Simon, Here in FL its much easier for us because we know a few things:1) The U.S. is severely under supplied in housing units. 2) Tons of people are moving to Florida everyday which makes point #1 even more drastic for us. 3) Interest rates are preventing people from selling their homes, because then they would need to re-trade for a higher interest rate buying a new home, which is creating even more housing demand.So with this knowledge, now we move to more market specific data, which is what I talk about in the original post.If a market shows decent growth and demand, then it all boils down to the numbers.Its important not to forget about any costs though.
