Can any of experienced fellow REIs kindly teach me what activities I need to do to avoid those risks?

lots of resources here,  one local guy on here i know is active with oil and gas and might be a good resource for you on that end. 

Do you have the funds to take down the deal or this a just for fun activity that is for your personal edification with the hope that one day the money will be there? 

Preferably as many units as possible but with hidden value in making improvements (the unfinished attic in our current house was a goldmine) a.My feeling is auctions are good place to go for this but I don’t know anything about auctions. 3.Rent a property to live in for the first year I can’t subject my fiancé to living in a gut rehab again 4.Use the cash generated from the property and work during that first year to put together a down payment for a house for us. 5.Re finance the rental property and buy more property.These are my other day one questions: 1.I’m an architect, does anyone have any advice for actively leveraging my skills to help me do this real estate investing thing full time/ what career change could help me ease into this while still having a salary?

You can very inexpensively have watermarks added to your pictures that will help deter this activity. 

Have a great weekend!

I am currently an active duty Marine stationed at Camp Pendleton, living out in Oceanside, CA.

Hi @Jeff Moore,That depends a whole lot more on market and activity than a general statement ...

While not at work I can be found running in the Oakland hills or actively racing in various trail runs around the bay area.

However, I had contingency plans in place to report him if it ever came to that.After he moved away, my neighbors told me the person who sold me the house was worried this guy would scare me off and had the mail order minister scale back his activities until after I moved in.
