And think about using some of the top notch Milwaukee (or whenever) property managers (many can be found on BP) to handle any rentals you acquire.

I am thinking about doing my first flip to acquire capital.

Suppose my goal is not necessarily cash flow (say I have a full time job that pays around $250-300K a year and I don't plan on leaving it, and this provides enough cash to acquire properties), but rather wealth accumulation -- does it make sense to take the 15 year loan with lower interest so more of the rent payments go towards building equity in the properties?  

My husband and I have a condo as well as duplex, we just acquired, and are trying to add at least one property per year focusing on multi-family in the St.

Probably wise to acquire something that you can afford to hold long-term [EDIT: I just realized that the Deferred Sales Trust I brought up in another comment elsewhere might become a popular option if it survives tax reform and the 1031 doesn't.]

I’m planning to acquire more properties, and I want something that I can scale.

I've acquired one property this way.
