I have a "checkbook control" SDIRA using a LLC so I just enrolled with Simplifile using that LLC and related checking account for payment via ACH. 

I moved into one giant old place and then put an apartment on the third floor using a construction loan that I got at the same time as financing the house.  

Having available credit without using it, or using a small part of it, is a good sign you can manage your money.

Using a FHA loan with 3.5% down and seller assist on 5K of closing costs...I am purchasing a duplex in a "house hack" situation.

Income limits depend on filing statusIf you are self employed consider a self directed 401k as the contribution limits are much higher.If you do end up using an IRA, consider using a ROTH IRA.  

I've been using a Solo 401k [which has check book control] over over 2 years now and love it.My wife & I had two small IRA's that had nearly the same amount as they did 20 years ago sitting in the stock market.I was able to triple them both in less than 9 months doing wholesale and a flip or two.As mentioned above, be sure to weigh the pros and cons of "check book" control.A good resource here on BP is @Dmitriy Fomichenko with Sense Financial.And of course, if you end up in Indy, feel free to reach out to me with any questions!

When talking to a loan officer at a local bank and explaining what I would be doing with the property and she said that I would be using a commercial loan to obtain the property. 

Start prepping the house for quick sale.This is where the creativity comes in to play: figuring out what tool to use for acquisition as well as for disposition, and applying my strengths to the situation;  meeting with sellers directly, not using a Realtor in the middle to mess up our communication; sorting the house into categories that make sense financially for me, as well as for the seller. 

I want to have a name/domain so I can start to form a more official image in the community as a whole.I know that using a last name, and location in the name are rather limiting, so I'm trying to avoid this.Does anyone have any tips as to how they got to their name, and why?

There is certainly a give and take to using a PM.
