These vary in size and do not need to be cash but can be an IRA or stocks and bonds.

I feel slightly uncomfortable renting rooms to tenants who don't know each other (and don't share any common bonds as college students may have) and I'm wondering whether or not I should begin to ask tenants to vacate in a slow drip in order for me to renovate and put up for rent again where the tenant will have to pay the full amount for the unit as opposed to the room (and leaving me with vacancies).

Bonds?

The city has already approved bonds and other spending for infrastructure to prepare for the rapid growth.There will be tremendous need for low-cost housing since many of the employees in the villages are in the service industry.

Stuart, I would put a majority in different mutual funds and bonds that get a return better than 4% which would give you 100k a year.

LOL So now each of my LLC's that has a different project has to have the developers license. its a pain there is no test but its a bond and insurance and not every one can get bonded these days.I know having done a lot of work in Chicago how tough that city can be as well.. no one is going to teach you this you just kind of learn it.so bottom line unless this person has some very narrow niche // or its just a raw raw thing to motivate you  chances are there is nothing unique and I am not talking about getting rich with tax overages or some of the other things that get recirculated constantly. 

Even with a historically high stock market the bubble is in bonds.

As a general contractor, we also make sure that the subs are licensed, bonded and insured.

In the meantime I plan on getting my real estate license and apprenticing under a local investor in order to further expand and strengthen my foundation.

Some editing could strengthen and less is more.
