To your question, I get leads with a prospection software or just walking up the streets and looking for signs of distress.

I'm about to start calling contractors to see if I can get them to do a walk through of a potential deal I'm looking at doing. is there anything I should have for the contract?

So with this basement conversion my home will become a 2 unit dwelling (being that I'm walking distance to the Brookland metro and CUA Catholic University of America) it should rent for $1300 - $1500 easy.  

I'll walk you though the process if you are interested. 

That's why we also choose high-end finishes to get great tenants and top rents - here is a walk-through video on some of the things we typically do. 

5-10minute walk from the beach.

I walked over and said, um.. you're THAT upset about beautiful flowers outside your window?

Location wise, it was close to the freeway and could walk to stores and restaurants but the negative factors outweighed the positive. 

This allows the PM or leasing agent to walk through by themselves and show those 10 people the property all at one time, and they can all ask questions as well.

I think @Russell Brazil is correct that you are not having a flood of buyers walking thru.
