Although I have not yet purchased my first tax deed property, I have been spending a considerable amount of time researching the tax deed sale process and the tools that can be used to streamline the process as much as possible- one of those tools being PropertyOnion.com.The website seems to provide a wealth of knowledge for pretty much any property you'd like to research, and provides data that could be useful to a variety of RE investors.

I wouldn't be investing in any new city without spending a lot of time on that site first.

If by real estate business you’re implying you have little or no money to invest but are contemplating using one of the guru inspired methods (subject to, “wholesaling” , fix n flip) to create cash flow, I’d encourage you to do research on the true success/failure rate of people who engage in these endeavors, the amount of money the successful operators spend monthly on marketing, and the real time commitment and knowledge and experience necessary for success.  

You will eventually collect unless he has decided he wants to spend the rest of his life on welfare.

It could be he is lodged and charged after which you can take possession based on abandonment/non-payment.It's always a good idea to use an attorney but if you spend the time, read the laws it's a pretty straight forward process to evict on the grounds you stated.  

Spend more than half of your total working hours in an RE business in which you materially participate.2.

Be careful where spending your money over there.

Absolutely I would not spend $$ on a cookbook, not everyone cooks, and it will likely just go in the trash.Also, the first few months are when tenants are in the testing phase, so this isn't the time to show them you are a softy, it's the time to go strictly by the lease, and this is a professional relationship. 

That all goes to tuition, limit dumb spending. 

Social media does not come easy for me so I prefer to spend my time just finding more deals.
