission they get from the sale of just one home.And please, don't tell me about the cost of color copies for Open House flyers and the like.

Talks about the psychology of negotiating (you may be familiar with it.)

The color of the walls? 

If I don't a particular agent because of skin color, sexual orientation, or whatever, I may decide to offer them less. 

I do wonder if I leads to more inventory though, I have for instance another client that this 2.5% might be the difference in deciding to list or not, for sellers without a lot of equity that 2.5% can be the difference between writing and check or not, which in addition to some people not having the money to cut a check is also a huge psychological barrier, there are probably even some people on the margins who have in thier head they will only sell if they can net 100k in profit or some random number like that.

you are kind of dealing with three diffrent issues here, the thing about not being a legal three unit, super easy don't buy something that's not legal, and your agent really shouldn't be encouring you to break the law, the issues with properties being beat up, the vast majority of multi unit's that sell have some wear & tear that's often the reason for selling, being a tired landlord, if you want turn key, you are proably looking more single family homes or paying big dollars for a turn key multi if it even exists in your market, 3rd we can debate the pro's or con's of this this market but youve hired and agent and 99% of agents are going to tell you its a great time to buy, i'm usually more measured but that's because I have a deep psychological problem in which I care more about being intellectually honest than making money, most agent's however are not afflicted with this disease so your gonna have to make this decision for yourself before you hire any agent.
