But as Tim said the block closest to Belair Rd is the sketchiest. 

It's not everyone drinking the Kool Aid, you will learn so much and they have a message board of all PMs.

Especially now that you've posted your suspicions on a public forum, I'm not an attorney, but I've watched enough Law and Order that I could see there being the possibility of you being charged for "Aiding and Abetting" their crime by not reporting it or "Criminal Facilitation". 

You have broke college kids who are relying on financial aid to pay their rent.

It’s closest to your location.

This is the only laundromat in the town, with the next closest one being 45mins away. 

Although, we are not a beach community both Ft Myers Beach and Sanibel (our closest beaches) are in very rough shape.

Offer to pay the neighbors a reasonable amount say $50 - $100/mo. as they're doing you a GRAND favor helping you and besides that extra money may aide with commuting costs to work or a boost to their monthly budget or a their savings account!

It is actually assessed (taxable value) that seems to be the closest indicator to the selling price.

Otherwise about the closest you can get is something like PropHawk in Texas....this is probably the best, or maybe PropStream or DealMachine.
