I'm sure there is a premium when it comes to remodeling considering the possibility of running into asbestos. I'd figure this is accounted for when selling as well. There are asbestos test kits for sale to confirm presence.

May as well start getting some bids from contractors where they could assess the state of plumbing, electric, etc. and give advice on how to move forward.

You sure you want to lose all plausible deniability?

I would start with a realtor familiar with the rental market (hopefully is a landlord themselves). They can let you know what is needed to get it rented vs. sold. Then talk to contractors to execute both plans. That would give you an idea of the cost to renovate to rent or sell, or just sell as is.
