Yes I would ask for lic number and proof that plumber is bonded.

Plus, I would never spend 200k on a single bond, obviously, so it is daunting/ irresponsible to imagine doing that on a property at this time. 

just need to send 5k to a bond company in Thailand  ...

Government and quality corporate bonds, and gold are all traditional hedges against recession, however not specific to housing.

I just wanted a career that can strengthen my skills in the real estate market while also earning a high income.

Have a good stash of cash (not stocks, not bonds) to do deals if the banks are not lending and the market is crashing. 

Governments many now require bonds from developers.

I thought that using a self directed account to invest in RE is actually the same as investing in stocks and bonds but I spoke with one SD custodian and he made it sound like the disbursements (for lack of a better word) from a self directed account is still actually just considered a loan and therefore still has to adhere to those regulations.If anyone can give some clarity on the subject I'd be very grateful.Ben

He is licensed, bonded and insured.

Any investment suggestions with that amount for low risk and medium returns other than CDs,Treasury bonds etc?
