I had someone interested in buying a multi-unit building...it leading me to brain storm. 

Would love to get leads on anything you have.

The big value-add for SEO firms is not industry knowledge but an understanding of how to build SEO models and do analysis with data that is collected as you go.AdWords is another strategy that tends to generate quicker turnaround (but at a higher cost per click).

Additionally, these factors create more inefficiency in the market which leads to greater opportunities to find value.  

It's not enough to know that over the next 5 years, your purchase of an investment is likely to generate say, one and a half million dollars in actual net cash flow.You also want to know: how much will that asset be worth (vs now)?

2) Just live off of net cash flow that the paid off properties are generating each month?

For instance, the basement was leaking water from one wall and the seller had to put up gutters with downspouts leading far enough away from the house.

We have about 100 leads we’re gonna send out post card first, then follow up with letters every Friday for about 7 weeks. 

So, I doubled my leads for free.

I have looked at comps (Versailles, Strata, P&P, and so on) which are "filled" and generating the rents I would like, however I am concerned that the "A Type" market I am shooting for is extremely limited, and could be eliminated should Allentown start swinging back the other direction.
