I own a business checking account to manage rental income.

Personally I would call your local investment guru agent or property manager and see what you can do.

Whatever you decide will be best for you - BUT - if you do re-finish the floors....MAKE SURE you do the prep & clean work....after sanding - sweep at least twice.....then tack cloth (you can make them yourself - basically a rag with mineral spirits - VERY easy) - I went over the entire floor twice - I might even suggest three times....it gets the "crap" out of the pores of the wood & lets the wood take the stain much better....and the more coats of poly, the better - but take your time - as they ALL have to dry...MAKE SURE they are dry...

Are you going to be managing these properties?

I've been going through "The Multifamily Millionaire:  Volume 2" and in Chapter 13, they talk about property management ranging from 4-6%, on top of on site management that is on the owner's payroll, separate from property management, and that you should budget about 1 staff member for every 40 units.If you (the owner) are already paying a property management firm, why do you have to have on-site management separate from the PM? 

Blaming Loopnet for an allegedly bad property manager is like blaming Zillow for an allegedly bad realtor...I'm sure if Loopnet was stupid enough to give ransom money to BBB, BBB would take down the bad reviews and un-filter any good reviews (which is the entire business model of BBB).

They're managed by a property manager and bring in about $3k per month in cash flow after fees.With a household income of around $600k (pre-tax) and $100k available for investment, I'm aiming to find investment strategies that prioritize cash flow over property appreciation.

The scenario: $295,000 purchase price (my list was $299,000), 100% occupancy, $1,900 monthly rent, with taxes ($1,856), insurance ($768), and property management (7%) the only expenses.  

Partner Driven added value to the Wildwood Drive deal through strategic marketing and quick transaction management.

With respect to the properties you previously purchased, whether you decide to transfer those properties to the LLC is entirely up to you.
