I think that any inanimate object can be considered that way, but the Earth is a living amazing thing that we as humans are still learning much about.

@Patrick Ruff I know what it is like to burn the candle at both ends.

So, if you say that's your reason for turning them down, I don't see how you can be sued for discrimination.Google protected classes and discrimination and you should quickly find that you aren't violating any discrimination law, even in SF for this reason, as long as you are consistent and can prove that this was a pre-existing qualification.Now, if they all turned out to be from a protected class (all African Americans, for instance) and you have never used this reason before for turning someone down, it will certainly look suspicious.And really, why on earth is it your problem how your tenants deal with sharing a bathroom? 

If you burn the candle at both ends for as long as you can and establish to yourself that you can bring in as much if not more money in investing over a consistent long period of time, you won't even have to debate the move .  

For now, I enjoy the frequent visits to the family and buy scented beach candles that don't come close to comparing to the real thing.

I burned the candle at both ends until real estate investing took over financially and it was clear.  

I would work 7 days a week (as an agent you don't get off on the weekends) and were burning the candle on both ends running from meetings to job sites and back.So my goal for this year is to log a little less hours, lower my stress level a bit and make more time for the things I enjoy outside of work.

Look, I can find articles on end that clearly state that Earth is flat.

The earth is 4.5 billion years old, but we are a young species, relatively speaking, with an average individual allotment of three score years and ten.

I get the location of the park, and with google earth I know more about it in 60 seconds than most people will in a full walk through.
