The 99k is what pulled my attention from my goal of acquiring multi families. thank you both again!

My wife is a surgeon and I have helped her build and acquire several locations.  

From 2 small multi's in 2015, to 4 in 2016, to a goal of 8 in 2017 (2 acquired so far) What are the things you need to scale on your list?

Like any other business, there is somewhat of a grind in starting out, but it is a great form of leverage to acquire assets.

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.]

@Noble McKenzie - I've acquired 3 properties via Lease-Option deals; however, I've yet to attempt to sell via this method - although I'm not opposed, and will certainly do so at some point in the future.
