Its SUCH a big topic, it would be hard to gather all of the data you need in just forum posts. 

My business partners and I are developing a 15 unit residential housing subdivision.We're looking for an excel or google sheets model we can use.We're looking at bringing in investor money in two phases, 1 phase for costs like paying back initial partners, marketing, land clearing, civil engineer, perc tests, etc, and another phase for more heavy duty stuff like purchasing the houses, build roads, install utilities, etc.Who has a model for something like this?

Again this is not an economic crisis or economic recession you can not apply old data point like 2008 and claiming that we are better/worse.

I was starting to put together the data for the fake ads and thought, wouldn't it be better if I had already gotten a deal or at least asked some flippers what their criteria was?

As @Brett Kash mentioned there are areas like that up here.For me, I usually take a peek at the crime data for the area, drive around a bit (maybe have lunch at a restaurant in the area and even ask the servers about it if they live there), then look at rent prices and run the numbers. 

Hi BP, I am a real estate investor in Philadelphia I've been thinking about some ways to get more involved in the market, one of which was getting more familiar with the data that supports house sales. 

I tried my best to read through the posts but keeping how fluid RE market data is, I decided to ask one more time.Please suggest Zip codes and Contacts based on the criteria below.
