And they had stashed the stolen objects on your property, and then name dropped you to the police.  

Both were profitable but it wasn't the prettiest method...I am currently debt free loan free and have $40,000 of investment capital stashed away and about $10,000 to live on as I am a single 30yo male living in a 2 bedroom apt paying $1200 for rent and utilities Have a job that pays roughly $3,500 a month on average.

You have no idea of the value of the items inside; we have seen cases in which individuals lived like absolute paupers but had personal property of very high value stashed in the apartment upon death.

We've got close to 6 figures stashed (liquid) and in some markets that's enough to not need to raise additional capital for an entire deal.

Be sensible and pragmatic about it though, in that your preparations shouldn't put you in a bad spot long term if a downturn does NOT come (e.g. stashing cash under your mattress).

Meanwhile I own a stash of rental properties that ALL of my tenants are 40+ years old.

In the last 3 years I was working and stashing cash so up in savings.

That first year allows me to stash away some nice capex money for the future repairs. 

Once you have a stash of cash you can begin to think about investing.

Long story short, grandma had been stashing cash in the place for about 20 years.
