Once you have a shortlist, sign up for an account with each one and test them extensively to see how they function.

I recall a specific framework of business start up along the lines of starting with yourself, then adding an Admin, then an Ops, and then other support functions after that. 

When my accountant was with H&R Block they functioned this way and even though he could prepare my return in about 1.25 hours it would cost me $1800 because of the number of inputs I had specifically from my 7 properties.

Unlike a cash-out refinance, you pay for the funds as you go and it functions as a credit card (rather than a mortgage), giving you more flexibility over the funds secured via your house and is potentially cheaper than a mortgage since it is not amortized.

I like the mechanics garage one could also take massive cost seg on all that equipment.. and same could be done with doctors office.. i did that with a dermatologist a few years back and it has worked out great helped young doc walk right into a functioning practice without her having to go borrow hundreds of thousands to outfit a shell..

From a bookkeeping standpoint, this makes everything a lot easier as long as each financial account is used the way it is supposed to be used (no commingling).I would just caution you to think about the functionality of that structure within your day-to-day business operations before pulling the trigger on it.Make sure you're keeping things as simple and efficient as possible.

At the end of the day, the legal arrangement has changed, but the functional arrangement is basically the same.
