For a 4-plex, you can potentially sell to an owner-occupant as well (as you are doing), but chances are good that a pure investor will purchase your property when you go to sell.

Additionally, it's not likely to be a property you can transition to a good rental down the line due to cost and restrictions many condo boards have on leasing out units.Duplexes can sometimes work for owner-occupier, but if you decide to turn it into a pure investment the numbers may not work out very well.

@Syed Shah for rental property I like the common area walls to be painted "pure white" from Sherwin Williams and bedroom walls "colonnade gray." 

In addition we buy pure rentals on the side.

I'm purely guessing, but there could be an uptick in TV and film people flocking to Atlanta because of the all the work it provides, and who might be looking for short term rental units to stay in.A lot of my production work deals in neighborhoods with high crime rates, so at least I'm learning where NOT to purchase!

As we have built are careers up we save one income and invest the other into pure rentals.

If it is purely investment for new zealand then Auckland or Hamilton would be better growth wise.  

If you do NOT want to live in this property, and it is a pure investment, you will in most cases need to put down 20%.  

We invest through two methods, pure rentals, and personals turned rentals.

A sub S is generally better for flipping while most favor an LLC for pure renting.
