Business Credit
I have a homebased business I am considering Inc. to form S Corp. I have heard that I may be able to use this credit to purchase a mortgage , car ect...w/o using personal credit. Anyone know if this is true, and how hard would it be to accomplish. 
You may eventually be able to use the credit of an C-corp to purchase without your personal credit involved, but you will have to build the credit of the entity to the point it can support itself.
S-corps and LLC's in my LIMITED experience almost ALWAYS require the personal guarantee of someone and their credit.
Your entity will also need to be able to support the payments of a property purchase on its own if you want it to qualify on it own. Any lender will also want some history on the company, so if you are just forming it, I would say you are a couple years away at best and will probably need to personally guarantee some of the earlier loans to get the credit rolling.
Greetings,
I know a little about this subject.
Hopefully your homebase business is successful.
Once you file for the S-Corp EIN.
Use the EIN number in your local shops such as gettng accounts with Staples, Office Depot, Home Depot, etc.
They generally require you be in business over two years not to have to sign your name personally as guarantor.
Then call Dun and Bradstreet and ask for an interview.
They will call you back and ask all the pertanent info about
you and your business.
Once you show you are successful in business and pay ALL your debts ON TIME you shouldn't have too much difficulty from there.
I suggest you talk to a mortgage broker about real estate in the corporations name to see what is required.
That's a start.
Good Luck.

And of course this is not to be construed as legal advice.
And of course you should talk to other professionals about this as well. I assume the use of corporate credit is separate your business from your personal life. There are benefits of doing this. But you must do it right.
