You will get a lot of plugs for Mark on here and in my experience they are well deserved.
He is focused on the Hamilton Investor market, and extremely motivated to make deals happen. Both the buy and importantly the sell. Mark also has a "calming" influence and does not torture himself or you if a deal doesn't go through.
He has made me quite a bit of money despite some of my stupid mistakes.
Good luck.
And last but not least, using Mark is the easy part, it's the ongoing Property Management in a challenging market that you will really need to nail!
