My hunch about a drop comes from the fact that the last 3 downturns resulted in 10-27% drops in housing values (see data).

There's no need to guess, the data is available. 3) Rents - I've been looking on Craigslist and Trulia, etc. for comps on what I can get for rent. 

If anyone has quality economic data on the Southern Oregon area, please share link or info!

Land is hard to comp using the mls because sometimes you do not have enough data for an area.

So, if your data is in row 1, cells A through E you might want F1 to be: =a1 & " " & b1 & " " & c1 & ", " & d1 & " " e1You can use concatenate, but you still may have to include spaces and puncturation to get the desired result.

Software like Argus and/or customized spreadsheets can given you precise data if you feel like your crystal ball is better than the next investors' ball.

Ideally, you'd want to be armed with some data before you call them (perhaps what other apartment buildings in your area are being charged per dumpster, per pickup).

Put stock in actual sale data and not their Z-estimates.

They go on to say that the data is collected from public or user submitted data, real estate agents, appraiser physical inspect of the home.

What is your tolerance and where do you go for data?
