questions you need to know the answer to:- what is the amount you want to be earning passively from your investments - what is the desired net yield you want from investments- what areas are you buying in & why (what does the data show on area stats & demographics)- what is your strategy (BRRRR, flip, wholesale etc)- who are the people who will help you get the deals on and close them- what are the risks in your strategy and marketplace and how have you minimised/factored them in?

Zillow and their subsidiaries are trash...mashvisor too...none of these big data firms can explain how they actually arrive at their figures...at least Core Logic has been in the game since the beginning of time and RPR is the direct path to the real estate market as it exists for listed properties, anyway... 

I hate to switch from Mint since it has a couple of years of data on it, but manually entering all of my receipts is a giant pain.

All you do is collect a check whether it's to pay off your debt and keep in your bank account..Some office buildings if it is occupied by one big tenant may have Absolute NNN where the tenant is responsible for tax insurance and maintenance as well as structure and roof membrane of building..I am not too familiar of Office Buildings in terms of force appreciation but Multi family apartments offer that strategy..Hope this helps Good luck

Or does each syndicator have their own method of keeping track of these data points? 

@Robin Dassy the absolute BEST data source that I have seen for ANY state out there is the Texas A&M Real Estate Institute. 

Market cap rates continue to push into the low 5%'s, and I'm seeing new & renovated buildings sell for mid-high 300k's per unit in the right areas.I'm happy to share some market data and offer opinions where I can. 

The Operations LLC is often used for all the highest liability activities, such as property management, paying contractors, collecting rent, etc.This article can explain some of the differences more clearly.

If so be very leary of the completeness of the data. 

I have been collecting my little list of "distressed looking" homes and then Ill get their names and send out letters.
