I think, as much as anything, you've got to study the micro-markets concentrated within your target market.

Not ready to build, but want this dirt work done while its dry in the fall, and will let the ground settle over winter with a freeze/thaw cycle.My metal building contractor called and said the manufacturer is no longer going to do Metal buildings, they are going to concentrate on their grain handling side of the business. 

If your goal is to generate passive income, you'll concentrate on properties with good rental potential.

I know of a few off-market deals there and it has a high concentration of small multis (duplexes, triplexes, quads, even seen several 8-plexes).  

There are some serious monsters or concentration of them in the 48204 and 48206 zip codes like on Calvert St, Tuxedo St, Lasalle, etc.

Hospitality is a people business, the concentration of management is optimal and eliminates the zoning or permitting restrictions.

Where are you at now - concentrating on THE DEAL or on building a PORTFOLIO?  

A lot of people are concentrating on sourcing these type of deals.

Some look at credit cards for the score, others concentrate on mortgages and bills,

You really want to concentrate on Worcester.
