I am looking to purchase my first investment property in the next 6 months but in NZ to get my toes wet.I'm looking for buy to let properties that will have great cash flow and also be able to recycle my deposit to continue to purchase more and more. 

That they didn't leave a gallon of milk in the refrigerator?

I don't want to see you on the back of a milk carton.

well its simple math really.in many markets there simply are not enough homes to keep up with the population and the values of existing homes makes it near impossible to build new with what every thing cost to build new homes in many markets.. so you take out new construction .. like in many markets hardly any has been built in 10 years.. recycle the old homes.. and population goes up .. you have the markets you have now.you go to parts of the mid west that have seen steady population decline over the last 20 years and markets are flat as a pancake on values and no new construction but still plenty of homes to go around since people are fleeing not coming.. for instance in Portlandia 80 people each and every day move here from somewhere.so that's my take on it.also as investor don't we want are properties to go up? 

Looking back I'm extremely happy I did, now I'm in a better position than I had ever imagined.As mentioned previously, it takes two RE cycles to become a multi-millionaire.

Use them when you evaluate stocks and bonds, not REI...particularly if your end game is cash flow...as it should be.When was the last time you walked into the grocery store and for a gallon of 2% milk with 2% of your cash flow.  

While vacant an enterprising neighbor decided to recycle the siding.

Milk, kitty kitty...Of course you can't advertise or verbalize that you want to rent to an older couple, but you can think of attributes that older people are more likely to have that you are interested in.  

They many times are recycled test questions so It can help prepare you!    

It also helps to have an unbiased building/energy consultant (ahem, like me) rather than individual HVAC installers or contractors (who are trying to milk as much $ from you as possible) to help prioritize energy renovations.
