A prior thread on BiggerPockets suggested using a 20% vacancy rate for offices due to their volatility, but I'm having a hard time making that case to the broker based on the market data available.

Industry was not driven out.

I protest myself with all data i can provide with the recent sales and property condition between comps etc., You gotta to be prepared and bombard them with information.

I am just starting to learn about how to analyze properties and it would be amazing to see some actual data.

@Katherine Sarrettethe deals you are going to find that are going to pay off the best are the ones you find driving neighborhoodsmap you out a area- spend some time looking for the properties that are vacant- they may be foreclosed and not even hit the mls or other investors have seen yetdo a quick search through the county to see what they areset you up a good data base and keep track of neighborhoods and there rents or purchase prices enjoy

However, there is limited data about the rentability for 4 bedrooms, though a local property manager told me 3's and 4's have lower vacancy rates than 2brs.

You can filter the data by zip codes you want to buy in and when the homeowner purchased their home.

My wife and I are strongly considering moving away to a warmer, more tax friendly and most importantly, more opportunity driven market.  

My agent suggested it and back then I had no other data points..  ..and was not even aware of BP. 

I'm scoping out a potential project for an analytics tool for real estate and would love to learn how you gather your data.
