I wanted to expand on something @Allan C. stated.  

While I only have one LLC right now, I plan to expand to multiple LLCs (one for each property).Here’s where I need your help: How should I set up my account to reflect all the real estate activities like rental income, expenses, and distributions?

Hello Ilya,Where are you looking at purchasing your 1st property.When converting a property from a single family to a multi family, you will need to check on the zoning requirements, depending on your location, not every location has zoning.As far as lending goes, it is far easier to finance a single family up to a quadplex, than financing 5 plus units, the DSCR Market for 5+ units is extremely low right now, and there are few if any lenders in that space.For financing 1-4 units, there are Millions of dollars chasing those loans, so you can easily obtain long term financing, at rates between 5-7%.Please reach out if you have a property identified, and I can help you with financing options.

If you were to read all the comments in the thread you would easily conclude myself and other users of REI Reply did not show up here on Bigger Pockets to "market" REI Reply.

@Michael CsrnkoI recommend finding an accountant who specializes in real estate taxation and tax planning.You may want to consider working with your accountant remotely to expand your options.I would also recommend looking for a accountant willing to work with you throughout the year.

But I don’t see how it can easily be accomplished in QuickBooks. 

If they are professional, they can explain this quickly and easily.

Contractor license numbers are matters of public record and easily looked up on your state’s Contractors State License Board.

This would depend on the location, I know in Texas the RV parks are generating $300/space/month in income, you are easily seeing 30% ROI for RV parks.

Flips can be done pretty easily in 7 days if they are simple and as mentioned with planning or a templated plan 7 days is totally doable even for one that needs a ton of work.That being said 1 day seems unrealistic unless they exclude a massive amount of planning before the project which maybe they are.
