Hey Mark please PM your CPA looking for one to file my taxes have a great bookkeeper so filing should be easy.

There will also be accounting/bookkeeping that will need to be done for the LLC, you may have to pay for that also, as well as a corporate kit.Or You could wing it and try and do it yourself, if you think you know enough to make a good decision without expert help.Good Luck!

Partner #1 funds 100% guarantees loans and handles all the bookkeeping.   

@Carl Rowles Agreed, having separate bank accounts for each property makes your job of bookkeeping that much easier.

And as far as this complicated setup that you have envisioned each of those shells has to have independent bookkeeping, and corporate minutes, some of them will probably require tax returns.

I do have an LLC, and have always done my own taxes, but never official book keeping.

Can someone recommend a VERY simple app or software program for analysis and bookkeeping?

I know it's not specific software for mileage or book keeping but I have 4 properties, have been doing this for 3 years, and just made a simple google sheet to track everything. 

As you scale, if bookkeeping isn't fun for you, consider hiring a bookkeeper for a couple hundred bucks per month.We do 20 out of state Flips/BRRRRs per year and use QuickBooks Online to manage all of our finances for rehabs. 

I've used other programs for it in the past, but I like that Baselane is both a banking and bookkeeping platform built specifically for real estate investors.
