Start their own consultancy (either recruiting agency since they are the top recruiter like I did, or if they were pentesting for different clients like banks, fortune 500, etc, they start their own pentesting consultancy/firm).

Nomad also held the renter's deposit hostage even after I cleared the transfer with no damages to be charged.I had to remind Nomad there is a difference between “can” and should” , while you “can” hold a deposit longer it “should” only be done when there is a question about damages.My bank liked the guarantee, the disorganization inside Nomad and the horrible vendor management would cause me not to use them again.

It earns a great rate of return compared to a bank account and is fairly liquid.

Shop around for debt to see what is available and model the various structures to see how the different terms impact performance.The tradeoffs will be fixed vs. floating rate, conventional vs bridge vs CMBS vs bank vs agency.
