Hi All
I have been looking at  an NRAS property for a client of mine and have produced a cashflow analysis tool in Excel.
In every example i run the NRAS produces a better cashflow than the same property done as a standard investment property.
In and after year 2 is where the NRAS really makes a big difference. One should expect to be up to $100,000 better off with an NRAS property over the 10 year period, not to bad..
OK there are extra cost and rules to consider, yet if you are really in it as an investor ( going to keep it for 10 years or so) as opposed to a speculator then it looks pretty good.I havent had any problems with the lenders I use for my clients getting finance. Mind you there are some banks out there that do not understand NRAS yet  and as such you may not get what you want from them. Still if you know how to present it to the banks   one does not have a problem getting the finance, provided the rest of the customers details are in order.
As with anything do your homework, like most things in life it is not everybodys cup of tea.
