which sector is most suitable for foreign investors willing to buy in CASH (Single Family,Multy-Family,Class A,B,C ,etc)Thanks in advance.

I provide property management services for the residential sector in the North Atlanta Area. 

From my perspective just in general patch of land is focused on RE and has built up some knowledge of the RE sector where as far as I know Lending up is much more broad and focused on lending in general.

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

After a slow start I'm ready to kick up my investing. main goal is more education right now in the multi family/apartment sector 

Blindsided by the financial technology sector that has produced successes like PayPal, big banks are struggling to keep up the pace.

Though the commercial-real-estate sector has a reputation for being slow to embrace new technology, several brokers and developers are hot on virtual-reality tours—to boost leasing and sales, especially to technology firms and tech-driven media and advertising companies: http://www.wsj.com/articles/the-office-space-in-your-head-1435541344

This isn't a growing area, but is close to a ton of jobs in the industrial sector. 

And should there be any slowing down of the single family market, commercial assets, particularly in sectors such as multifamily, self storage, and mobile home parks, tend to be less correlated to the market sentiment, thereby further insulating investors from market downturns.

I like the idea investing in a sector I am not big enough for but getting the returns much more like "mailbox money" than my other investments (less headache it seems)Here to see what everyones experience has been?
