Keep in mind that your commitment should be to hold this property for 3-5 years at a minimum. 

Why not just hold the property forever?

I'm holding out for Idaho though, unless something remarkable pops up that I can't refuse.

Also, accounting for flip is different from buy & hold or wholesale, so make sure your process and procedures are set up properly. 

Are their certain broker holding companies that deal with these types of situations? 

It shouldn't be driven by number of properties (unless commercial) but rather how much equity each LLC can hold before creating a new one.

Do clients with 'regular' accountants now retain 2 accountants or switch regular accounting to the specialized accountant(under one roof)? 

The advice I've been given, and chosen to follow, is to utilize HELOCs for short-term investments, with a plan to pay them off in less than a year and to avoid holding them long-term.Do you know what the value of your recent rental property purchase is?  

My goal is to start with a solid foundation, and I would prefer to hold this property for the long term, making enhancements as needed.This property is in an area with many homes built around 1900.

I have a decent amount of equity in my house, as well as family members interested in flipping with me, with a very large amount of equity they would be willing to use.I also am interested in rentals, whether single family or multi family, interested in both STR/MTR, as well as regular rentals.
