It's not your job to run around telling every female in the world that he may be dangerous.

What advice would you give for a single female just starting out ?

Tell the female that her boyfriend is not allowed to live there and if she doesn't get rid of him, you'll evict both of them.

Have anyone had experience renting by the room and mix males and females?

@Cory SparksHey Cory,Maybe look to find a property that needs some work and you can force appreciation buy doing some rehab work yourself with your partner. 2 female friends of mine were able to find a distressed pre foreclosure, get and FHA loan, learn and tackle most of the renovations themselves and then rent out 2 units and live in the basement unit themselves.

An ugly, dark kitchen will turn off females, but sometimes a coat of semigloss paint on cabinets will do wonders.

Now that you mention it there was an account with a female name (I forget what it was) that was trolling people and talking all sorts of **** about Vegas a couple of weeks ago that I haven't seen on here since. 

NONE of the female engineers would live in either of the nearby towns...

The only one I know in this area (or near ) is West palm beach they get together once a month or so and there is one here in Fort Lauderdale that the post constantly here in this platform, ( but is for females). 

As a female she is going to want a certain "class" of roommates so she feels the most comfortable in her own home.
