Also the land in question, which I have not purchased yet has this in the listing "All offers must be accompanied with the addendum provided in Trend."  

Your agent can also tell you what is going on in the market and help you know market time, average selling price, and what the trend is.

I can't speak for NYC but in Philadelphia area we use TREND MLS and unlicensed assistants can have MLS access for a yearly fee.

Don't know how far into the deal you are, but also verify (if you haven't done so already) the vacancy of the entire complex and HOA fee trend.

@Matthew Hudson did you check the market trend?

The house I am building is trending toward the higher end so a comparable traditional system would have to be something along the lines of a energy efficient Trane system rather then a run of the mill package unit.

This has been a growing trend that nets healthier returns for PM's like myself and a higher quality "tenant" for landlords.

Understand the path of progress via job growth (look at 5 year trends), business development (through biz journals, chamber of commerce, etc), know if market is owner friendly versus tenant friendly, and talk to property managers in the sub-market to understand rentability (is a PM confident in their ability to rent out a unit and quickly).

Hi,I live in WA state and was wondering where I would go to look at employment, income and population trends across the country.  

Since this is becoming a trend for these homes, I have suggested the cheaper composite wood flooring as it is much easier to clean.
