Sometimes people who behave like there is something to hide actually have something to hide.

They should know and behave as if they do what you say, not the other way around.You got smacked for involvement, and I'm so very sorry that it happened to you.

There's nothing you can do to improve how the stock market behaves).Cons:Requires effort (stock market, you just buy some mutual funds on the web and then there's nothing else to do)Follow the IRS rules regarding prohibited transactions (when investing in the stock market, you have no opportunity to violate those rules). 

It is really upsetting to see military personnel behave this way.

Location:  What type of tenants are you going to be having there? 

I know it behaves like a condo is some matters

You are likely doing him a favor in the long run by not enabling this childishness and showing him that this is not how adults behave.

Given that I will be considered self-employed and will initially not have income (or at least not income that is steady or predictable), I will be having my parents co-sign the FHA loan to fulfill the income requirements.I clearly have sufficient capital to not only fund a 3.5% down investment, but to also make the subsequent mortgage payments.

Tenant is around 27 yrs old and will be having his mom co-sign.Thanks in advance for your help.Best,Matt

Editing to add we are a little more worried than usual (we would probably just run fans and a humidifier and clean up ourselves) but our forced hot air system comes from this basement and we have a newborn baby so really don’t want to be having mold coming through our air vents!
