I apologize and I am aware this platform is for RE investments but I know there are a lot agents are on here, so I figured I could reach out on here.

Zillow also pushes their listings to their other platforms, Trulia and Hotpads, so my listings also appear on those sites. 

Easiest to use at least two dedicated checking accounts: one for deposits and the other for the business itself.

With crowdfunding platforms, you can invest little sums of money.

Check out crowdfunding platforms, Groundfloor would be a good option 5-12% return.  

There are also other cost effective marketing platforms available. 

My question is should rehab money come from the same sub-series, or can/does home improvement costs come from the parent LLC or another sub-series that is dedicated to exclusively rehab?

1) Old-school excel spreadsheet and driving-for-dollars/redfin/zillow lookups on the map's property view OR (if you got money to spend) websites like Listsource dotcom2) The city's appraisal district then cross-referencing the address and/or owner's name with facebook, instagram, and google..OR skiptracing services available for cheap on freelance platforms like Fiverr or Upwork

However, I’m open to suggestions.Like most everyone on this platform, I want to build a business that provides me with financial freedom.  

Here is what I would do:  (1) set up a Redfin profile or Zillow or Realtor.com, any of those platforms will work, (2) start looking at property in the place where you plan to buy.
