The problem is no one book is going to be detailed enough for your specific state and county.Right here on BP there are lots of discussions about tax liens.

Quote from @Ray Forrest: Hi Hannes,Does Raisemasters provide any sort of templates, guidance or content on building a website for raising capital? 

Do you know of any good websites where I can post my deals?

I find that it's almost a one stop shop in that I can use it for my business checking and savings accounts, bookkeeping, for rent collection, I can issue virtual credit card, I can create all the financial reports I need to run my real estate business and prepare for tax filing and through their partners I can vet my tenants, develop state-specific leases and more.

Another would be you are building other units next door/nearby and you can chalk this build up to the "learning curve".I didn't see a CFO on GLH or GLC's website, but I'm sure you have someone doing this type of financial analysis for your developments?

For example, do you have any specific skills around social media?

While podcasts, books, seminars, and websites offer general knowledge, you'll buy a specific property in a specific location, subject to local rules and regulations.

If your brother is looking to invest in real estate largely from a tax reduction standpoint they should pay a qualified real estate tax strategist to review their specific situation and what may or may not work for them. 

One thing you might think of doing is having and promoting your own website to avoid the exhorbitant fees charged by the third party sites such as Expedia, Booking.com and Air BnB.  

Are there specific national or regional agencies that coordinate temporary housing for disaster victims?
