And what do you do once they move in and cancel the renters insurance or let it expire?

I have been tracking expired listings within a 5 mile radius of where I live.

If you have concern about investors not funding, might I suggest that you require any interested investors to replace your earnest money prior to the expiration of the option period.

I've got one Realtor sending me any manufactured homes, and expired manufactured home leads.

So I am trying to stick it out with the company until those agreements expire.  

Let's say I move forward with it's advice and I draft a contract with several 'stacked' 179 day option terms, essentially letting the option expire and renewing it several times, when necessary.

My lease expires in April so I'd rather make moves before then.Should I, invest in the cheaper areas in Maryland like Prince George's County or Montgomery county.

Myself and another BP member are going to go through and reach out to expired listings on homes that (among other criteria) required a special sales contract.

Nope you would need to wait until the lease expires.

Mike, these are called 'expired listings' and yes, its a decent lead source.
