I would recommend keeping all of the data in one sheet and using filters to narrow down. 

I have some data that I would like to share with you.

ACTUAL data is always best. 

You can do any strategy you want personally so long as the market data supports a 1:1 under STR, MTR, or LTR income strategies.

Allow me to explain something to you.What people call "chest pumping" simply is proving others that are wrong with concrete data showing them they are wrong and why, so they can learn and grow from it.

Even with 200 STRs it isn't a broad enough cross section to assume the changes.You would need to have millions of data points to show the trend IMHO. 

You should estimate th property value using recent sales data.

Don't worry about minor complaints, you are doing a fine job.Just one question, ALL sites have a delay in data from MLS updates, and from court reported information, and so on, is that a function of a monthly update routine or can the information be updated a little more frequently? 

Explore my personal favorites, Set For Life by Scott Trench or The Total Money Makeover by Dave Ramsey, for invaluable financial insights.3.

Don't base it on one data point that is not available :) good luck
