If you plan to scale, i think lower maintenance and lower headache (ergo, newer) is the way to go (for me). 

Turnkeywives.com does not provide property management and you cannot scale, only one unit.

Instead I would prefer to leverage systems I’ve created to scale how much my time is worth.

Some of us want to keep it closer to home, and start at a much smaller scale.. then we build up from there... but if we never start somewhere then we stay stuck in analyze mode. 

If the numbers make sense, multi-family would be a great way to scale faster.

It requires a way to scale to a large number of units as a few hundred dollars of cash flow per unit does not go very far until the unit count is fairly high.  

@Keith McMiller, I have three rentals but I am looking to scale up so I want to be able to assess a property before I put an offer on it.

And I don't see supply catching up anytime soon -- sound off if you don't agree, maybe you see something I don't.I read in some other threads here that the new stuff being built is the newer/nicer and larger scale MF units, and obviously that is going to rent at higher rates, being newer/nicer and all. 

Maybe on a small scale, but in a tight market, buyers are slightly hesitant to give anything away, be it to a colleague, lender, or anyone in between, regardless of the likelihood.

I plan to scale up on buy and holds quickly and work as a buying agent for other investors.
