Just some food for thought. 

There are great business forums out there but they are industry specific.Mechanical engineers and fast food franchise owners and medical techs rarely talk to each other or have much in common.Try using www.DogPile.com search engine. 

If you have the extra funds to tie up it can be a decent source of additional income.

Source of FundingI plan to start out with conventional loans.

Many sources, including my LOLO Landlord book, state that you have liability if you discover illegal activities and do nothing about it or you knowingly put an illegal operation there. 

They are a great source of education.

Currently in process of closing on a year and half long short sale proceeding where assistance is needed in locating funding source to provide financials for 31 day period in between A --> B and thereafter --> C closing.Arms Length Affidavit permits for listing to be transferred prior to 30 days and need lien loan provided for duration of ALA.Any/All referrals will be very much appreciated

Just food for thought!

They will become a valuable source to you and your investments.  

Consider this as food for thought and think about how you are affected in your sector of the real estate world by advertisements.
