I joined biggerpockets a few months ago and have been studying a great deal to prepare for my first REI.  

My credit is also fair, so that is not good, but it is also not bad. 

Just trying to learn, will an irrevocable statement (mixing another language like an Irrevocable Standby Letter of Credit / Irrevocable SBLC) or something similar of an instrument where both parties cannot take back what is in writing UNLESS another instrument is provided before the original is due.

This way you can help them out of a bad situation and possibly help them save their credit by avoding forclosure3.

I think I would be lucky to qualify for a loan of half the amount of what I estimate the property to be worth.So as of now I'm saving (5k now), keeping my credit score in the "excellent" range and trying to learn new ways to fund my first investment even if it isn't purchasing the multiplex I live in now. 

There is nothing a CPA can do that an EA can't except for provide you audited financial statements (the person preparing them cannot audit them anyway).  

Hello,In the next month I will be closing on a property in Baltimore which I would like to do a historic renovation/CHAP tax credit.

Besides that, some just want the quick fast money, no application, no credit check, etc. 

Was your credit score an obstacle in any way shape/form?

There are creative ways around it, but you'd need to have good credit and income.
