Section 8 vouchers are always in demand in a locality, and therefore rentals that accept them always are, to a degree.

One day I stopped and decided to focus on all the money I put into a college degree and started a career in graphic design, while also continuing any type of side work I could get my hands on for extra cash.

I look at it like a college degree even if you don't apply to your field of study you will still have a leg up majority of the time in all fields against those who have no proof of continued education.

(Pay to) go to school, finish years for your degree, get job with that degree (God willing), work your job with that degree to earn money to pay back debt, don't obtain your full income because a percentage of it is going to go to paying off the debt you acquired to go to school, and don't move up unless you're willing to pay for more schooling.

I tell those getting into commercial leasing that they really need to understand the business of the tenant, to some degree, the bigger they are, such as Wal-Mart the less you really need to know as to the details, but a small operation, mom and pop under a franchise needs more attention, it goes to the sophistication of management.The major retailer moving in next door, is this a complementary business or more competitive, having an Allied Paint store and having Lowes move in next door, so that issue needs to be clarified.
