A place in rough shape should rent lower than a place that is highly polished.

For example, one I've done is on things like rebar and steel plates in the slab.Honestly the bottle-neck is my desire for them all to be fairly polished.

Will get other bids and see if we can polish up the turd...

I have purchased and read a few books on investing but I need a little more polishing on the math behind real estate.

Am I trying to polish a turd?

So, calling it polish instead of rehab. 

Polished diamond plate aluminum for a garage as wainscoting.

want a polished professional looking site with out breaking the bank .  

Do not listen to people telling you "dont rent", listen to your "Polish" heart, dont be cold hearted like many people who are only for $$ in this world, and ask yourself this, would you rent to people with no credit history nor social security?

I do have one polish friend, who hasn't stopped working 100 hour weeks for the past 3 years and at 28 he is probably almost at that goal, and he said it's been miserable.
