Good luck and if you decide to door knock or hand out business cards to random people, give an update on how it went!  

Building departments also often have a lot of handouts and informational material they can provide so i would see what information you can get while you're down there as well. 

Hand out your card to every investor there telling them you will help them with the things I've just list above. 

You also can't give an option beyond the term of your purchase agreement. " Do you mean to say that if I do a CFD, and then hand out a lease option to a tenant buyer, I must first fufil my CFD contract before the lease-option cean be exercised by the tenant buyer?

Some of the less expensive (<$500) ways to start marketing: Website, bandit signs, hand-written yellow letters, postcards, door hangers, business cards (that I hand out like candy), fliers...I'm getting started on a shoestring myself and, if you take out the $1000 direct-mail campaign I'm doing, I've spent less than $500 and have had half a dozen leads and one potential deal on the cooker.

I don't want to just walk up to them and just say "tell me everything you know" like I'm looking for a hand out, but I don't know how much I can offer them either at this point.

The Missouri attorney general even puts out a little booklet that we hand out at every lease signing which I think is great.   

Hand out business cards and ask people if they are thinking of sell any property they have.

I am looking at yellow letters, bandit signs, car magnets, flyer handout or door hangers. 

Also as we built trust with our handyman and the tenants he was able to handle some items for us (repairs/app handouts/ unlock units for showings/ assist with tenant move ins)  ideally its nice to have someone on site in an office but not all complexes that size even have office space.
