You could easily just pick a simple well rated dividend stock, and put that $ in, turn on auto reinvestment drip, and in 10 years early, pay off the remaining mortgage balance in full AND still have a considerable holding in that stock account to boot. 

if you rent and are a landlord you need landlord insurance. if you own and occupy you need homeowner insurance. if you rent and occupy you need renter insurance. if you own a motorcycle you need motorcycle insurance. if you own a car, you need auto insurance. if you own a boat, you need a marine boat owner's policy :)

If it were on excel, it would be great if it had auto-calcs that could be updated every month or quarter as cash accumulated and debt was paid down.

For example, I was looking at a house a couple of weeks ago in a subdivision with no HOA and saw that the residents at one property were essentially operating an auto repair service out of their garage.

We have systems in place for everything, we have a texting system that auto logs communication to their tenant file, cameras in our facility that record video and audio, our phones are recorded, emails auto link, there is nothing for tenants to say when we have a mountain of data and all notices recorded in the system.  

In the event they someday win a judgement (let's say they're in a car accident and receive $10,000 from an insurance company) or someday sell a home (perhaps a parent willed it to them) you (and anyone else who has a lien against them) will be first in line to receive your owed money

However, insurance is limited because it only protects you from one type of liability: accidents/negligence.

Send me a message and we can get you set up on an auto search so you can see all the properties as soon as they hit the market.

Ask anyone in Detroit about the cultural significance of the Motown Era when Detroit was hopping with the Auto industry.

He never did pay for the car (it was a cheap island beater, that didn't bother me much, it was better that he was finally gone) and the great part about that was about 4 months later I get a call from a debt collector asking for a significant amount of money due to an accident the vehicle was involved in without insurance or valid registration (he never got the title transferred!).
