I am interested in improving my quality of life (socially) by moving to Sacramento.

Due diligence schemes like these have been going on forever its not a new concept the new concept is how avaliable their dupes are to them now using social media IE linkedin Facebook  and BPon another real estate investor website call connected investor.. they actually charge and they do due diligence before they allow you to post.. which they still won't get all the scammers out of the game but it will mitigate it.. 

This is business, not social hour.  

Recently, I've been helping real estate investors with their online marketing, including branding, website design/development, SEO, Social Media, Adwords and more. 

He is older is currently not employed (has some social security income but that's it now). 

I spend 3-5 weeks at the specific house in the summer, (I am a social studies teacher by day) I watch over the renovation project making sure all goes as planed.

If you are computer literate, understand marketing, and the importance of an online presence/social media; you will have no problem being successful.

Do I avoid paying Social Security/Medicare tax if place all my money in the pre-tax option?

They have social security numbers, birthdays, etc on there, so I wouldn't want to get in trouble if the information got into the wrong hands.  

I'm utilizing an RD loan because I'm a social worker who doesn't make very much.
