Make sure on your rental agreement that people understand they are renting a room with shared access and responsibility for the common areas.

HELOC or Cash-Out Refinance would be the two most common ways to access that equity.

I have a sfh home with a detached garage at the rear of the property, the property is a corner lot with an alley behind the garage so there is access from both sides of garage.

Depends on access.....likely will need a tow behind concrete pump to get it in place.

I already have access to a venue.

When could get access to do that?'

The common area things they provide and their looks of the entryway provided will also help you know what to look for when purchasing.It's location is very important as well as its access. 

I love the Marietta area because its close enough to the city to have things to do but it is a quick shot just a few minutes from parks and outdoor space.

Here it means you designate your property to conservation purposes and open space.

I am doing some demo and reconnecting office space to increase the total area.
