I get that Quicken is supposed to be for personal and Qucikbooks for business, but when it comes to real estate specifically, Quicken has a tailored product whereas Quickbooks does not appear to. 

You are comparing two different products.

Here's why I think maybe keep them: They have character and may add character to the finished product.

Schools, in my opinion, drive demand and shape demographics, which will always keep a steady supply of renters / buyers available for my product, even 25 years down the road.

I currently work full-time in a product marketing position for large agricultural equipment.My short term goal is to flip 1-2 houses in the Cedar Rapids area.

The end result, the people that rented, rented it prior to seeing the finished product and loved it.

I am impressed by the people that are included on the list of Brian's students.As a side note, I did meet one of these students last weekend at the Texas Expo and have to admit that I invested in a product of not what I consider to be another "shiny object," but just good value for the money in an area I felt I needed to know more about in my education.

Also important to insure each entity for "products/complete operations" of 2mil min, and aggregate 2 mil min.

One that I have looked at (I have not used nor do I have any connection with) is AmeriSave Once you put in your numbers, it will then give a list of their mortgage products with closing cost estimates.  

Secondly, if you're concerned about separating yourself from your business as much as possible (per having an LLC) then doesn't it seem very counter productive to use a HELOC on your personal home?
