I took a 401k loan for the downpayment, and at closing, the seller gave me a $25k loan and secured it as a 2nd mortgage. 

What is your favorite solutions for home security if you are a rehabber?

I'm a registered representative with a securities 7 license, so everything i do is done as a security.

Also make sure the security deposit is addressed!

I would be happy to start with 5 to 7, maybe then I can use them as leverage to secure a loan or interests from some investors or partners for future endeavors.

So the choice inside of retirement accounts is "do I invest in securities and get say 8-12 percent with a roller-coaster at times, or real estate where I can get 12-15% with very little volatility"?

So the fact that guidelines are the same makes no difference most not all but most lenders want regular w-2 income. 

Any payment by regular mail are not charged. 

If Bill turns out to be a crazy person and causes major damage that is beyond the security deposit, Jane can go after you for it. 

Keep in mind that the money that you contribute to your Roth IRA does not have to be invested in publicly traded securities;  it can buy real estate and still keep it's tax benefits.
